Summary We are a technology company that specializes in the development and commercialization of novel and unique manufacturing and materials technologies. It is the Company's belief that some of these technologies will fundamentally redefine conventional quality assurance and control practices by embedding quality assurance and process control into the manufacturing process in real time. In addition, the Company anticipates that its core technologies will enable its clientele to combine advanced manufacturing quality assurance and control protocols with novel materials to achieve breakthrough product potential in many industries including aerospace, defense, oil and gas, bio-medical and power generation. Certain members of our team are uniquely qualified scientists with broad backgrounds in manufacturing and materials technologies. In the past, these members have worked with some of the largest defense contractors in the world, in such varied projects as next-generation manufacturing systems, advanced reactive munitions, nuclear weapons stewardship programs, and naval nuclear reactor programs. Our current business plan and principal business activities include the continued development of our In-Process Quality Assurance™ (IPQA®) suite of technologies and the commercialization of both our IPQA® and materials-related suite of technologies, with our main focus currently on the 3D Printing ("3DP") industry and making operational the contract manufacturing business for metal 3DP, which technologies are described elsewhere in this Annual Report on Form 10-K. Our strategy is to leverage our manufacturing and materials knowledge, experience and capabilities through the following means: (i) identify, develop and commercialize manufacturing and materials technologies designed to improve manufacturing and quality control practices, and create innovative products in a variety of industries; (ii) provide engineering consulting services in respect of our manufacturing and materials technology expertise to third parties that have needs in developing next-generation technologies for materials and manufacturing projects; and (iii) build and run a contract manufacturing division for metal 3DP beginning with our Electro Optical Systems (EOS) GmbH M290 DMLS® (Direct Metal Laser Sintering) ("EOS M290") state-of-the-art metal printer. We are presently engaged in a variety of activities in which we seek to commercialize technologies and products in the following industry sectors: 1 · · · · · Aerospace and defense manufacturing; Oil & Gas and Energy manufacturing; Bio-medical manufacturing; Automotive manufacturing; and Other markets such as firearms and recreational equipment. We expect to generate revenues primarily by direct sales and software licensing of 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. Additionally, we expect to generate additional revenues from our contract manufacturing activities in metal 3DP. We also expect that our continued development of our “In Process Quality Assurance™” or “IPQA® technology will enable us to finalize our commercialization of this technology for the AM metal market in the remainder of 2016. We plan to assist our commercialization partners with marketing-related activities for those advanced material-related technologies, including our dental implant biomedical prosthetics technology, for which we seek possible commercialization in the future. However, we presently make no sales of our dental implant biomedical prosthetics technology. Our board of directors, management and business advisors comprise scientists and business professionals with extensive experience in the energy and advanced manufacturing and materials technology markets, as well as business operations. These individuals collectively possess over 100 years of experience working in the advanced manufacturing, materials technology and commercial industry space. As such, we believe we possess the resident expertise to provide engineering services and support to companies using our IPQA® software solutions for metal AM. Accordingly, in addition to our primary business focus, we intend to generate revenues by providing such engineering services and support to businesses licensing our IPQA® software technologies. 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 20 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. The Company acquired Sumner & Lawrence Limited (dba Sumner Associates) in December 2011. Sumner Associates was a private consulting company that provided services to the public and private sector. Sumner Associates was dissolved during fiscal 2014 as the number of its contracts had been reduced due to, among other things, changing funding climates within the DOE. EARLY STAGE TECHNOLOGY COMMERCIALIZATION AND MARKET POSITIONING Since our inception, we have made tremendous progress in bringing early stage technology from scientific concept and curiosity to practical reality, as described below. 1. In-Process Quality Assurance™ (IPQA®) for Additive Manufacturing. We believe that "additive manufacturing" ("AM"), also known as 3D Printing, will significantly impact the manufacturing landscape and revolutionize 21st century industry. 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 digital computer designs and 3D computer models to actual, physical parts in a single step. 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 currently a “black art” with limited applications, Sigma is developing its IPQA® technology into a breakthrough hardware and software suite of products for AM known as PrintRite3D®, which we expect will fully address some these shortcomings and enable serial 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 software modules 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. 