Introductory Comment

Throughout  this Annual  Report  on  Form  10-K,  unless  otherwise  indicated  or  the  context  otherwise  requires,  the  term  “B6
Sigma” refers to B6 Sigma, Inc., a Delaware corporation, which, until the short-form merger referenced below, was our wholly-owned,
operating company acquired in September 2010; the terms the “Company,” “Sigma,” “we,” “us” and “our” refer to Sigma Labs, Inc.,
together  with  B6  Sigma,  Inc.  Prior  to  December  29,  2015,  we  conducted  substantially  all  of  our  operations  through  B6  Sigma.  On
December 29, 2015, we completed a short-form merger of B6 Sigma into Sigma. As a result, B6 Sigma became part of Sigma and no
longer exists as a subsidiary.

PART I

ITEM 1. BUSINESS.

Summary

Sigma  is  a  software  company  that  has  developed  quality  assurance  software  known  as  PrintRite3D®,  which  Sigma  believes
solves the major problems that have prevented large-scale metal part production using 3D printers...real-time computer-aided inspection
(CAI).  GE Aviation,  for  example,  has  stated  that  it  plans  to  commit  $3.5  billion  by  2020  to,  among  other  things,  build  a  metal  3D
production facility for its Leap engine and other engines to produce the applicable 3D printed parts. However, without companies like
GE Aviation effectively being able to check each part for shape, density, strength and consistency real-time during the manufacturing
process,  we  believe  that  such  companies  will  not  be  able  to  address  the  major  problems  currently  preventing  large-scale  metal  3D
production. We believe that our software, which is positioned “inside” the 3D metal printer, solves these problems by assuring each part
is being made to the specifications of the computer file as it is being made. We enable 3D prototyping to become 3D manufacturing.
Instead of performing quality assurance (“QA”) post production, our PrintRite3D® software could fundamentally redefine conventional
QA by embedding quality assurance and process control into the manufacturing process in real time. We have filed patent applications
directed to our In-Process Quality Assurance™ (“IPQA®”) procedure for advanced manufacturing. In addition, we anticipate that our
core  PrintRite3D®  software  will  enable  our  customers  to  combine  their  advanced  manufacturing  technologies  with  our  3D
manufacturing QA to achieve both cost savings and stronger parts. Vertical markets that we believe would benefit from our technology
and software include aerospace, defense, bio-medical, power generation, and oil & gas industries. We provide our software products to
customers in the form of Software as a Service (“SaaS”).

About 3D Printing

3D printing (“3DP”) or additive manufacturing (“AM”) is changing the world by going directly from computer graphics to real
parts.  3D  printing  has  been  applied  to  the  manufacture  of  plastic  parts  for  several  years.  3D  manufacturing  of  metal  parts  involves
directing  a  laser  or  other  energy  source  at  a  layer  of  powdered  metal  and  melting  it.  These  layers  become  melted  together  from  the
bottom  up.  Revenues  attributable  to  3D  manufacturing  for  metal  products  were  $88.1  million  in  2015  (Wohlers  Report  2016,  3D
Printing and Additive Manufacturing State of the Industry – Annual Worldwide Progress Report).

The application of 3D printing to high-tolerance, precision manufactured metal parts has only recently emerged. 3D printing of
metal parts today represents only a minor percentage of all 3D manufacturing. However, we believe the greatest future growth for 3D
printing  appears  to  be  in  metal  parts  given  the  interest  and  investment  being  made  by  Fortune  100  companies,  Federal  government
laboratories and agencies as well as university-based institutions. Emphasis from these high-end manufacturers and technology leaders
is strongly focused on quality and precision manufacturing for high-tolerance parts. We believe the on-going success of 3D printing for
metal parts will be highly dependent upon the quality assurance procedure used such as our PrintRite3D® methodology.

About Quality Assurance in 3D Printing

Current methods for providing quality are cost prohibitive because approximately 25% of parts produced by 3D printing need
to  be  destroyed  in  the  post-production  quality  control  process. Additional  costs  are  incurred  by  using  non-traditional  x-ray  scanning
technology on these parts. We offer our clients the ability to use real-time sensors to track each layer, and our software continuously
analyzes the part so that when it is finished we know if it is production quality. We believe our PrintRite3D® software could reduce
inspection costs by a factor of 10 and development time for new parts by 50% or more.

By using PrintRite3D® software, a high-precision manufacturer would have the ability to offer its customers, on an exclusive
basis, product guarantees and assurances that its product was produced in compliance with stringent quality requirements. Initial orders
have been received from GE Aviation, Honeywell Aerospace, Aeroject Rocketdyne, Woodward, Siemens and Pratt & Whitney.

We believe there is potential for our PrintRite3D® software to be incorporated into a majority of 3D metal printing devices
made  by  companies  like  Electro-Optical  Systems  (“EOS”), Additive  Industries,  Concept  Lasers,  Trumpf  Lasers,  Renishaw,  Sentrol,
Farsoon and others.

Sigma’s Cloud-Based IIoT Solutions

The process of making a 3D printed part could start with our customers loading a CAD model of the part into the Cloud shown
in “A” in Figure 1. Next, CAE/CAM instructions are sent to the 3D printer (see “B”, as shown in Figure 1). Metal powder in the machine
is then deposited onto the build platform where a laser beam or other energy focused onto the build platform melts each successive layer
of powder in 20-50 micron increments. Our CAI sensors (see “C” in Figure 1) detect, record, analyze and compare the part as it is being
made layer-by-layer against the CAD specifications and physical reference points for quality assurance during the manufacturing. Our
software certifies the shape, strength, and internal density of each part, which eliminates the need to: (1) destroy a large percentage of
the parts during process validation and in post-production quality assurance; and (2) retain all of the metal as opposed to cutting pieces
and wasting metal.

Our PrintRite3D® CAI web-based software (see “D” in Figure 1) is being designed to reside in the Cloud (see “A” in Figure 1)
of the Industrial Internet of Things (“IIoT”). We enable manufacturing engineers to assure the part quality layer-by-layer, provide for
manufacturing statistical process control and harvest, aggregate, and analyze Big Data from the manufacturing real-time data collected
from our PrintRite3D® SENSORPAK™ (see “C” in Figure 1), as well as post-process manufacturing data collected by our customers
(see “E” in Figure 1).

Our  specialized  sensor  suite  (see  “C”  in  Figure  1),  known  as  PrintRite3D®  SENSORPAK™,  is  an  IIoT-compliant  edge
computing device. It contains the modular hardware and software necessary to connect to “cyber-physical” objects (see “B” in Figure 1)
living on the manufacturing floor. It allows for bi-directional information flow between the manufacturing floor and the Cloud (see “A”
in Figure 1). It starts a million-fold data reduction that finishes with our PrintRite3D® CAI software, which provides customers with
product  guarantees  and  assurances  that  parts  were  produced  in  compliance  with  stringent  quality  standards.  It  can  collect,  analyze,
aggregate, filter, and then further communicate data from the manufacturing floor to the Cloud (see “A” in Figure 1) and enable links to
other areas (see “F” in Figure 1) of the IIoT.

We  generate  revenues  through  PrintRite3D®  hardware  and  sensor  sales  and  CAI  software  licensing  of  our  PrintRite3D®
technology to customers that seek to improve their manufacturing production processes, and through ongoing annual software upgrades
and  maintenance  fees.  Additionally,  we  generate  revenues  from  our  contract  manufacturing  activities  in  metal  AM.  By  running  a
contract AM services operation, we are able to understand the current needs of our customers and where they are going with their next-
generation product development efforts. Contract AM further allows us a means for continuing/self-funding our IPQA®-enabled R&D
and product development activities for PrintRite3D® CAI software. We provide our AM contract manufacturing services to customers
in the form of Quality as a Service (“QaaS”). Starting with our PrintRite3D® cloud-based SaaS model, customers will contract with us
for CAE, CAM and CAI services to generate and establish a digital quality record (“DQR”) for AM built parts. Each DQR is cloud-
based and allows for archiving and storage of quality data, access to our big data ANALYTICS™ software App for continuous quality
monitoring and improvement, and automatic industry benchmarking while maintaining firewalls between company-specific data.

In  late  2015,  we  launched  two  programs −  an  Early  Adopter  Program  (“EAP”)  and  an  Original  Equipment  Manufacturer
(“OEM”)  Partner  Program − designed to broaden our market presence and speed adoption of our PrintRite3D® technology. The EAP
was  designed  to  attract  end  user  customers  who  have  an  existing,  installed  base  of  3D  metal  printers  and  to  offer  them  incentivized
pricing  in  return  for  feedback  on  initial  and  beta  releases  of  our  PrintRite3D®  software  Apps.  Our  OEM  Partner  Program  was
specifically designed for AM machine manufacturers seeking to embed our PrintRite3D® quality assurance software Apps directly into
their machines for customers purchasing a turnkey solution for their new AM machine purchases.

We possess the resident expertise to provide manufacturing materials and process (M&P) engineering services and support to
companies using our PrintRite3D® software Apps for metal AM. Accordingly, in addition to our primary business focus, we intend to
generate revenues by providing such manufacturing engineering services and support to businesses licensing our PrintRite3D® software
Apps.

Additionally, our President and Chief Executive Officer has worked at or with the Edison Welding Institute, the United States
Department of Energy (“DOE”) national laboratories (including the Knolls Atomic Power Laboratory, Bettis Atomic Power Laboratory,
Los Alamos National Laboratory and Sandia National Laboratory) over the last 32 years. Due to his work with the DOE, our President
and Chief Executive Officer has developed extensive relationships with the DOE and its network of national laboratories. Accordingly,
we expect to leverage these relationships in connection with licensing and developing technologies created at such national laboratories
for commercialization in the private sector.

Early-Stage Technology Commercialization and Market Positioning

Since our inception in 2010, we have made progress in bringing early-stage disruptive technology from scientific concept and

curiosity to practical reality, as described below.

PrintRite3D® Quality Assurance Software for Computer-Aided Inspection of Metal Additive Manufacturing.

We believe that AM will significantly impact the manufacturing landscape. AM results in very efficient metal utilization for
parts  made  on-demand,  and  utilizes  a  wide  variety  of  rapid  prototyping  methods.  As  a  result  of  AM,  parts  can  go  straight  from
computer-aided designs (CAD) and 3D computer models to actual, physical parts through the use of computer-aided engineering (CAE)
and computer-aided manufacturing (CAM) steps. However, there are severe challenges in connection with 3D printing of metal parts.
Current manufacturing processes are not capable of making every part right the first time. Also, process consistency and repeatability
require further development for metal parts and this is a typical case for emerging technologies. Although many industry experts have
lamented that 3D Printing for metal parts is limited in current applications, we are developing our IPQA®-enabled technology into a
hardware and software suite of products for CAI of AM known as PrintRite3D®, which we expect will address some these shortcomings
and enable mass production for metals AM technology to be realized sooner than would otherwise be possible given its current state of
maturity. PrintRite3D® comprises a suite of CAI software apps that address the three fundamental problems facing metal AM today,
namely:  assuring  the  metal  integrity  or  quality  of  the  product;  assuring  the  as-built  geometry  of  the  product;  and,  increasing  the
productivity or speed of the AM process.

Contract Manufacturing for Metal Additive Manufacturing.

According to the Wohlers 2016 Annual Report, industry growth in the service provider segment in 2015 was an estimated $2.8
billion, an increase of 33% from $2.105 billion in 2014. This market segment grew by 38.9% in 2014, 26.3% in 2013, and 36.4% in
2012. End users are still in the early stages of adding metal AM systems to supply production parts to aerospace and defense OEMs,
such  as  GE Aviation  (“GEA”),  Honeywell Aerospace,  Pratt  &  Whitney,  and  Siemens  Turbomachinery.  We  believe  that  most AM
machines  produced  through  2016  are  still  not  well  suited  for  production  applications.  They  have  limited  feedback  measurement  and
control sensors to guarantee part quality real time. Some of the latest machines available, such as EOS’s M290 machine, are beginning to
be sold with limited advanced measurement system capability.

We  believe  that  this  service  provider  market  segment  represents  an  opportunity  for  us  to  capture  significant  portions  of  the
demand for metal production parts. Accordingly, we acquired our first EOS M290 metal printing machine in 2014. Using the M280 as
its  base,  the  M290  adds  improved  energy  efficiencies,  faster  build  times,  and  slightly  larger  build  platform  capabilities.  Through  our
EOS  M290  machine,  our  customers  will  gain  the  benefits  of  many  years  of  M280-proven  applications  while  accessing  the  latest  in
DMLS® technology, as well as receiving parts certifiably produced using our state-of-the-art PrintRite3D® quality assurance software
Apps. We provide our AM contract manufacturing services to customers in the form of Quality as a Service.

A detailed description of our technologies and business follows.

PrintRite3D® Quality Assurance Software for Additive Manufacturing

The Market

An area of increasing interest in the manufacturing world is AM or 3DP. AM is a method of producing functional parts directly

from computer design or CAD files without any tooling or other processing.

The sale of AM products and services is expected to exceed $8.8 billion worldwide in 2017. The AM industry is expected to
grow to about $15.8 billion in 2019. In 2021, the AM industry is forecasted to grow to about $26.5 billion, all according to the Wohlers
2016 Annual Report.

Metal parts are a rapidly growing segment of this overall market space as AM or 3D printing moves from just making models
to  making  actual,  fully  functional  parts.  Large  end  users  such  as  Honeywell Aerospace,  GEA  and  Boeing  Defense  view AM  as  an
enabling process for many components. A recent report in a series by Deloitte University Press on additive manufacturing published in
Fall 2015 titled, “3D Opportunity For Quality Assurance and Parts Qualification”, states that, “[o]ne of the most important barriers is the
qualification of AM-produced parts. So crucial is this issue, in fact, that many characterize quality assurance (QA) as the single biggest
hurdle to widespread adoption of AM technology, particularly for metal.” We believe that OEM end user companies as well as first-tier
suppliers cannot achieve their long-term AM production goals without advanced quality assurance and control technologies for metal
AM  parts  because  current  quality  control  methods  are  not  sufficient  to  reliably  allow  cost-effective  manufacturing  of  safety-  and
performance-critical metal parts. We believe that our PrintRite3D® CAI technology would directly address this “important barrier” for
metal parts and allow such AM applications to move forward. In response to this need, we have experienced an increase in our installed
base  of  PrintRite3D®  systems  and  we  are  beginning  to  provide  material  &  process  engineering  services  and  support  for  our
PrintRite3D®  software  licenses  for  our  installed  base  at  GEA,  Honeywell  Aerospace,  Spartacus3D,  Additive  Industries,  Aerojet
Rocketdyne, 3D Material Technologies, LLC, Woodward, Siemens, Pratt & Whitney, and the Edison Welding Institute (“EWI”).

8

We have ongoing contracts that include a Phase 3 project with Honeywell Aerospace funded by the Defense Advanced Projects
Agency  (“DARPA”)  on  the  application  of  our  PrintRite3D®  technology  to  performance-critical AM  metal  parts  for  aerospace.  This
project  is  vitally  important  because  it  provided  an  early  opportunity  to  demonstrate  how  our  IPQA®-enabled  PrintRite3D®  software
Apps will reduce our customers’ reliance on unnecessary post process inspection, ultimately reducing costs and improving quality for
AM of highly critical aerospace metal components. Also, we were a participant on a GEA led team of companies and universities, which
was awarded a research contract by the National Additive Manufacturing Innovation Institute (“NAMII” or America Makes) titled, “In-
Process  Quality Assurance™  for  Laser  Powder  Bed  Production  of Aerospace  Components”.  The  contract  has  the  stated  objective  of
maturing our In Process Quality Assurance™ (IPQA®) technology for aerospace applications by leveraging a development  approach
incorporating multiple AM OEM machines, multiple superalloys, and multiple product intent aerospace components. In support of this
effort, we were awarded related contracts from the subcontractor Aerojet Rocketdyne to install one of our PrintRite3D® systems and
software Apps  on  a  Concept  Laser  M2  metal AM  machine  at Aerojet  Rocketdyne’s  Canoga  Park,  California  facility,  as  well  as  a
contract from Honeywell Aerospace to make initial test specimens for reliability and repeatability testing using our EOS M290 printer.
We were also part of a large research team, led by the Edison Welding Institute that was awarded a grant funded by the National Institute
of Standards (“NIST”) to ensure that quality parts are produced and certified for use in products made by a variety of industries and their
supply chains. The emphasis was on providing tools needed for additive manufacturing applications to progress from prototype to serial
production. This program was successfully completed in Fall 2015. We are currently a subcontractor to Honeywell Aerospace who was
awarded a program in 2015 by America Makes which is designed to address Design for Additive Manufacturing (“DFAM”) issues. In
support of this program, we will use our EOS M290 printer to build canonical shapes and mechanical test specimens for evaluation by
Honeywell Aerospace.

Technology and Competitive Advantage

The  evolution  of AM  from  prototyping  to  volume  manufacturing  in  production  runs  is  occurring  in,  and  led  by,  aerospace
while also appearing in niche products such as medical appliances and replacement parts of diverse applications, including unavailable
parts required by still deployed but aging technologies. A major problem for 3D metal products production-run manufacturing today is
that traditional quality systems rely heavily on after-manufacture inspection procedures that lack strong statistical reliability in small lot
manufacturing.  Post-production  non-destructive  test  instruments  from  ultrasound  to  CT  Scans  are  either  not  effective  or  not  cost
efficient  on  many  complex  part  configurations  that  take  advantage  of  3D  capability,  and  in  the  case  of  CT  scans,  are  prohibitively
expensive  for  production  cost  efficiency.  The  most  important  feature  of  our  PrintRite3D®  is  that  it  develops  actionable  quality  and
process control data of manufacturing  information  in  real-time  and,  when  no  flaws  are  detected,  can  provide  manufacturers  and  their
end-users with a part-by-part quality certification backed up by a file of supporting data.

Our  PrintRite3D®  suite,  as  described  below,  is  composed  of  hardware,  software,  data  analytics,  and  proprietary  algorithms.
The  hardware  is  an  array  of  photodiodes,  non-contact  pyrometer,  and  a  data  processing  unit  that  can  be  either  sold  with  an  AM
manufacturing machine unit by an OEM manufacturer or retrofitted on customers’ sites.

·

·
·

PrintRite3D®  SENSORPAK™  –  the  auxiliary  sensor  and  hardware  kit  that  sits  on  every AM  machine  to  collect  the
data to drive the software.
PrintRite3D® INSPECT™ – software which verifies quality layer by layer.
PrintRite3D® CONTOUR™ – software which assures the as-built geometry.

The following software modules are currently in development:

·

·

PrintRite3D®  ANALYTICS™  –  software  that  harvests,  aggregates,  and  analyzes  big  data  from  in-process
manufacturing data and post-process manufacturing data.
PrintRite3D® THERMAL™ – software which predicts the residual stress and distortion in the part.

The proprietary software and its embedded algorithms process the very substantial quantity of layer by layer data gathered and
then informs operators of the Quality Compliance status of each part in a build. We have been active in patent protecting our in-depth
data analysis and quality algorithms to link our analysis to root cause metallurgy for determining the granular quantification of the part
conformance to metallurgical requirements such as tensile strength. Concurrent with assessing the internal quality features of all parts in
a build, PrintRite3D® deploys its CONTOUR™ module that measures each part’s adherence to the configuration specification of both
internal  channels  and  external  form.  OEM  machine  manufacturers  as  well  as  control  system  manufacturers  may  use  the  Sigma  data
stream to direct machine performance adjustments.

We  have  developed  a  tool  that  enables  companies  using Additive  Manufacturing  equipment  for  metal  parts  to  move  from
prototyping on into production runs by assuring quality in a uniquely reliable and cost effective fashion. Not only does PrintRite3D®
enable a single AM machine to operate at high quality yields, by measuring the product of the manufacturing equipment rather than just
the  equipment  settings,  it  also  is  a  reliable  method  to  assure  and  document  uniform  quality  assurance  of  a  single  part’s  specification
being manufactured by factories utilizing a number of different AM machines.

We believe that the broad domain coverage of our PrintRite3D® patents and metallurgical know-how make the licensing of our
product  suite  to  be  the  best  means  by  which  Additive  Manufacturing  OEM  equipment  manufacturers  can  offer  in-process-quality-
monitoring  that  certifies  and  documents  the  quality  of  all  parts  that  pass  continuous  inspection.  PrintRite3D®  provides  3D  metal
manufacturing  equipment  makers  with  a  patent  protected  data  configuration  of  information  that  the  manufacturers  may  use  to  adjust
controls  of  their  equipment  in  response  to  real-time  quality  information  by,  for  example,  precisely  adjusting  laser  power  to  sustain
manufacturing to design and specification.

Our IPQA®-enabled PrintRite3D® software Apps appear well suited to meet the needs of metal AM at this critical juncture in
its development. Our technology will allow metal AM to be used during manufacturing of safety-critical or performance-critical metal
parts, such as used in aerospace, defense and biomedical. Currently, these applications are difficult because the part quality cannot be
completely guaranteed using today’s conventional nondestructive inspection technologies, because using inspection after manufacturing
is difficult, costly and does not find all defects of concern. Therefore, we believe that PrintRite3D® could be an enabler for metal AM to
realize  its  full  potential.  We  have  unique  and  patent  protected  offerings  in  this  field.  Furthermore,  as  a  greater  number  of  these AM
applications  could  be  cloud-based,  the  PrintRite3D®  technology  is  fully  compatible  with  highly  networked,  cloud-  or  web-based
implementation – subject to the data and intellectual property restrictions which may be imposed by some companies for competitive
reasons.

Our  proprietary  PrintRite3D®  software  Apps  have  been  demonstrated  and  tested  at  many  manufacturing  sites  around  the
world.  We  believe  these  demonstrations  have  served  to  validate  the  underlying  technology  of  PrintRite3D®  INSPECT™  and
SENSORPAK™ software and hardware modules, respectively. In addition, we have developed relationships with experienced aerospace
companies  in  North America  that  have  assisted  in  the  validation  of  the  underlying  technology  for  our  PrintRite3D®  software App
known as CONTOUR™.

We continue to work with General Electric under our Joint Technology Development Agreement (“JTDA”), dated April 10,
2013, to demonstrate and implement our in-process inspection technologies for additive manufactured jet engine components. We are
continuing to work with Honeywell Aerospace on the separate development of our PrintRite3D® CONTOUR™ software App for metal-
based AM  under  our  Trial  Evaluation Agreement  with  Honeywell Aerospace,  which  sets  forth  the  parties’  intent  to  use  Honeywell’s
Advanced Manufacturing Engineering Center as a beta test site for our PrintRite3D® CONTOUR™ software module. In further support
of this effort, in 2015 Honeywell Aerospace installed its second PrintRite3D® system on one of its Concept Laser M2 machines at their
Advanced Manufacturing Engineering Center in Phoenix, Arizona.

We have expanded our market presence and associated installed base of PrintRite3D® systems through our EAP and our OEM
Partner Program to include European companies in France, Germany and The Netherlands. These European partners’ installations are
key to our long term strategy to broaden its installed base through our EAP as well as gain market presence though embedded OEM
offerings  of  our  PrintRite3D®  technology.  Our  PrintRite3D®  product  commercialization  efforts  reflect  the  strategic  nature  of  our
selective alliance partnerships.

We  believe  PrintRite3D®  is  uniquely  positioned  to  grow  into  this  market  as  its  technology  is  platform  independent  and

deployable with all currently known metal AM manufacturing units.

Business Model

Our current commercialization strategy for PrintRite3D® products is:

·

·

·

·

Enter into early adopter license agreements with high potential future AM equipment manufacturers and complex part
AM manufacturing service bureaus;
Enter  into  OEM  license  agreements  for  PrintRite3D®  to  be  manufactured  directly  into  the  printers  of  major  AM
equipment manufacturers;
Provide manufacturing engineering consulting services to third parties that have needs in developing quality assurance
tactical methods for manufacturing; and
Build and run a contract manufacturing division for metal AM commencing with our EOS M290 state-of-the art metal
printer.

PrintRite3D® is designed to run on different machine platforms which allow us to maximize our product offering to the entire

AM metal market. The target markets include OEMs both on the AM software side as well as OEM machine producers and end users.

We  believe  another  much  needed  area  for  AM  metal  parts  manufacturing  is  in  software  Apps  for  reducing  design  and
development  cycle  times,  saving  the  end  customer  time  and  money.  In  support  of  that,  in  2016,  we  entered  into  a  Technology
Development  Agreement  with  3DSIM,  LLC  of  Park  City,  Utah,  to  pursue  commercial  metal  AM  software  opportunities  for  rapid
qualification  and  part  certification.  These  software Apps  could  form  the  underpinnings  and  backbone  of  a  conceptual  software App
known  as  THERMAL™.  We  expect  in  the  future  to  attempt  to  develop  and  offer  a  PrintRite3D®  suite  of  Apps  which  would  be
specifically developed to improve part  designs  and  reduce  traditional  trial  and  error  design  approaches  for  features  such  as  distortion
control.

To summarize, we have formed an operating division focused on real-time, advanced quality assurance solutions for additive
manufacturing  thereby  increasing  the  value  of  the AM  part. Although  in  the  past  our  revenues  have  been  generated  mainly  through
engineering consulting services we provided to third parties, We have generated revenues from December 2013 through December 2016
through sales and licensing of our PrintRite3D® systems and software.

Contract Manufacturing for Metal Additive Manufacturing

The Market

According  to  the  Wohlers  2016  Report,  in  2015  the Additive  Manufacturing  industry’s  primary  and  secondary  worldwide
revenues were $7.024 billion, up 22% from 2014. Wohlers forecasts that AM’s primary revenues alone will top $8.8 billion in 2017. Our
initial  target  market  within  this  burgeoning  marketplace  is  the  production  of  metal  parts.  According  to  figures  for  2015,  revenues
attributable to metals for AM are estimated to be over 17% of the total revenues in the AM markets.

As demand continues to increase for AM prototyping services, contract AM service bureau providers that can deliver low-rate
initial  production  capacity,  and  as  commercial  companies  in  highly-regulated  industries  begin  to  gain  regulatory  acceptance  for AM
designed parts, we believe there is a burgeoning need for contract manufacturing services to produce these much need metal AM parts.
The existing service bureau for AM parts has become much smaller today as a result of merger and acquisition activities since 2012, and
we believe what remains is small, fragmented and less capable than the first generation of service bureau providers.

Also launched in 2015, Arete-Sigma is a joint venture targeting contract AM manufacturing as it anchors the Company’s entry
into  day-to-day AM  manufacturing.  The  Company  is  pursuing  business  opportunities  away  from  the  joint  venture  utilizing  its  EOS
M290 printer or like machines.

Technology and Competitive Advantage

We  currently  have  an AM  3D  metal  printing  facility  that  employs  state-of-the-art  technology  from  the  leading  provider  of
metal AM  systems,  Electro-Optical  Systems.  While  our  current  printing  capacity  is  limited,  we  believe  that  a  unique  selling  point  or
competitive  advantage  is  our  PrintRite3D®  technology.  Our  EOS  M290  printer  is  outfitted  with  our  latest  PrintRite3D®-enabled
technology  allowing  us  to  provide  customers  with  the  necessary  objective  evidence  of  compliance  to  design  intent,  or  QaaS  data
package, to ensure they can meet compliance with their design intent and ultimately end-user performance requirements for their highly-
critical  and  demanding  components.  Our  Quality  as  a  Service  starts  with  our  PrintRite3D®  cloud-based  SaaS  model.  Customers  will
contract with Sigma to generate and establish a digital quality record for AM built parts based on Design for Additive Manufacturing
(“DFAM”)  principles.  Each  DQR  is  cloud-based  and  allows  for  archiving  and  storage  of  quality  data,  access  to  our  big  data
ANALYTICS™  software  App  for  continuous  quality  monitoring  and  improvement,  and  automatic  industry  benchmarking  while
maintaining  firewalls  between  company-specific  data.  Our  QaaS  service  benefits  our  customers  by  providing  independent  quality
assurance  and  increased  process  intelligence  and  access  to  our  latest  big  data  sophisticated  and  proprietary ANALYTICS™  software
Apps for trending and additional manufacturing intelligence.

Business Model

We envision a business model comprising revenues from contract, metal AM manufacturing sales for prototyping services as
well as QaaS sales for low-rate initial production parts requiring our PrintRite3D® digital quality records. These DQRs can be used by
our customers for:

·
·
·

Internal use at their captive AM facility to make parts;
Incorporated as a quality requirement to their vendor base supplying AM parts; or
Contract back to us to supply AM parts.

This model allows us to realize revenues through further PrintRite3D® software sales and licensing or revenues from contract
AM  manufacturing  services.  The  target  markets  would  be  end  users  requiring  high-end  metal  parts  such  as  in  the  aerospace,  bio-
medical, power generation, and automotive markets.

To  summarize,  we  have  formed  an  operating  division  focused  QaaS  which  is  based  on  its  contract  additive  manufacturing
capability and its AM facility keeps us on the cutting edge of 3D metal additive manufacturing as we work with the market to develop
state  of  the  moment  solutions  and  to  characterize  new  materials  and  newly  born  DFAM  parts.  The  operations  are  at  an  early  stage,
limited, and revenues are reflective of its early stage.

Recent Developments (in reverse chronological order)

On  March  29,  2017,  we  announced  that  we  entered  into  a  long  term  non-exclusive  commercial  agreement  with  Additive
Industries B.V. of The Netherlands. As part of the multi-year agreement, anticipated to be worth several million dollars over the next
few years, Additive Industries will join our previously-announced OEM Partner Program – embedding and reselling our PrintRite3D®
software within our AM equipment.

In an effort to bring enhanced solutions for additive manufacturing (“AM”) to the aerospace and defense (“A&D”) sector and
capitalize on growth in demand for 3D printed metal components within the A&D industry, we recently entered into a strategic alliance
with  Morf3D,  a  California-based  company  that  specializes  in  additive  engineering  and  manufacturing  with  metals  and  that  provides
advisory services in additive manufacturing strategy and technology adoption road-mapping. By leveraging our PrintRite3D® quality
assurance software, we believe that Morf3D will be able to provide a means for its customers to increase AM production rates while
ensuring  consistent  part  quality,  thereby  better  meeting  the  high  quality  demands  of  its  aerospace  customers.  We  also  plan  to  work
together with Morf3D to manufacture certain 3D printed parts. Morph3D has informed us that it is a party to development contracts with
aircraft, space, medical and automotive customers, and that it expects to commence serial production contracts in 2017. We believe that
by working together with Morf3D, we will be in a position to design, manufacture, and assure the quality of AM components across a
number of important aerospace applications, which could lead to the generation of a meaningful amount of additional revenue for our
company beginning in 2017.

Competition

We believe our technologies will be beneficial to several industries, including aerospace, defense, oil and gas, bio-medical, and
power generation. However, developments by others may render our current and proposed technologies noncompetitive or obsolete, or
we may be unable to keep pace with technological developments or other market factors. Additionally, our competitive position may be
materially  affected  by  our  ability  to  develop  or  successfully  commercialize  certain  technologies  that  we  have  identified  for
commercialization.  Other  general  external  factors  may  also  impact  the  ability  of  our  products  to  meet  expectations  or  effectively
compete, including pricing pressures.

We  anticipate  some  of  our  principal  competitors  in  the  United  States  will  include  AM  End  Users,  such  as  GE  Aviation,
Honeywell Aerospace,  Rolls-Royce  PLC,  Pratt  &  Whitney; AM  OEM  equipment  manufacturers,  such  as  EOS,  Concept  Lasers,  3D
Systems,  Renishaw, Arcam  and  SLM;  third  party  solution  providers  like  Stratonics  Inc.,  and  Vibrant  Corporation  that  specialize  in
designing  and  manufacturing  quality  control  monitoring  devices  used  in  industrial  applications.  Most  of  these  competitors  have
significantly greater research and development capabilities than we do, as well as substantially more sales, marketing and financial and
managerial resources. These entities represent significant competition for us. In addition, acquisitions of, or investments in, competing
companies by large corporations could increase such competitors’ research, financial, manufacturing and other resources.

Research and Development

Research and development costs are expensed as incurred. Our research and development expenses relate to our engineering
activities,  which  consist  of  the  development  of  our  PrintRite3D®  quality  assurance  technologies  for  specific  customers  and  for  the
industry  in  general.  During  the  years  ended  December  31,  2016  and  2015,  we  recognized  $92,992  and  $330,554,  of  research  and
development costs, respectively.

Intellectual Property

We regard our patents, trademarks, domain names, trade secrets, know-how, and other intellectual property as critical to our
success.  We  rely  on a  combination  of patent,  trademark,  trade  secret,  other  intellectual  property  law,  confidentiality procedures,  and
contractual provisions with employees, partners, and others to protect the technology and other proprietary rights, information and know-
how  that comprise the core of our business. The below chart summarizes our issued patents. We are currently prosecuting ten foreign
and U.S. patent applications related to our IPQA® technology and rapid qualification of additive manufacturing for metal parts. Eight of
these  ten  patent  applications  published  between  November  2015  and  January  19,  2017.  There  is  no  guarantee  that  the  patent
applications we have submitted will issue or that if issued, they will offer adequate protection under applicable law.

Government Regulation

Any contracts that we enter into with governmental agencies will be subject to a variety of federal, state and local laws and
regulations.  These  regulations  are  aimed  at  preventing  the  inadvertent  disclosure  of  munitions  related  data  or  the  export  of  technical
knowledge to foreign countries. The work we do with governmental units may also be subject to laws respecting the confidentiality of
any classified or national security information we receive during the course of our activities under any government contract.

Additionally, with respect to our work with government agencies, our sales are driven by pricing based on costs incurred to
produce  products  or  perform  services  under  contracts  with  the  U.S.  government.  U.S.  government  contracts  generally  are  subject  to
Federal Acquisition Regulations (“FAR”), agency-specific regulations that implement or supplement FAR, such as the DoD’s Defense
Federal Acquisition  Regulations  and  other  applicable  laws  and  regulations.  These  regulations  impose  a  broad  range  of  requirements,
many of which are unique to government contracting, including various procurement, import and export, security, contract pricing and
cost,  contract  termination  and  adjustment,  and  audit  requirements.  A  contractor’s  failure  to  comply  with  these  regulations  and
requirements could result in reductions of the value of contracts, contract modifications or termination, and the assessment of penalties
and fines and could lead to suspension or debarment from government contracting or subcontracting for a period of time. In addition,
government contractors are also subject to routine audits and investigations by U.S. government agencies such as the Defense Contract
Audit Agency  (“DCAA”).  These  agencies  review  a  contractor’s  performance,  cost  structure,  and  compliance  with  applicable  laws,
regulations, and standards. The DCAA also reviews the adequacy of, and a contractor’s compliance with, its internal control systems and
policies, including the contractor’s purchasing, property, estimating, compensation, and information systems.

Employees

As of March 31, 2017, we had 11 full-time employees and one part-time employee. We are actively searching for additional,
qualified administrative and engineering staff, as well as sales and marketing staff, to support our expanding operations in the area of

ITEM 1A. RISK FACTORS.

Investing in our securities involves a high degree of risk. Our business is subject to numerous risks. We caution you that the
following important factors, among others, could cause our actual results to differ materially from those expressed in statements made
by us or on our behalf in filings with the SEC, press releases or communications with investors and others. Any or all of our statements
in  this  annual  report  and  in  any  other  public  statements  we  make  may  turn  out  to  be  wrong.  They  can  be  affected  by  inaccurate
assumptions  or  by  known  or  unknown  risks  and  uncertainties.  The  factors  mentioned  in  the  discussion  below  will  be  important  in
determining future results. Consequently, actual future results may vary materially from those anticipated in this annual report or our
other public statements. You should carefully consider the risks described below, as well as the other information in this annual report,
including our financial statements and the related notes and “Management’s Discussion and Analysis of Financial Condition and Results
of Operations,” before deciding whether to invest in our securities. The occurrence of any of the events or developments described below
could  harm  our  financial  condition,  results  of  operations,  business  and  prospects.  In  such  an  event,  the  market  price  of  our  securities
could decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we
currently deem immaterial also may have similar adverse effects on us.

Risks Related to Our Business

We have a limited operating history, are not currently profitable and may never become profitable.

We have incurred losses in every reporting period since we commenced business operations in 2010 and expect to continue to
incur  significant  losses  for  the  foreseeable  future.  Our  net  loss  for  the  year  ended  December  31,  2015  and  2016  was  $1,696,282  and
$2,196,834 respectively. As of December 31, 2016, our accumulated deficit was $9,760,954. There is no assurance that any revenues we
generate will be sufficient for us to become profitable or to maintain profitability. Our revenues for the year ended December 31, 2015
and 2016 were $1,234,810 and $966,422, respectively, and our operating expenses for those periods were $2,717,650 and $3,251,486
respectively.  Our  current  revenues  are  not  sufficient  to  fund  our  operations.  We  cannot  predict  when,  if  ever,  we  might  achieve
profitability and we are not certain that we will be able to sustain profitability, if achieved. If we fail to achieve or maintain profitability,
the market price of our securities is likely to be adversely affected.

We may require additional financing to continue our operations, and there is no assurance that we will be able to obtain such
financing on acceptable terms, or at all.

As of December 31, 2016, we had cash in the amount of $398,391. In February 2017 we closed an underwritten public offering
of 1,410,000 units consisting of one share of common stock and one warrant for gross proceeds of $5,823,300. We believe that the net
proceeds of approximately $5.25 million from the offering, together with our existing cash and anticipated revenues, will be sufficient to
fund our operations until at least January 2019, although there is no assurance that we will not require additional financing before that
time. There is no assurance that any future financing that we require to fund our operations will be available on acceptable terms, or at
all.  Such  financing,  if  in  the  form  of  equity,  may  be  highly  dilutive  to  our  existing  stockholders  and  may  otherwise  include  onerous
terms. Such financing, if in the form of debt, may include debt covenants and repayment obligations that are onerous and that adversely
affect our business operations. If adequate funds are not available to us, we may be required to delay, limit or terminate our business
operations.

Our limited operating history makes evaluation of our business difficult.

We  commenced  business  operations  in  2010  and  are  continuing  to  develop  our  technologies  and  to  implement  our  business
plan.  Our  ability  to  implement  a  successful  business  plan  remains  unproven,  and  there  is  no  assurance  that  we  will  ever  generate
sufficient revenues to sustain our business. Our relatively short operating history, together with the other risks discussed in this “Risk
Factors” section, may make it difficult for you to evaluate our business in connection with making a decision about whether to invest in
our securities.

We face the risks normally associated with a new business.

We face all of the risks inherent in a new business, including the expenses, difficulties, complications and delays frequently
encountered in connection with conducting new operations and efforts to develop and commercialize technologies. These uncertainties
include  developing  our  technologies  and  our  brand  name,  raising  capital  to  meet  our  working  capital  requirements  and  developing  a
customer base, among others. If we are not effective in addressing these risks, we will not be able to operate profitably in the future, and
we may not have adequate working capital to meet our obligations as they become due.

16

 
 
Our business may be adversely affected by a global economic downturn.

Any economic downturn generally could cause a drop in government spending and business investment, which would have a
material adverse effect on our business. Further, as a result of the current global economic situation, there may be a disruption or delay
in  performance  by  our  third-party  contractors  and  suppliers.  If  such  third  parties  are  unable  to  adequately  satisfy  their  contractual
commitments to us in a timely manner, our business could be adversely affected.

We could incur significant damages if we are unable to adequately discharge our contractual obligations.

Our  failure  to  comply  with  contract  requirements  or  to  meet  our  clients’  performance  expectations  on  a  contract  could
materially and adversely affect our financial performance and our reputation. This, in turn, would impact our ability to compete for new
clients and contracts. Our failure to meet contractual obligations could also result in substantial actual and consequential damages under
the  terms  of  such  contracts.  In  addition,  some  of  our  contracts  require  us  to  indemnify  clients  for  our  failure  to  meet  performance
standards  and/or  contain  liquidated  damages  provisions  and  financial  penalties  related  to  performance  failures. Although  we  do  have
liability insurance, the policy limits may not be adequate to provide protection against all such potential liabilities.

We have financial exposure on our fixed-price contracts because we are required to complete a project even if the costs exceed
the revenues we generate on a fixed-price contract.

We presently provide and expect to provide services under fixed-price and performance-based arrangements. Generally, under
our fixed-price contracts, we receive a specified fee regardless of our cost to perform under such contracts (compared with performance-
based contracts under which we earn fees on a per-transaction basis). If we underestimate the cost to complete a contract, we will still be
required  to  complete  the  work  specified  under  such  contract,  which  could  result  in  a  loss  to  us.  To  earn  a  profit  on  these  fixed-price
contracts,  we  must  accurately  estimate  costs  involved  and  assess  the  probability  of  meeting  the  specified  objectives,  realizing  the
expected units of work or  completing  individual  transactions,  within  the  contracted  time  period.  We  expect  to  recognize  revenues  on
these contracts, including a portion of estimated profit, as costs are incurred.

Requests for Proposals (“RFPs”) to secure government contracts are time consuming to prepare and our ability to successfully
respond to RFPs will impact our operations.

To market our services to government clients, we will likely be required to respond to Requests for Proposals (“RFPs”). To do
so effectively, we must estimate accurately our cost structure for servicing a proposed contract, the time required to establish operations
and likely terms of the proposals submitted by competitors. We must also assemble and submit a large volume of information within an
RFP’s rigid timetable. Our ability to respond successfully to RFPs will greatly impact our business. There is no assurance that we will be
awarded any contracts through the RFP process, or that our submitted RFPs will result in profitable contracts.

Some  of  our  clients  may  terminate  our  contracts  prior  to  completion,  which  could  result  in  revenue  shortfalls  and  reduce
profitability or cause losses on contracts.

Many  of  our  contracts  with  clients  contain  initial  or  base  periods  of  one  or  more  years,  as  well  as  option  periods  typically
covering more than one-half of the contract’s initial duration. However, such clients are under no obligation to exercise the option to
extend the contract term. The profitability of some of our contracts could be adversely impacted if such options are not exercised and the
contract term is not extended accordingly. Additionally, our contracts contain provisions permitting a client to terminate the contract on
short notice, with or without cause. The unexpected termination of significant contracts could result in significant revenue shortfalls. If
revenue shortfalls occur and are not offset by corresponding reductions in expenses, our business could be adversely affected. We cannot
anticipate if, when or to what extent a client might terminate its contracts with us.

17

We are subject to government audits, and our failure to comply with applicable laws, regulations and standards could subject us
to civil and criminal penalties and administrative sanctions.

The government agencies we contract with have the authority to audit and investigate our contracts with them. As part of that
process, a government agency may review our performance on a contract, our pricing practices, our cost structure and our compliance
with applicable laws, regulations and standards. If the agency determines that we have improperly allocated costs to a specific contract,
we  will  not  be  reimbursed  for  those  costs  and  we  will  be  required  to  refund  the  amount  of  any  such  costs  that  have  been  previously
reimbursed. If a government audit identifies improper activities by us or we otherwise determine that these activities have occurred, we
could be subject to civil and criminal penalties and administrative sanctions, including termination of contracts, forfeitures of profits,
suspension of payments, fines and suspension or disqualification from doing business with the government. Any adverse determination
could adversely impact our ability to bid for RFPs in one or more jurisdictions.

Unions may interfere with our ability to obtain contracts.

Our success will depend in part on our ability to win profitable contracts to administer and manage programs that may have
been  previously  administered  by  government  employees.  Many  government  employees,  however,  belong  to  labor  unions  with
considerable financial resources and lobbying networks. Unions have in the past and are likely to continue to apply political pressure on
legislators and other officials seeking to outsource government programs. Union opposition may result in fewer opportunities for us to
service government agencies.

We  rely  on  our  relationship  with  government  agencies  to  obtain  contracts,  and  there  is  no  assurance  that  we  will  be  able  to
maintain a satisfactory relationship with these agencies.

To  facilitate  our  ability  to  prepare  bids  in  response  to  RFPs,  we  expect  to  rely  in  part  on  establishing  and  maintaining
relationships with officials of various government entities and agencies. These relationships will enable us to provide informal input and
advice to the government entities and agencies prior to the development of an RFP. We also expect to engage marketing consultants,
including lobbyists, to establish and maintain relationships with elected officials and appointed members of government agencies. The
effectiveness  of  these  consultants  may  be  reduced  or  eliminated  if  a  significant  political  change  occurs.  We  may  be  unable  to
successfully manage our relationships with government entities and agencies and with elected officials and appointees and any failure to
do so may adversely affect our ability to bid successfully for RFPs.

We face significant competition in bidding for government contracts from large national and international organizations.

The government contracting industry is subject to intense competition. Many of our competitors are national and international
in  scope  and  have  greater  resources  than  we  do.  Substantial  resources  could  enable  certain  competitors  to  “low  bid”  on  government
RFPs  or  to  take  other  measures  in  an  effort  to  gain  market  share.  In  addition,  we  may  be  unable  to  compete  for  a  certain  large
government contract because we may not be able to meet an RFP’s requirement to obtain and post a large cash performance bond. Also,
in  some  geographic  areas,  we  face  competition  from  smaller  consulting  firms  with  established  reputations  and  political  relationships.
There is no assurance that we will compete successfully against our existing competitors or any new competitors.

We may not be able to effectively control and manage our growth, which would negatively impact our operations.

We  have  operated  our  current  line  of  business  for  approximately  six  years,  and  we  expect  to  grow  in  the  near  future  as  our
business develops and becomes established. If our business grows as we anticipate, it will be necessary for us to manage our expansion
in an orderly fashion. Any significant growth in our activities or in the market for our services will require extension of our managerial,
operational, marketing and other resources. Future growth will also impose significant additional responsibilities upon the members of
management to identify, recruit, maintain, integrate, and motivate new employees. Our failure to manage growth effectively may lead to
operational  inefficiencies  that  will  have  a  negative  effect  on  our  profitability. Additionally,  if  our  growth  comes  at  the  expense  of
providing  quality  service  and  generating  reasonable  profits,  our  ability  to  successfully  bid  for  contracts  and  our  profitability  will  be
adversely affected. We cannot assure investors that we will be able to effectively manage any future growth we may experience.

18

Failure to obtain adequate insurance coverage could put us at risk for uninsured losses.

We currently have liability insurance. Some or all of our customers may require insurance as a requirement to conduct business
with us. We may be unable to obtain or maintain adequate liability insurance on acceptable terms, if at all, and there is a risk that our
insurance will not provide adequate coverage against our potential losses. Additionally, there are certain types of losses that may not be
insurable at a cost that we can afford, and insurance may not be available at any cost with respect to certain losses. Claims or losses in
excess of any insurance coverage we may obtain, or the lack of insurance coverage, could put us at risk of loss for any uninsured loss,
which would have a material adverse effect on our business and financial condition.

We  are  dependent  on  our  President  and  Chief  Executive  Officer,  and  other  key  personnel,  and  the  loss  of  any  of  these
individuals could harm our business.

We depend on Mark J. Cola, our President and Chief Executive Officer, as well as key scientific and other personnel. The loss
of any of these individuals could harm our business and significantly delay or prevent the achievement of our business objectives. In
addition, our delivery of services will be labor-intensive: when we are awarded a contract, we may need to quickly hire project leaders
and  project  management  personnel.  The  additional  staff  may  also  create  a  concurrent  demand  for  increased  administrative  personnel.
The success of our business will require that we attract, develop, motivate and retain:

·
·
·

experienced and innovative executive officers;
senior managers who have successfully managed or designed programs in the public sector; and
information technology professionals who have designed or implemented complex information technology projects.

Innovative, experienced and technically proficient individuals are in great demand and are likely to remain a limited resource.
We  may  be  unable  to  continue  to  attract  and  retain  desirable  executive  officers,  senior  managers,  and  technology  professionals.  Our
inability to hire sufficient personnel on a timely basis or the loss of significant numbers of executive officers and senior managers could
adversely affect our business.

We may be dependent on cash flow and payments from customers in order to meet our expense obligations.

A  number  of  factors  may  cause  our  revenues,  cash  flow  and  operating  results  to  vary  from  quarter  to  quarter,  including  the

following:

·
·

·
·
·
·

the progression of contracts;
the  levels  of  revenues  earned  on  fixed-price  and  performance-based  contracts  (including  any  adjustments  in  expectations  for
revenue recognition on fixed-price contracts);
the commencement, completion or termination of contracts during any particular quarter;
the schedules of government agencies and large multinational corporations for awarding contracts;
the failure of our customers to fulfill their obligations under contracts with us; and
the term of awarded contracts and potential acquisitions.

Changes in the volume of activity and the number of contracts commenced, completed or terminated during any quarter may
cause  significant  variations  in  our  cash  flow  from  operations  because  a  significant  portion  of  our  expenses  are  fixed.  Fixed  expenses
include, rent, payroll, insurance, employee benefits, taxes and other administrative costs and overhead. Moreover, we expect to incur
significant  operating  expenses  during  the  start-up  and  early  stages  of  large  contracts  and  typically  do  not  receive  corresponding
payments in that same quarter.

19

We may make acquisitions in the future that we are unable to effectively manage given our limited resources.

We  may  choose  to  grow  our  business  by  acquiring  other  entities.  We  may  be  unable  to  manage  businesses  that  we  have
acquired or to integrate them successfully without incurring substantial expenses, delays or other problems that could negatively impact
our results of operations. Moreover, business combinations involve additional risks, including:

·
·
·
·
·
·
·

diversion of management’s attention;
loss of key personnel;
our becoming significantly leveraged as a result of the incurrence of debt to finance an acquisition;
assumption of unanticipated legal or financial liabilities;
unanticipated operating, accounting or management difficulties in connection with the acquired entities;
amortization of acquired intangible assets, including goodwill; and
dilution to existing stockholders and our earnings per share.

Also, client dissatisfaction or performance problems with an acquired firm could materially and adversely affect our reputation

as a whole. Further, the acquired businesses may not achieve the revenues and earnings that we anticipated.

We may be unable to develop or commercialize new and rapidly evolving technologies.

Many of our activities involve developing products or processes that are based upon new, rapidly evolving technologies. The
ability to commercialize or further develop these technologies could fail for a variety of reasons, both within and outside of our control.

We may be unable to protect our intellectual property rights.

Our success in part depends on the ability to protect our intellectual property and proprietary technology. To do so, we will be
required to prosecute patent applications and maintain patents, obtain new patents and pursue trade secret and other intellectual property
protection.  We  were  awarded  two  U.S.  patents  with  respect  to  our  munitions  technology.  We  were  also  awarded  a  U.S.  patent  with
respect to our IPQA® technology. In addition, we filed ten foreign and U.S. patent applications pertaining to our IPQA® technology and
rapid qualification of additive manufacturing for metal parts. Also, we filed a PCT patent application pertaining to the advanced dental
implant technology. However, the efforts we have taken to protect our proprietary rights may not be sufficient or effective.  There can be
no  assurance  that  our  program  for  protection  of intellectual  property  and  proprietary  technology will  be  sufficient  to  protect  our
intellectual property and proprietary technology from competitors. Our business is also subject to the risk that our issued patents will not
provide  us  with  significant  competitive  advantages  if,  for  example,  a  competitor  were  to  independently  develop  or  obtain  similar  or
superior  technologies.  In  addition,  our  issued  patents  may  be  challenged  or  infringed  upon  by  third  parties.  The  enforcement  of
intellectual  property  rights  is  subject  to  considerable  uncertainty,  and  can  be  expensive  and  time-consuming.  Patent  reform  laws  and
court decisions interpreting such laws, may create additional uncertainty around our ability to obtain and enforce patent protection. Any
significant impairment of our intellectual property rights could harm our business and our ability to compete. The unauthorized use of
our  intellectual  property  could  make  it  more  expensive  to  do  business  and  harm  our  operating  results.  Proprietary  trade  secrets  and
unpatented know-how are also very important to our business, however, trade secrets are difficult to protect. Our employees, consultants,
contractors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our confidential information to
competitors, and confidentiality agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential
or proprietary information.

We may be sued by third parties who claim that we have infringed their intellectual property rights.

We may be exposed to future litigation by third parties based on claims that our research, development and commercialization
activities  infringe  the  intellectual  property  rights  of  third  parties  to  which  we  do  not  hold  licenses  or  other  rights,  or  that  we  have
misappropriated the trade secrets of others. Any litigation or claims against us, whether or not valid, could result in substantial costs, and
could  place  a  significant  strain  on  our  financial  and  human  resources.  In  addition,  if  successful,  such  claims  could  cause  us  to  pay
substantial  damages.  Furthermore,  because  of  the  substantial  amount  of  discovery  required  in  connection  with  intellectual  property
litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation.

20

Our services are subject to government regulation, changes in which may have an adverse effect on us.

Our business activities subject us to a variety of federal, state and local laws and regulations. For example, we will required to
comply with applicable provisions of the International Traffic in Arms Regulations (“ITAR”), as well as other export controls and laws
governing  the  manufacture  and  distribution  of  munitions  technology.  Despite  the  fact  that  we  have  applied  for  and  received  ITAR
compliance, changes in the laws and regulations applicable to our business activities may have an adverse effect on our operations and
profitability by making it more expensive and less profitable for us to do business. Additionally, the market for our services depends
largely on federal and state legislative programs. These programs can be modified or amended at any time by acts of federal and state
governments. Further, if additional programs are not proposed or enacted, or if previously enacted programs are challenged, repealed or
invalidated, our growth strategy could be adversely impacted.

Our bylaws contain provisions indemnifying our officers and directors against all costs, charges, and expenses incurred by them.

Our Bylaws contain provisions with respect to the indemnification of our officers and directors against all costs, charges and
expenses, including an amount paid to settle an action or satisfy a judgment, actually and reasonably incurred by an officer or director,
including an amount paid to settle an action or satisfy a judgment in a civil, criminal or administrative action or proceeding to which he
is  made  a  party  by  reason  of  being  or  having  been  one  of  our  directors  or  officers.  To  the  extent  that  our  directors’  and  officers’
insurance  policy  does  not  provide  reimbursement  for  such  costs,  charges,  expenses  and  other  amounts,  we  may  incur  substantial
expenses in satisfying our indemnification obligations.

Our operating costs could be significantly higher than we expect, and this could reduce our future profitability.

In  addition  to  general  economic  conditions,  market  fluctuations  and  international  risks,  significant  increases  in  operating,

development and implementation costs could adversely affect us due to numerous factors, many of which are beyond our control.

A cyber incident could result in information theft, data corruption, operational disruption and/or financial loss.

Businesses have become increasingly dependent on digital technologies to conduct day-to-day operations. At the same time,
cyber incidents, including deliberate attacks or unintentional events, have increased. A cyber-attack could include gaining unauthorized
access  to  digital  systems  for  purposes  of  misappropriating  assets  or  sensitive  information,  corrupting  data,  or  causing  operational
disruption  or  result  in  denial  of  service  on  websites.  We  depend  on  digital  technology,  including  information  systems  and  related
infrastructure,  to  process  and  record  financial  and  operating  data,  and  communicate  with  our  employees  and  business  partners.  Our
technologies,  systems,  networks,  and  those  of  our  business  partners  may  become  the  target  of  cyber-attacks  or  information  security
breaches  that  could  result  in  the  unauthorized  release,  gathering,  monitoring,  misuse,  loss  or  destruction  of  proprietary  and  other
information,  or  other  disruption  of  our  business  operations. Although  to  date  we  have  not  experienced  any  losses  relating  to  cyber-
attacks, there is no assurance that we will not suffer such losses in the future. As cyber threats continue to evolve, we may be required to
expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any
information security vulnerabilities.

21

Risks Related to Our Securities

The price of our securities could be subject to volatility related or unrelated to our operations, which could result in substantial
losses for purchasers of our securities in this offering.

Between January 1, 2015 and March 31, 2017, the trading price of our common stock has ranged from a low of $0.70 to a high
of $12.40, and could be subject to wide fluctuations in the future in response to various factors, some of which are beyond our control.
The trading price of the warrants that we issued in our recent public offering could be subject to similar fluctuations as a result of such
factors. These factors include those discussed previously in this “Risk Factors” section and others, such as:

·
·
·

·

·
·
·
·
·

delays or failures in the commercialization of our current or future products and services;
quarterly variations in our results of operations or those of our competitors;
changes  in  our  earnings  estimates  or  recommendations  by  securities  analysts  or  adverse  publicity  about  us  or  our  products  or
services;
announcements  by  us  or  our  competitors  of  new  products  and  services,  significant  contracts,  commercial  relationships,
acquisitions or capital commitments;
adverse developments with respect to our intellectual property rights;
commencement of litigation involving us or our competitors;
any major changes in our board of directors or management;
market conditions in our industry; and
general economic conditions in the United States and abroad.

In  addition,  the  stock  market,  in  general,  may  experience  broad  market  fluctuations,  which  may  adversely  affect  the  market

price or liquidity of our securities.

We could be subject to securities class action litigation.

Any sudden decline in the market price of our securities could trigger securities class action lawsuits against us. If any of our
stockholders were to bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the time and attention of
our management would be diverted from our business and operations. We also could be subject to damages claims if we are found to be
at fault in connection with a decline in our market price of our securities.

An active trading market in our securities may not develop, and you may therefore have difficulty selling your securities at a
price that you determine is satisfactory.

Although  our  common  stock  and  the  2017  warrants  are  listed  on  The  NASDAQ  Capital  Market,  our  common  stock  and
warrants trade infrequently and in low volumes. The initial offering price of our securities was determined through our negotiations with
the underwriters and may not be indicative of the prices that will prevail after this offering.

There is no assurance that such securities will trade in the public market at or above the public offering price. Furthermore,
there  is  no  assurance  that  an  active  trading  market  for  any  of  our  securities  will  develop  or  be  sustained.  If  an  active  market  for  our
securities does not develop or is not maintained, it may be difficult for you to sell your securities when you wish to sell them or at a price
that you consider satisfactory. An inactive trading market may also impair our ability to raise capital to continue to fund operations by
selling securities and may impair our ability to acquire other companies or technologies by using our securities as consideration.

There is no assurance that we will satisfy the continued listing requirements of The NASDAQ Capital Market.

Even though our common stock and 2017 warrants are listed on The NASDAQ Capital Market, we cannot assure you that we
will be able to satisfy the continued listing requirements of The NASDAQ Capital Market. For example, there is no assurance that our
common stock will continue to have a bid price of at least $1.00 per share, which is the minimum bid price under such continued listing
requirements, or that we will be able to satisfy other quantitative continued listing requirements. If our securities are de-listed from The
NASDAQ Capital Market, our stockholders could incur material adverse consequences such as reduced liquidity for their securities and
reduced  market  prices  for  their  securities.  Following  such  de-listing,  we  could  encounter  increased  difficulty  in  issuing  additional
securities at an attractive price, or at all, in order to fund our operations.

22

 
You may experience additional dilution as a result of future equity offerings.

In  order  to  raise  additional  capital,  we  may  in  the  future  offer  additional  shares  of  our  common  stock  or  other  securities
convertible into or exchangeable for our common stock at prices that may not be the same as the price per unit in this offering. The price
per  share  at  which  we  sell  additional  shares  of  our  common  stock,  or  securities  convertible  or  exchangeable  into  common  stock,  in
future transactions may be lower than the price per unit paid by investors in this offering.

We have broad discretion in the use of the net proceeds of our recent public offering and may not use them effectively.

We intend to use our cash for the development of our products and service and to repay our outstanding promissory notes (if
and  to  the  extent  the  holders  thereof  demand  repayment).  We  may  also  use  a  portion  of  the  net  proceeds  from  our  February  2017
offering to acquire other products or businesses, although we are not currently a party to an agreement regarding any such acquisition.
However, our management has broad discretion in the use of cash and will have the right to use our cash in ways that differ substantially
from our current plans. Management may spend our cash in ways that do not improve our results of operations or enhance the value of
our  securities.  The  failure  by  management  to  apply  funds  effectively  could  result  in  financial  losses  that  could  have  a  material  and
adverse effect on our business and cause the market price of our securities to decline.

We do not intend to pay dividends on our common stock, and your ability to achieve a return on your investment will depend on
appreciation in the market price of our securities.

We currently intend to invest our future earnings, if any, to fund our growth and not to pay any cash dividends on our common
stock. Since we do not intend to pay dividends, your ability to receive a return on your investment will depend on any future appreciation
in the market price of our securities. There is no assurance that our securities will appreciate in price.

If  securities  or  industry  analysts  do  not  publish  research  or  reports  about  us,  or  if  they  issue  adverse  or  misleading  opinions
regarding us or our securities, the market price of our securities and their trading volume could decline.

If we do not obtain and maintain research coverage by securities and industry analysts, the market price for our securities may
be adversely affected. The market price of our securities also may decline if any analyst who covers us issues an adverse or erroneous
opinion regarding us, our business model, our intellectual property or our performance. If one or more analysts cease coverage of us or
fail  to  regularly  publish  reports  on  us,  we  could  lose  visibility  in  the  financial  markets,  which  could  cause  the  market  price  of  our
securities and their trading volume to decline and possibly adversely affect our ability to engage in future financings.

Our principal stockholders and management own a significant percentage of our common stock and will be able to significantly
affect matters subject to stockholder approval.

Based on shares outstanding as of December 31, 2016, our executive officers, directors, holders of 5% or more of our common
stock and their respective affiliates will beneficially own in the aggregate approximately 13.4% of our outstanding shares of common
stock. As a result of their stock ownership, these stockholders will have the ability to influence our management and policies, and are
able  to  significantly  affect  the  outcome  of  matters  requiring  stockholder  approval  such  as  elections  of  directors,  amendments  of  our
organizational  documents  or  approvals  of  any  merger,  sale  of  assets  or  other  major  corporate  transaction.  This  may  prevent  or
discourage unsolicited acquisition proposals or offers for our common stock that you may feel are in your best interest as one of our
stockholders.

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the
perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common
stock.  As  of  December  31,  2016,  we  have  3,133,789  outstanding  shares  of  common  stock.  Sales  of  a  large  number  of  the  shares
described in the preceding sentence, or the perception that a large number of shares may be sold, could have a material adverse effect on
the trading price of our common stock.

We will incur significant costs to ensure compliance with U.S. and NASDAQ reporting and corporate governance requirements.

We  will  incur  significant  costs  associated  with  our  public  company  reporting  requirements  and  with  applicable  U.S.  and
NASDAQ  corporate  governance  requirements,  including  requirements  under  the  Sarbanes-Oxley  Act  of  2002  and  other  rules
implemented by the SEC and NASDAQ. We expect all of these applicable rules and regulations to significantly increase our legal and
financial compliance costs and to make some activities more time consuming and costly. We also expect that these applicable rules and
regulations  may  make  it  more  difficult  and  more  expensive  for  us  to  obtain  director  and  officer  liability  insurance  and  we  may  be
required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a
result, it may be more difficult for us to attract and retain qualified individuals to serve on our board of directors or as executive officers.

If  we  fail  to  maintain  effective  internal  control  over  financial  reporting,  the  market  price  of  our  securities  may  be  adversely
affected.

As  a  public  reporting  company,  we  are  required  to  establish  and  maintain  effective  internal  control  over  financial  reporting.
Failure  to  establish  such  internal  control,  or  any  failure  of  such  internal  control  once  established,  could  adversely  impact  our  public
disclosures  regarding  our  business,  financial  condition  or  results  of  operations.  Any  failure  of  our  internal  control  over  financial
reporting could also prevent us from maintaining accurate accounting records and discovering accounting errors and financial frauds.

Rules adopted by the SEC pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 require annual assessment of our internal
control over financial reporting. The standards that must be met for management to assess the internal control over financial reporting as
effective are complex, and require significant documentation, testing and possible remediation to meet the detailed standards. We may
encounter problems or delays in completing activities necessary to make an assessment of our internal control over financial reporting. If
we  cannot  assess  our  internal  control  over  financial  reporting  as  effective,  investor  confidence  and  share  value  may  be  negatively
impacted.  In  addition,  management’s  assessment  of  internal  control  over  financial  reporting  may  identify  weaknesses  and  conditions
that  need  to  be  addressed  in  our  internal  control  over  financial  reporting  or  other  matters  that  may  raise  concerns  for  investors. Any
actual or perceived weaknesses and conditions that need to be addressed in our internal control over financial reporting (including those
weaknesses identified in our periodic reports), or disclosure of management’s assessment of our internal control over financial reporting
may have an adverse impact on the price of our securities.

Provisions  in  our  articles  of  incorporation  and  bylaws  could  discourage  a  takeover  that  stockholders  may  consider  favorable
and may lead to entrenchment of management.

Our articles of incorporation and bylaws contain provisions that could delay or prevent changes in control or changes in our

management without the consent of our board of directors. These provisions include the following:

·

·
·

·

·
·

a  classified  board  of  directors  with  three-year  staggered  terms,  which  may  delay  the  ability  of  stockholders  to  change  the
membership of a majority of our board of directors;
no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;
the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of the board of directors
or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of
directors;
the ability of our board of directors to authorize the issuance of additional shares of preferred stock and to determine the terms of
those shares, including preferences and voting rights, without stockholder approval, which could adversely affect the rights of
our common stockholders or be used to deter a possible acquisition of our company;
the ability of our board of directors to alter our bylaws without obtaining stockholder approval;
the required approval of the holders of at least two-thirds of the shares entitled to vote at an election of directors to adopt, amend
or repeal our bylaws or repeal the provisions of our articles of incorporation and bylaws regarding the election and removal of
directors;

24

·

·

·

a  prohibition  on  stockholder  action  by  written  consent,  which  forces  stockholder  action  to  be  taken  at  an  annual  or  special
meeting of our stockholders;
the requirement that a special meeting of stockholders may be called only by the chairman of the board of directors, the
chief executive officer, the president or the board of directors, which may delay the ability of our stockholders to force
consideration of a proposal or to take action, including the removal of directors; and
advance notice procedures that stockholders must comply with in order to nominate candidates to our board of directors or to
propose matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting
a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

These provisions could inhibit or prevent possible transactions that some stockholders may consider attractive.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

claims  that  arise  in  the  ordinary  course  of  our  business.  It  is  impossible  for  us  to  predict  with  any  certainty  the  outcome  of  pending
disputes,  and  we  cannot  predict  whether  any  liability  arising  from  pending  claims  and  litigation  will  be  material  in  relation  to  our
financial position or results of operations.

Dividends

We  have  not  paid  any  dividends  on  our  common  stock  to  date  and  do  not  anticipate  that  we  will  pay  dividends  in  the
foreseeable  future. Any  payment  of  cash  dividends  on  our  common  stock  in  the  future  will  be  dependent  upon  the  amount  of  funds
legally available, our earnings, if any, our financial condition, our anticipated capital requirements and other factors that the board of
directors  may  think  are  relevant.  However,  we  currently  intend  for  the  foreseeable  future  to  follow  a  policy  of  retaining  all  of  our
earnings, if any, to finance the development and expansion of our business and, therefore, do not expect to pay any dividends on our
common stock in the foreseeable future.

Recent Sales of Unregistered Securities

There  were  no  sales  by  us  of  unregistered  securities  during  the  fiscal  year  ended  December  31,  2016  other  than  those

transactions previously reported to the SEC on the Company’s quarterly reports on Form 10-Q and current reports on Form 8-K.

Repurchase of Shares

We did not repurchase any of our securities during the fiscal year ended December 31, 2016.

ITEM  7.  MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS  OF
OPERATIONS.

Critical Accounting Policies

The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States
requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  assets,  liabilities,  sales  and  expenses  in  the
accompanying financial statements. Critical accounting policies are those that require the most subjective and complex judgments, often
employing the use of estimates about the effect of matters that are inherently uncertain. Such critical accounting policies, including the
assumptions  and  judgments  underlying  them,  are  disclosed  in  Note  1  to  the  Financial  Statements  included  in  this  Annual  Report.
However, we do not believe that there are any alternative methods of accounting for our operations that would have a material effect on
our financial statements.

Results of Operations

Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015.

We expect to generate revenue primarily by selling and licensing our manufacturing and materials technologies to businesses
that seek to improve their manufacturing production processes and/or manipulate and improve the most functional characteristics of the
materials  and  other  input  components  used  in  their  business  operations.  We  also  expect  to  generate  revenues  though  contract AM
manufacturing  using  our  in-house  metal  3D  printing  capability.  However,  we  presently  make  limited  sales  of  these  technologies  and
services,  which  include  limited  sales  of  non-exclusive  licenses  to  use  our  PrintRite3D®  technologies,  including  under  our  recently
established Early Adopter Program and OEM Partner Program, as described above. Our ability to generate revenues in the future will
depend on our ability to further commercialize and increase market presence of our PrintRite3D® technologies. During the fiscal year
ended  December  31,  2016  (“fiscal  2016”),  we  generated  an  aggregate  of  $966,422  in  revenues,  as  compared  to  an  aggregate  of
$1,234,810  in  revenues  that  were  generated  by  us  during  the  fiscal  year  ended  December  31,  2015  (“fiscal  2015”).  The  decrease  in
revenue was primarily due to the completion of the GEA America Makes Program in 2016, providing only three months of revenue in
2016 (but twelve months in 2015), and the completion of the DARPA Phase II project in 2016, providing only eight months of revenue
in 2016 (but twelve months in 2015). We generated revenues and financed our operations in fiscal 2016 and fiscal 2015 primarily from
engineering consulting services we provided to third parties during these periods and through private sales of our common stock and
debt securities. We expect that our revenue will increase in future periods as we seek to further commercialize and expand our market
presence for our PrintRite3D®-related technologies, and obtain new contract manufacturing orders in connection with our EOS M290,
as  well  as  further  perform  on  our  engineering  consulting  contracts  for  the  GEA  lead  National  Additive  Manufacturing  Innovation
Institute  program,  and  continue  to  provide  our  services  under  our  contracts  with  Honeywell  Aerospace  for  the  DARPA  Period  2
program. 

In  fiscal  2016,  we  generated  an  aggregate  of  $966,422  in  revenue  from  consulting  and  other  contracts.  Specifically,  we
generated approximately (i) $893,791 in revenue in connection with our PrintRite3D®-enabled engineering consulting services, and (ii)
$72,631 in revenue in connection with our contract manufacturing activities in metal 3DP.

In  fiscal  2015,  we  generated  an  aggregate  of  $1,234,810  in  revenue  from  consulting  and  other  contracts.  Specifically,  we
generated approximately (i) $1,164,709 in revenue in connection with our PrintRite3D®-enabled engineering consulting services, and
(ii) $70,101 in revenue in connection with our contract manufacturing activities in metal 3DP.

Our other general and administrative expenses for fiscal 2016 were $1,790,096, as compared to $1,282,952 in fiscal 2015. Our
payroll  expenses  for  fiscal  2016  were  $1,026,840,  as  compared  to  $585,706  for  fiscal  2015.  Our  expenses  relating  to  non-cash
compensation for fiscal 2016 were $341,558, as compared to $518,438 for fiscal 2015. Our research and development expenses for fiscal
2016 were $92,992, as compared to $330,554 for fiscal 2015.

27

 
 
 
  
 
 
 
General and administrative expenses principally include operating expenses and outside service fees, the largest component of
which  consists  of  services  in  connection  with  our  obligations  as  an  SEC  reporting  company,  in  addition  to  other  legal,  accounting,
marketing and investor relations fees. The net increase in general and administrative expenses in fiscal 2016 as compared to fiscal 2015
is  principally  the  result  of  an  increase  in  legal  fees  in  connection  with  our  recent  public  offering,  increases  in  investor  relations
expenditures and consultant services along with our continued development of our IPQA®-enabled PrintRite3D® technologies and our
related efforts to expand our services. The net increase in payroll expenses in fiscal 2016 as compared to fiscal 2015 is principally the
result of an increase in payroll expenses from the hiring of seven additional employees. The Company incurred $341,558 of non-cash
compensation  expenses  during  2016,  $141,054  of  which  was  the  result  of  the  amortization  of  the  fair  market  value  of  the  shares  of
Company  common  stock  issued  to  our  employees  and  contractors  pursuant  to  the  Company's  2013  Equity  Incentive  Plan.  The  other
$200,504 was non-cash compensation expenses due to the vesting of outstanding stock options held by our employees pursuant to the
Company's 2013 Equity Incentive Plan.

As  a  result  of  our  increased  operating  activities,  including  as  we  seek  further  commercialization  of  our  IPQA®-enabled
PrintRite3D® technologies, and our increased marketing and sales efforts associated with such technologies, including with respect to
our EAP and OEM Partner Program, and our contract manufacturing activities, our general and administrative expenses in the future are
expected to continue to increase. Similarly, we anticipate that our payroll and non-cash compensation expenses will continue to increase
as we engage more employees and other service providers to support our efforts to grow our business.

Our  net  loss  for  fiscal  2016  increased  overall  and  totaled  $2,196,834,  as  compared  to  $1,696,282  for  fiscal  2015.  The  most
significant factor in the increase in our net loss was the result of an increase in general and administrative expense of $507,144 and an
increase in payroll expenses of $441,134, which were partially offset by other income of $317,132 primarily due to the change in the fair
value of derivative instruments, and decreases in our stock based compensation expenses and research and development expenses.

Liquidity and Capital Resources

As of December 31, 2016, we had $398,391 in cash and a working capital surplus of $110,799, as compared to $1,539,809 in

cash and a working capital surplus of $1,768,931 as of December 31, 2015.

On  February  21,  2017,  the  Company  closed  an  underwritten  public  offering  of  equity  securities  resulting  in  net  proceeds  of
approximately  $5.25  million,  after  deducting  underwriting  discounts  and  commissions  and  other  offering  expenses  payable  by  the
Company.

We expect to generate revenue primarily by licensing our manufacturing and materials technologies to businesses that seek to
improve their manufacturing production processes and/or manipulate and improve the most functional characteristics of the  materials
and other input components used in their business operations. We also expect to generate revenues by providing contract AM services
using our EOS M290 metal AM system. However, for the period from our inception through December 31, 2016, we generated revenue
and financed our operations primarily from PrintRite3D®-enabled engineering consulting services we provided during this period and
through  private  sales  of  Sigma  common  stock  and  debt  securities.  During  the  remainder  of  2017,  we  expect  to  further  ramp  up  our
operations and our commercialization and marketing efforts, which will increase the amount of cash we will use in our operations.

We  expect  that  our  continued  development  of  our  IPQA®-enabled  PrintRite3D®  technology  will  enable  us  to  further
commercialize this technology for the AM metal market in the remainder of 2017. However, until commercialization of our full suite of
PrintRite3D®  technologies,  we  plan  to  continue  funding  our  development  activities  and  operating  expenses  by  licensing  our
PrintRite3D® systems and supporting field services, as applicable, and providing PrintRite3D®-enabled engineering consulting services
concerning  our  areas  of  expertise  (materials  and  manufacturing  quality  assurance  and  process  control  technologies)  and  contract
manufacturing for metal AM, and through the use of proceeds from sales of our securities.

Cash flows used in operating activities in 2016 increased to $1,962,314 from $1,260,463 in 2015 due primarily to increases in
payroll, general and administrative costs, as well as an increase in accounts payable and a decrease in revenues in 2016,. The Company
anticipates  fewer  losses  in  2017,  due  to  increased  revenues,  offset  by  increased  salaries  and  related  expenses  in  connection  with
additional employees and potential acquisitions. Cash flows used in investing activities decreased from $161,797 in 2015 to $79,104 in
2016  primarily  due  to  fewer  purchases  of  furniture  and  equipment.  Cash  flows  provided  by  financing  activities  were  the  result  of  a
private offering of debt securities in October 2016 that raised net proceeds of $900,000. There were no cash flows used or provided by
financing activities in 2015.

We have no credit lines as of March 31, 2017, nor have we ever had a credit line since our inception.

28

 
 
 
  
 
 
 
 
Based  on  the  funds  we  have  as  of  March  31,  2017,  and  the  proceeds  we  expect  to  receive  under  our  PrintRite3D®-enabled
engineering  consulting  agreements,  from  selling  or  licensing  our  PrintRite3D®  systems  and  software,  and  sales  of  contract  AM
manufacturing for metal AM parts, we believe that we will have sufficient funds to pay our administrative and other operating expenses
through 2017. Until we are able to generate significant revenues and royalties from licensing our PrintRite3D®-enabled technologies
and our contact AM manufacturing services, our ability to continue to fund our liquidity and working capital needs will be dependent
upon revenues from existing and future PrintRite3D®-enabled engineering consulting contracts, possible strategic partnerships, contract
manufacturing orders in connection with our EOS M290, and proceeds received from sales of our debt and/or securities. Accordingly,
we may have to obtain additional capital from the sale of additional securities or by borrowing funds from lenders to fulfill our business
plans. If we issue additional equity or debt securities, stockholders may experience additional dilution or the new equity securities may
have rights, preferences or privileges senior to those of existing holders of our  common  stock.  There  is  no  assurance  that  we  will  be
successful in obtaining additional funding. If we fail to obtain sufficient funding when needed, we may be forced to delay, scale back or
eliminate all or a portion of our commercialization efforts and operations.

Inflation and changing prices have had no effect on our continuing operations over our two most recent fiscal years.

We have no off-balance sheet arrangements as defined in Item 303(a) of Regulation S-K.

ITEM 9A. CONTROLS AND PROCEDURES.

Evaluation of Disclosure Controls and Procedures

Rule 13a-15(e) under the Exchange Act defines the term “disclosure controls and procedures” as those controls and procedures
designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act
is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information
is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, or
persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Based upon an evaluation of the effectiveness of our disclosure controls and procedures performed by our management, with
the  participation  of  our  President  and  Chief  Executive  Officer,  and  Principal  Financial  and Accounting  Officer,  as  of  the  end  of  the
period  covered  by  this  annual  report,  our  management  concluded  that  our  disclosure  controls  and  procedures  are  effective  at  a
reasonable assurance level in ensuring that information required to be disclosed by us in our reports is recorded, processed, summarized
and reported within the required time periods. The foregoing conclusion is based, in part, on the fact that we are a small public company
in the early stage of our business, with limited revenues and employees.

Management’s Annual Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is
defined in Exchange Act Rule 13a-15(f) under the Exchange Act. Our management, with the participation of our President and Chief
Executive  Officer,  and  Principal  Financial  and Accounting  Officer,  conducted  an  evaluation  of  the  effectiveness  of  our  control  over
financial  reporting  based  on  the  framework  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring
Organizations of the Treadway Commission. Based on management’s evaluation under the framework, management has concluded that
our internal control over financial reporting was effective as of December 31, 2016.

29

 
 
 
  
 
 
  
 
 
  
 
  
 
 
 
 
 
 
We  continuously  seek  to  improve  and  strengthen  our  control  processes  to  ensure  that  all  of  our  controls  and  procedures  are
adequate and effective. Any failure to implement and maintain improvements in the controls over our financial reporting could cause us
to fail to meet our reporting obligations under the SEC’s rules and regulations. Any failure to improve our internal controls to address
the weakness we have identified could also cause investors to lose confidence in our reported financial information, which could have a
negative impact on the trading price of our common stock.

This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal
control over financial reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to
SEC rules that permit us to provide only management’s report in this annual report.

There  have  been  no  changes  in  our  internal  controls  over  financial  reporting  during  the  fourth  quarter  of  the  year  ended
December  31,  2016  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  our  internal  controls  over  financial
reporting.

ITEM 9B. OTHER INFORMATION

The Company will hold its annual meeting of shareholders on June 7, 2017.

On  March  27,  2017,  we  completed  funding  a  loan  in  the  principal  amount  of  $500,000  to  Morf3D  pursuant  to  a  Secured
Convertible Promissory Note dated March 27, 2017 delivered by Morf3D to us. The loan bears interest at the rate of 7% per annum, is
due and payable  in  full  on  March  27,  2018,  is  secured  by  certain  assets  of  Morf3D,  and  is  convertible  at  our  option  into  10%  of  the
outstanding  shares  of  the  common  stock  of  Morf3D  unless  Morf3D  exercises  its  right  under  specified  circumstances  to  repay  all
principal  and  accrued  interest  on  the  loan.  The  Secured  Convertible  Promissory  Note  also  contains  representations,  warranties,  and
affirmative and negative covenants of Morf3D and its principal stockholders. The purpose of the loan is to provide working capital to
Morf3D to, among other things, lease an EOS M 400 system for Morf3D for Morf3D to expand production for contracts related to AM
of high-precision aerospace & defense components, in furtherance of our strategic alliance and in contemplation of a possible acquisition
of or merger with Morf3D.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors
Sigma Labs, Inc.
Santa Fe, New Mexico

We have audited the accompanying balance sheets of Sigma Labs, Inc. as of December 31, 2016 and 2015 and the related statements of
operations,  stockholders’  equity  and  cash  flows  for  the  years  then  ended.  Sigma  Labs,  Inc.’s  management  is  responsible  for  these
financial statements. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of
material  misstatement.  The  Company  is  not  required  to  have,  nor  were  we  engaged  to  perform,  an  audit  of  its  internal  control  over
financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures
that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal
control  over  financial  reporting. Accordingly,  we  express  no  such  opinion. An  audit  includes  examining,  on  a  test  basis,  evidence
supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Sigma Labs, Inc.
as  of  December  31,  2016  and  2015  and  the  results  of  its  operations  and  its  cash  flows  for  the  years  then  ended,  in  conformity  with
accounting principles generally accepted in the United States of America.

SIGMA LABS, INC. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2016

NOTE 1 – Summary of Significant Accounting Policies

Nature of Business  –  On  September  13,  2010  Sigma  Labs,  Inc.,  formerly  named  Framewaves,  Inc.,  a  Nevada  corporation,  acquired
100%  of  the  shares  of  B6  Sigma,  Inc.  by  exchanging  6.67  shares  of  Framewaves,  Inc.  restricted  common  stock  for  each  issued  and
outstanding share of B6 Sigma, Inc. The acquisition has been accounted for as a “reverse purchase,” and accordingly the operations of
Framewaves, Inc. prior to the date of acquisition have been eliminated. Unless otherwise indicated or the context otherwise requires, the
term  “B6  Sigma”  refers  to  B6  Sigma,  Inc.,  a  Delaware  corporation,  which,  until  the  short-form  merger  referenced  below,  was  our
wholly-owned,  operating  company  acquired  in  September  2010;  the  terms  the  “Company,”  “Sigma,”  “we,”  “us”  and  “our”  refer  to
Sigma Labs, Inc., together with B6 Sigma, Inc. Prior to December 29, 2015, we conducted substantially all of our operations through B6
Sigma. On December 29, 2015, we completed a short-form merger of B6 Sigma into Sigma. As a result, B6 Sigma became part of Sigma
and no longer exists as a subsidiary.

B6  Sigma,  Inc.,  incorporated  February  5,  2010,  was  founded  by  a  group  of  scientists,  engineers  and  businessmen  to  develop  and
commercialize novel and unique manufacturing and materials technologies. The Company believes that some of these technologies will
fundamentally  redefine  conventional  quality  assurance  and  process  control  practices  by  embedding  them  into  the  manufacturing
processes in real time, enabling process intervention and ultimately leading to closed loop process control. The Company anticipates that
its core technologies will allow its clientele to combine advanced manufacturing quality assurance and process control protocols with
novel materials to achieve breakthrough product potential in many industries including aerospace, defense, oil and gas, bio-medical, and
power generation.

Basis of Presentation – The accompanying financial statements have been prepared by the Company in accordance with Article 8 of
U.S. Securities and Exchange Commission Regulation S-X. In the opinion of management, all adjustments (which include only normal
recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at December 31, 2016 and
2015 and for the periods then ended have been made.

Reclassification – Certain amounts in prior-period financial statements have been reclassified for comparative purposes to conform to
presentation in the current-period financial statements.

Loss Per Share – The computation of loss per share is based on the weighted average number of shares outstanding during the period in
accordance with ASC Topic No. 260, “Earnings Per Share.”

Property and Equipment – Property and equipment are stated at cost. Expenditures for major renewals and betterments that extend the
useful  lives  of  property  and  equipment  are  capitalized  upon  being  placed  in  service.  Expenditures  for  maintenance  and  repairs  are
charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. The
estimated  life  has  been  determined  to  be  three  years  unless  a  unique  circumstance  exists,  which  is  then  fully  documented  as  an
exception to the policy.

Fair Value of Financial Instruments - The Company applies ASC 820, “Fair Value Measurements.” This guidance defines fair value,
establishes  a  three-level  valuation  hierarchy  for  disclosures  of  fair  value  measurement  and  enhances  disclosure  requirements  for  fair
value measures. The three levels are defined as follows:

·

·

·

Level 1 inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs
that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument.

Level 3 inputs to valuation methodology are unobservable and significant to the fair measurement.

Fair Value of Financial Instruments  –  The  Company  adopted ASC  820, Fair  Value  Measurements  and  Disclosures,  for  assets  and
liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing
US  GAAP  that  requires  the  use  of  fair  value  measurements  which  establishes  a  framework  for  measuring  fair  value  and  expands
disclosure about such fair value measurements.

F-7

 
 
 
 
 
ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the
use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below:

Level 1:
Level 2:
Level 3:

Observable inputs such as quoted market prices in active markets for identical assets or liabilities
Observable market-based inputs or unobservable inputs that are corroborated by market data
Unobservable  inputs  for  which  there  is  little  or  no  market  data,  which  require  the  use  of  the  reporting  entity’s  own
assumptions.

The carrying amounts reported in the balance sheets for the cash and cash equivalents, prepaid stock compensation, receivables accounts
payable,  and  accrued  liabilities  each  qualify  as  financial  instruments  and  are  a  reasonable  estimate  of  fair  value  because  on  the  short
period of time between the origination of such instruments and their expected realization and their current market rate of interest.

In addition, FASB ASC 825-10-25, Fair Value Option was effective for January 1, 2008. ASC 825-10-25 expands opportunities to use
fair value measurements in financial reporting and permits entities to choose to measure many financial instruments and certain other
items at fair value.

Fair value of financial instruments is as follows:

December 31, 2016

The  derivative  liability  is  the  result  of  the  $1  million  of  Notes,  and  the  160,000  warrants,  that  were  issued  in  October  2016,  both  of
which contain anti-dilution provisions in  the  event  the  Company  engages  in  specified  transactions.  The  Notes  mature  on  October  17,
2017 and the warrants expire on October 17, 2019. The following table presents a reconciliation of the derivative liability measured at
fair value on a recurring basis using significant unobservable input (Level 3) on October 17, 2016 and December 31, 2016:

At  December  31,  2015,  the  Company  had  two  outstanding  warrants  to  purchase  a  total  of  12,500  shares  of  common  stock  but  the
warrants  did  not  contain  anti-dilution  provisions,  and  thus  were  not  derivative  liabilities.  The  fair  value  of  one  of  the  warrants  of
$271,250  was  expensed  on  the  date  of  issuance  in  2014,  and  was  calculated  using  a  Black-Scholes  option  pricing  model  with  the
following  assumptions:  expected  life  of  two  years,  expected  volatility  of  201%,  a  risk-free  interest  rate  of  0.39%,  and  an  expected
dividend yield of 0%. The fair value of the other warrant of $36,250 was expensed on the date of issuance in 2014, and was calculated
using a Black-Scholes option pricing model with the following assumptions: expected life of two years, expected volatility of 287%, a
risk-free interest rate of 0.41%, and an expected dividend yield of 0%.

Income Taxes – The Company accounts for income taxes in accordance with ASC Topic No. 740, “Accounting for Income Taxes.”

The Company adopted the provisions of ASC Topic No. 740, “Accounting for Income Taxes,” at the date of inception on February 5,
2010. As a result of the implementation of ASC Topic No. 740, the Company recognized no increase in the liability for unrecognized tax
benefits.

The Company has no tax positions at December 31, 2016 and 2015 for which the ultimate deductibility is highly certain but for which
there is uncertainty about the timing of such deductibility.

The Company recognizes interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses.
During the year ended December 31, 2016, the Company recognized no interest and penalties. The Company had no accruals for interest
and penalties at December 31, 2016 or 2015. All tax years starting with 2010 are open for examination.

Loss Per Share – The computation of loss per share is based on the weighted average number of shares outstanding during the period in
accordance with ASC Topic No. 260, “Earnings Per Share.”

Accounts Receivable and Allowance for Doubtful Accounts - Trade accounts receivable are carried at original invoice amount less an
estimate made for doubtful accounts. We determine the allowance for doubtful accounts by identifying potential troubled accounts and
by using historical experience and future expectations applied to an aging of accounts. Trade accounts receivable are written off when
deemed uncollectible. Recoveries of trade accounts receivable previously written off are recorded as income when received. There no
allowance for doubtful accounts at December 31, 2016 or 2015.

Long-Lived  and  Intangible Assets  –  Long-lived  assets  and  certain  identifiable  definite  life  intangibles  to  be  held  and  used  by  the
Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may
not be recoverable. The Company continuously evaluates the recoverability of its long-lived assets based on estimated future cash flows
and  the  estimated  liquidation  value  of  such  long-lived  assets,  and  provides  for  impairment  if  such  undiscounted  cash  flows  are
insufficient to recover the carrying amount of the long-lived assets. If impairment exists, an adjustment is made to write the asset down
to its fair value, and a loss is recorded as the difference between the carrying value and fair value. Fair values are determined based on
quoted market values, discounted cash flows or internal and external appraisals, as applicable. Assets to be disposed of are carried at the
lower of carrying value or estimated net realizable value. No impairment was recorded in the years ended December 31, 2016 or 2015.

Recently Enacted Accounting Standards – The FASB established the Accounting Standards Codification (“Codification” or “ASC”)
as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation
of  financial  statements  in  accordance  with  generally  accepted  accounting  principles  in  the  United  States  (“GAAP”).  Rules  and
interpretive  releases  of  the  Securities  and  Exchange  Commission  (“SEC”)  issued  under  authority  of  federal  securities  laws  are  also
sources of GAAP for SEC registrants.

Recent Accounting Standards Updates (“ASU”) through ASU No. 2015-01 contain technical corrections to existing guidance or affects
guidance  to  specialized  industries  or  situations.  The  Company  has  evaluated  recently  issued  technical  pronouncements  and  has
determined that these updates have no current applicability to the Company or their effect on the financial statements would not have
been significant.

Cash Equivalents - The Company considers all highly liquid investments with an original maturity of three months or less at date of
purchase to be cash equivalents.

Concentration  of  Credit  Risk  -  The  Company  maintains  its  cash  in  bank  deposit  accounts,  which,  at  times,  may  exceed  federally
insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk
on cash and cash equivalents.

Organization Expenditures – Organizational expenditures are expensed as incurred for SEC filings, but capitalized and amortized for
income tax purposes.

Stock Based Compensation – The Company recognizes compensation costs to employees under ASC Topic No. 718, “Compensation –
Stock  Compensation.”  Under  ASC  Topic  No.  718,  companies  are  required  to  measure  the  compensation  costs  of  share-based
compensation arrangements based on the grant-date fair value and recognize the costs in the financial statements over the period during
which employees are required to provide services. Share based compensation arrangements may include stock options, grants of shares
of common stock with and without restrictions, performance based awards, share appreciation rights and employee share purchase plans.
As such, compensation cost is measured on the date of grant at its fair value. Such compensation amounts, if any, are amortized over the
respective vesting periods of the option or stock grants. Unvested option or stock grants for compensation are included in the Statement
of Stockholders’ Equity as a contra-equity account as “Deferred Compensation.”

F-9

 
 
 
 
 
 
 
 
Equity instruments issued to non-employees are recorded on the basis of the fair value of the instruments, as required by ASC Topic No.
505, “Equity Based Payments to Non-Employees.” In general, the measurement date is either (a) when a performance commitment, as
defined, is reached or (b) the earlier of the date that (i) the non-employee performance requirement is complete or (ii) the instruments are
vested. The measured value related to the instruments is recognized over a period based on the facts and circumstances of each particular
grant as defined in the FASB Accounting Standards Codification.

Amortization - Utility patents are amortized over a 17 year period. Patents which are pending are not amortized.

Accounting Estimates  -  The  preparation  of  financial  statements  in  conformity  with  generally  accepted  accounting  principles  in  the
United States requires management to make estimates and assumptions that affect certain reported amounts of assets and liabilities, the
disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimated by management. Significant accounting estimates that may
materially  change  in  the  near  future  are  impairment  of  long-lived  assets,  values  of  stock  compensation  awards  and  stock  equivalents
granted as offering costs, and allowance for bad debts and inventory obsolescence.

Revenue  Recognition  –  The  Company’s  revenue  is  derived  primarily  from  providing  services  under  contracts.  The  Company
recognizes  revenue  in  accordance  with ASC  Topic  No.  605  based  on  the  following  criteria:  Persuasive  evidence  of  an  arrangement
exists, services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. In general, the Company
recognizes service revenue as significant services under the relevant arrangement have been performed.

Deferred Stock Offering Costs – Costs related to stock offerings (if any) are deferred and will be offset against the proceeds of the
offering in additional paid-in capital. In the event a stock offering is unsuccessful, the costs relating to the offering will be written-off
directly to expense.

Inventory  –  Inventories  consist  of  raw  materials  used  in  the  production  of  customized  parts  totaling  $187,241  and  $20,129,  as  of
December 31, 2016 and 2015, respectively, and nominal work-in-process components which will be sold to customers. Inventories are
valued at the lower of cost or market, using the first-in, first-out (FIFO) method.

Research and Development – Research and development costs are expensed as they are incurred. Research and development costs for
the years ended December 31, 2016 and 2015 were $92,992 and $330,554, respectively.

Stock Options

On April 28, 2016, at the Annual Meeting of Stockholders of the Company, the Company's stockholders approved an amendment to the
2013  Plan  to  increase  the  number  of  shares  of  the  Company's  common  stock  reserved  for  issuance  under  the  2013  Plan  by  319,269
shares of our common stock to a total of 375,000 shares (on a post-Reverse Stock Split basis). As of December 31, 2016, an aggregate
of 750 shares and 199,669 shares of common stock were reserved for issuance under the 2011 Plan and the 2013 Plan, respectively.

During 2016, the Company granted a total of 73,688 options to 10 employees with vesting periods ranging from 3 to 4 years beginning
March  14,  2017.  In  2016,  2,938  options  vested,  and  $168,411  of  compensation  cost  had  been  recognized  during  the  year.  As  of
December 31, 2016, there were options to purchase 101,188 shares outstanding under the plans. Of this amount, there are vested options
exercisable into 2,938 shares of common stock. As of December 31, 2016, the Company had 200,419 shares reserved for future grant

beginning  August  10,  2015.  As  of  December  31,  2015,  none  of  the  option  grants  had  vested,  and  only  a  nominal  amount  of
compensation cost had been recognized during the year. The weighted average period over which total compensation cost of the options
of $306,796 will be recognized is 3.81 years. The weighted average exercise price of the options was $11.88 and the weighted average
fair value of the options on the dates of grant was $11.82.

The  Company  generally  grants  stock  options  to  employees  and  directors  at  exercise  prices  equal  to  the  fair  market  value  of  the
Company's  stock  on  the  dates  of  grant.  Stock  options  are  typically  granted  throughout  the  year  and  generally  vest  over  four  years  of
service and expire ten years from the date of the award, unless otherwise specified. The Company recognizes compensation expense for
the fair value of the stock options over the requisite service period for each stock option award.

Total share-based compensation expense included in the consolidated statements of operations for the years ended December 31, 2016
and 2015 is $341,558 and $518,438, respectively. There was no capitalized share-based compensation cost as of December 31, 2016 and
2015, and there were no recognized tax benefits during the years ended December 31, 2016 and 2015.

To  estimate  the  value  of  an  award,  the  Company  uses  the  Black-Scholes  option-pricing  model.  This  model  requires  inputs  such  as
expected  life,  expected  volatility  and  risk-free  interest  rate.  The  forfeiture  rate  also  impacts  the  amount  of  aggregate  compensation.
These  inputs  are  subjective  and  generally  require  significant  analysis  and  judgment  to  develop.  While  estimates  of  expected  life,
volatility and forfeiture rate are derived primarily from the Company’s historical data, the risk-free rate is based on the yield available on
U.S. Treasury constant maturity rates with similar terms to the expected term of the stock option awards. The fair value of share-based
awards was estimated using the Black-Scholes model with the following weighted-average assumptions for the years ended December
31, 2016 and 2015:

Assumptions:

Dividend yield
Risk-free interest rate

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying awards and the quoted price of
our  common  stock  for  those  awards  that  have  an  exercise  price  currently  below  the  $3.24  closing  price  of  our  Common  Stock  on
December 31, 2016. None of the options have an exercise price currently below $3.24.

At December 31, 2016 and 2015, there was $452,551 and $619,300, respectively, of unrecognized share-based compensation expense
related to unvested share options with a weighted average remaining recognition period of 9.29 and 9.65 years, respectively.

Warrants

At December 31, 2016, the Company had two outstanding warrants to purchase a total of 80,000 shares of common stock at an exercise
price of $8.10 per share. If not exercised, the warrants to purchase 80,000 shares will expire on October 17, 2019.

At December 31, 2015, the Company had two outstanding warrants to purchase a total of 12,500 shares of common stock at an exercise
price of $16.00 per share. Warrants to purchase 10,938 shares expired on January 10, 2016 and warrants to purchase 1,563 expired on
June 4, 2016.

During  the  year  ended  December  31,  2015,  a  warrant  to  purchase  10,186  shares  of  common  stock  at  an  exercise  price  of  $30.00  per
share as well as a warrant to purchase 71,297 shares of common stock at an exercise price of $30.00 per share expired.

NOTE 3 – Notes Payable

Effective October 17, 2016, the Company entered into a Securities Purchase Agreement with two accredited investors (the “Investors”)
for the private placement by the Company of Secured Convertible Notes in the aggregate principal amount of $1,000,000 (the "Notes")
and  warrants  (the  "Warrants")  to  purchase  up  to  80,000  shares  (the  "Warrant  Shares")  of  the  Company's  common  stock  ("Common
Stock") (subject to adjustment in certain circumstances), for aggregate gross proceeds, before expenses, to the Company of $900,000 (the
“Financing Transaction”).

The Notes carry a one-time upfront interest charge of a total of $100,000, which is being expensed to interest expense monthly over the
1-year term of the Notes and correspondingly increases in the Notes Payable balance each period. As of December 31, 2016, the Notes
Payable balance is $920,114. However, the effective Notes Payable balance is $1 million since that is the amount we would have to pay
in order to payoff the note anytime between now and the maturity date of October 17, 2017, in addition to accrued interest and a 15%
pre-payment penalty.

The Notes carry an interest rate of 10% per annum, calculated on the basis of a 360-day year, based on the $1 million Notes Payable
effective  balance.  Such  interest  is  payable  every  three  months  in  cash,  or,  at  the  holder’s  option,  in  unrestricted  shares  of  Common
Stock, if a registration statement is then in effect for such shares of common stock.

In connection with the Financing Transaction, the Company entered into a Registration Rights Agreement, dated October 17, 2016, with
the Investors (the “Registration Rights Agreement”), pursuant to which the Company agreed to file a registration statement related to the
Financing Transaction with the Securities and Exchange Commission (“SEC”) covering the resale of (i) the shares of Common Stock
that  will  be  issued  to  the  Investors  upon  conversion  of  the  Notes  (the  "Conversion  Shares"),  and  (ii)  the  Warrant  Shares  that  will  be
issued  to  the  Investors  upon  exercise  of  the  Warrants.  The  Notes  are  secured  by  the  assets  of  the  Company  pursuant  to  a  Security
Agreement, dated October 17, 2016, between the Company and the "collateral agent" (as defined in the Notes) for the benefit of itself
and each of the Investors.

The  Notes  are  convertible  into  shares  of  Common  Stock  at  a  conversion  price  equal  to  the  lesser  of  (i)  the  final  unit  price  of  the
Company’s proposed public offering initially filed with the SEC on July 28, 2016, and (ii) 150% of the closing price of the Common
Stock as reported by the OTC Markets Group, Inc. on the date of issuance of the Notes (subject to adjustment as provided therein). As
such, as of December 31, 2016, the conversion price of the Notes was $8.10, which is 150% of the closing price of the Common Stock
as reported by the OTC Markets Group, Inc. on the date of issuance.

Each  Warrant  has  an  initial  exercise  price  equal  to  the  lesser  of  (i)  the  final  unit  price  of  the  Company’s  proposed  public  offering
initially filed with the SEC on July 28, 2016, and (ii) 150% of the closing price of the Common Stock as reported by the OTC Markets
Group, Inc. on the date of issuance of the Warrants (subject to adjustment as provided therein), which Warrants may be exercised on a
cashless basis as provided in the Warrants. As such, as of December 31, 2016, the exercise price of the Warrants was $4.05, which is
150% of the closing price of the Common Stock as reported by the OTC Markets Group, Inc. on the date of issuance.

NOTE 4 – Continuing Operations

The Company has sustained losses and has negative cash flows from operating activities since its inception. However, the Company has
had increasing revenues in recent periods. In addition, the Company has raised significant equity capital and is currently securing new
product  lines  to  increase  future  revenues.  On  February  21,  2017,  the  Company  closed  an  underwritten  public  offering  of  equity
securities resulting in net proceeds of approximately $5.25 million, after deducting underwriting discounts and commissions and other
offering expenses payable by the Company. As such, the Company believes it has adequate working capital and cash to fund operations
through 2017, and has entered into significant revenue contracts that are expected to generate cash flow in the near term.

NOTE 5 – Income Taxes

The Company accounts for income taxes in accordance with ASC Topic No. 740. This standard requires the Company to provide a net
deferred tax asset or liability equal to the expected future tax benefit or expense of temporary reporting differences between book and tax
accounting methods and any available operating loss or tax credit carryforwards. Income tax returns open for examination by the Internal
Revenue Service consist of tax years ended December 31, 2012 through 2014.

The Company has available at December 31, 2016, unused operating loss carryforwards of approximately $8,328,160, which may be
applied against future taxable income and which expire in various years through 2035. However, if certain substantial changes in the
Company’s ownership should occur, there could be an annual limitation on the amount of net operating loss carryforward which can be
utilized.  The  amount  of  and  ultimate  realization  of  the  benefits  from  the  operating  loss  carryforwards  for  income  tax  purposes  is
dependent, in part, upon the tax laws in effect, the future earnings of the Company and other future events, the effects of which cannot
be  determined.  Because  of  the  uncertainty  surrounding  the  realization  of  the  loss  carryforwards,  the  Company  has  established  a
valuation allowance equal to the tax effect of the loss carryforwards and other temporary differences of approximately $3,767,996 and
$2,914,526  at  December  31,  2016  and  2015,  respectively,  and,  therefore,  no  deferred  tax  asset  has  been  recognized  for  the  loss
carryforwards. The change in the valuation allowance is approximately $853,470 and $659,006 for the years ended December 31, 2016
and 2015, respectively.

Deferred tax assets are comprised of the following:

NOTE 8 – Intangible Assets

The Company’s intangible assets consist of Patents, Patent Pending Applications and Customer Contacts.

Provisional patent applications are not amortized until a patent has been granted. Once a patent is granted, the Company will amortize
the related costs over the estimated useful life of the patent. If a patent application is denied, then the costs will be expensed at that time.

The  customer  contacts  were  acquired  in  a  business  acquisition  on  December  31,  2011  and  were  to  be  amortized  over  their  estimated
useful life of 3 years.

NOTE 11 - Joint Venture

As previously reported in our Form 8-K filed with the SEC on July 6, 2015, we entered into an Operating Agreement and Statement of
Work  with Arete  Innovative  Solutions  LLC  (“Arete”).  The  Operating Agreement  and  Statement  of  Work  governed  the  operations  of
Arete-Sigma  LLC  (the  "Joint  Venture"),  a  joint  venture  formed  by  us  and Arete  for  the  purpose  of  pursuing  business  opportunities
related  to AM  utilizing  our  EOS  M290  or  like  machines,  including  enabling  and  implementing  sales  and  manufacturing  transactions.
Under the Operating Agreement and Statement of Work, among other matters reported in our Form 8-K and set forth in the Operating
Agreement and Statement of Work, (i) each of Sigma and Arete held a 50% ownership interest in the Joint Venture, and (ii) the Joint
Venture was managed by William F. Herman, President of Arete, subject to certain limitations. Based on the Operating Agreement, the
Company  held  the  non-controlling  interest  in  the  Joint  Venture.  Therefore,  the  Joint  Venture  was  not  consolidated,  but  rather  was
accounted  for  on  the  equity  method  of  recording  investments.  During  the  years  ended  December  31,  2016  and  2015,  net  operations
resulted  in  a  loss  on  the  investment  of  $105  and  $778,  respectively.  The  Company  terminated  the  Joint  Venture  in  2016,  but  is
continuing to pursue business opportunities related to AM utilizing the Company's EOS M290 or like machines.

Note 12 - Defined Contribution Plan

In 2014, the Company adopted a qualified 401(K) plan (Plan), in which all employees over the age of 21 may participate. The Company
has elected to match 100% of each participant’s contribution up to 3% of salary, and 50% of the next 2% of salary contributed. The
Company  may  also  elect,  on  an  annual  basis,  to  make  a  discretionary  contribution  to  the  plan.  Company  matches  and  elective
contributions vest to participant accounts as follows: 20% after two years of service, and 20% per year thereafter until the participant
reaches 6 years of service, at which time, employer contributions vest 100%. The cost of matching contributions were $35,488 in 2016
and $18,315 in 2015.

NOTE 13 – Subsequent Events

In connection with their appointment to the Company’s Board of Directors, on January 10, 2017, the Company granted each of Sam Bell
and Frank Garofalo 5,000 shares of common stock of the Company, under the Company’s 2013 Equity Incentive Plan, with such shares
to vest in four equal, successive quarterly installments of 1,250 shares each, beginning on April 10, 2017, subject to the requirement that
each of Messrs. Bell and Garofalo, as applicable, must remain a director of the Company.

Effective February 15, 2017, our Amended and Restated Articles of Incorporation were amended pursuant to a Certificate of Change
Pursuant to Nevada Revised Statutes 78.209 (the “Certificate of Change”) filed with the Nevada Secretary of State. The Certificate of
Change provided for both a reverse stock split of the outstanding shares of our common stock on a 1-for-2 basis (the “Reverse Stock
Split”),  and  a  corresponding  decrease  in  the  number  of  shares  of  our  common  stock  that  we  are  authorized  to  issue  (the  “Share
Decrease”).

As a result of the Reverse Stock Split, the number of issued and outstanding shares of our common stock decreased from 6,307,577 pre-
Reverse  Stock  Split  shares  to  3,153,801  post-Reverse  Stock  Split  shares  (after  adjustment  for  any  fractional  shares).  Pursuant  to  the
Share  Decrease,  the  number  of  authorized  shares  of  our  common  stock  decreased  from  15,000,000  to  7,500,000  shares  of  common
stock, $0.001 par value per share.

On February 21, 2017, the Company closed an underwritten public offering of 1,410,000 units, with each unit consisting of one share of
the Company's common stock and one warrant to purchase one share of common stock. The underwriter exercised the over-allotment
option covering additional warrants to purchase up to 211,500 additional shares of common stock.

F-17

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
 
Gross proceeds to the Company from the offering, including the exercise of the over-allotment option, were approximately $5.8 million,
before  deducting  underwriting  discounts  and  commissions  and  other  offering  expenses  payable  by  the  Company.  Dawson  James
Securities, Inc. acted as the sole underwriter for the offering.

The  shares  and  warrants  described  above  were  offered  by  Sigma  Labs  pursuant  to  a  registration  statement  previously  filed  with  and
subsequently declared effective by the Securities and Exchange Commission ("SEC"). A final prospectus relating to the offering was
filed with the SEC and is available on the SEC's website at http://www.sec.gov, or by contacting Dawson James: 1 N. Federal Hwy;
Suite 500, Boca Raton, FL 33432, ATTN: Prospectus Department.

On February 14, 2017, in connection with the offering, The NASDAQ Stock Market LLC informed the Company that it had approved
the  listing  of  the  Company’s  common  stock  and  warrants  on  The  NASDAQ  Capital  Market,  effective  as  of  February  15,  2017  (the
"Listing"). The Company’s common stock ceased trading on the OTCQB on February 15, 2017, and on such date the common stock and
the above described warrants commenced trading on The NASDAQ Capital Market under the ticker symbols “SGLB” and “SGLBW,”
respectively.

On February 15, 2017, in conjunction with John Rice's appointment as a director of the Company, the Company issued Mr. Rice 5,231
shares  of  common  stock,  which  shares  will  vest  in  four  equal,  successive  quarterly  installments  beginning  on  the  first  quarterly
anniversary of the grant date, provided that an installment will not vest if Mr. Rice is not a director of the Company as of the applicable
quarterly anniversary date.

On  February  16,  2017,  the  Company  and  Mark  J.  Cola  entered  into  an  employment  agreement  (the  "Employment Agreement")  for  a
three-year  term,  pursuant  to  which  Mr.  Cola  will  continue  to  serve  as  the  Company’s  President,  Chief  Executive  Officer  and  Chief
Operating Officer. The Employment Agreement became effective as of the closing of the public offering described above. Under the
Employment Agreement,  Mr.  Cola  is  entitled  to  receive  an  annual  base  salary  of  $220,000,  which  will  be  subject  to  increase  in  the
discretion of the board of directors or Compensation Committee based on its annual assessment of Mr. Cola’s performance and other
factors. Pursuant to the Employment Agreement, the Company granted Mr. Cola a stock option to purchase up to 123,750 shares of our
common stock under the Company's 2013 Equity Incentive Plan, as amended, vesting in equal quarterly installments over an 18-month
period. The Company agreed in the Employment Agreement that, on each of the first and second anniversaries of the effectiveness of the
Employment Agreement, Mr. Cola will receive a stock option to purchase 61,875 shares of our common stock. Each stock option will
have an exercise price equal to the closing price of our common stock on the date of grant and will vest and become exercisable in equal
quarterly  installments  over  an  18-month  period,  provided,  in  each  case,  that  Mr.  Cola  remains  an  employee  of  the  Company  through
such vesting date.

On March 27, 2017, we completed funding a loan in the principal amount of $500,000 to Morf3D pursuant to a Secured Convertible
Promissory  Note  dated  March  27,  2017  delivered  by  Morf3D  to  us.  The  loan  bears  interest  at  the  rate  of  7%  per  annum,  is  due  and
payable in full on March 27, 2018, is secured by certain assets of Morf3D, and is convertible at our option into 10% of the outstanding
shares  of  the  common  stock  of  Morf3D  unless  Morf3D  exercises  its  right  under  specified  circumstances  to  repay  all  principal  and
accrued interest on the loan. The Secured Convertible Promissory Note also contains representations, warranties, and affirmative and
negative covenants of Morf3D and its principal stockholders. The purpose of the loan is to provide working capital to Morf3D to, among
other things, lease an EOS M 400 system for Morf3D for Morf3D to expand production for contracts related to AM of high-precision
aerospace & defense components, in furtherance of our strategic alliance and in contemplation of a possible acquisition of or merger
with Morf3D.