2 2. Contract Manufacturing for Metal Additive Manufacturing. According to the Wohlers 2015 Annual Report, the service provider segment, industry growth in 2014 was an estimated $2.105 billion, an increase of 38.9% from $1.516 billion in 2013. This market segment grew by 26.3% in 2013, 36.4% in 2012, and 30.7% in 2011. Contract manufacturers are still in the early stages of adding metal AM systems to supply production parts to aerospace and industrial original equipment manufacturers ("OEMs"), such as GE Aviation ("GEA") and Honeywell Aerospace. We believe that most AM machines produced through 2014 are still not well suited for production applications. They have limited feedback measurement and control sensors to guarantee part quality. Some of the latest machines available, such as EOS’s M290 machine, are beginning to be sold with limited advanced measurement system capability. On December 4, 2015, Moog Inc. (NYSE: MOG.A and MOG.B) announced that it acquired a 70% ownership of Linear Mold and Engineering with an option to acquire the remaining 30%. This recent sale of Linear Mold and Engineering in some respects represents the culmination of strategic acquisitions of what represented the initial service bureau providers of the early 2000's, starting with General Electric Aviation's purchase of Morris Technologies, and its sister company, Rapid Quality Manufacturing, in 2012. As a result, OEMs like Moog, GEA and Honeywell Aerospace seek to build internal capacity while ensuring sourcing for their first generation AM metal parts. While these strategic acquisitions represent an attempt by large OEMs to secure much needed production expertise for first generation AM proprietary components, their second and future generation components will require a capable service provider market base to supply these much needed components. Sigma believes that this service provider market segment represents an opportunity for Sigma to capture significant portions of the growing demand for metal production parts. Accordingly, Sigma acquired its first EOS M290 machine in 2014. Using the highly reliable 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 technology. 3. Biomedical Implant Technology. The Company has developed and demonstrated at a working prototype level the ability to modify the surface of a metal substrate, in this case, a commercially available dental implant made from commercially pure (CP) titanium. The Company does not currently have the resources to continue its commercialization efforts of such technology without the assistance of a partner or licensee. 4. Advanced Munitions Technology . The Company has developed and demonstrated at a working prototype level several classes of energetic materials which have structural strength until impact, and then release energy into the target without generating dangerous shrapnel which could fly out of the explosion zone. The Company believes that this selective munitions technology, if commercialized, will enable our forces to engage the enemy without harming civilians and will enable drones to have new strike capabilities. The Company does not currently have the resources to continue its commercialization efforts of such technology without the assistance of a partner or licensee. The Company has licensed the technology to Allotrope Sciences Corporation ("Allotrope") under an exclusive license agreement with Allotrope entered into in April 2013, pursuant to which we granted Allotrope rights to market and sell Sigma's ARMS™ and BAM™ technologies to U.S. and Foreign Government customers. Allotrope has not made any sales as of the date of this Annual Report. A detailed description of our technologies and business follows: Next-Generation Quality Assurance Solutions 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 files without any tooling or other processing. The sale of AM products and services is expected to exceed $7.3 billion worldwide by 2016. The AM industry is expected to more than quadruple to about $12.8 billion by 2018. By 2020, the AM industry is forecasted to exceed $21 billion, all according to Wohlers 2015 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 firms such as Honeywell Aerospace, GEA and Boeing Aircraft Company 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." The Company believes that OEM companies such as GE, Honeywell as well as first tier suppliers like Woodward, Inc. (NASDAQ: WWD) and Parker Hannifin (NYSE: PH) 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. The Company believes that our PrintRite3D® technology would directly address this "important barrier" for metal parts and allow such AM applications to move forward. In response to this need, the Company has experienced an increase in its installed base of PrintRite3D® systems and we are beginning to provide 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 ("3DMT"), Trumpf Laser and the Edison Welding Institute ("EWI"). 3 As further evidence of the demand for new quality assurance and control methods for safety-critical additive manufacturing metal parts and particularly for aging fleets with severe parts supply issues, the Office of Naval Research held an Industry Day on 28 July 2015 which was attended by large and small defense contractors interested in providing metal AM parts to Navy Depots and Fleet Readiness Centers. The Navy explained its needs and its forthcoming request for proposals for its program titled, "Quality Metal Additive Manufacturing (Quality Made) Enabling Capability". The proposed program goals are designed to address, in part, the Navy's need for assuring part quality in- situ (real-time), controlling the AM process parameters to control microstructure, volume and geometry, and collecting build data to support rapid qualification and certification for metal AM parts. The Company believes this is precisely the technology that can be provided by our PrintRite3D® technology. There is currently a very limited supplier base providing such value-added, in-process quality assurance for performance and safety-critical metal parts including the OEM AM machine producers. We believe that none are currently capable of addressing the issue of real-time quality assurance and process control ultimately leading to rapid qualification and part certification. Our PrintRite3D® technology is currently a market leader in this area. The Company has ongoing contracts that include a Period 2 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 provides an early opportunity to further demonstrate how our IPQA®-enabled PrintRite3D® technology 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, Sigma was a participant on a GEA led team of companies and universities, which were 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. The program start was delayed, however it is currently underway and its period of performance is expected to run into early 2017. In support of this effort, Sigma was awarded related contracts from the subcontractor Aerojet Rocketdyne to install one of our PrintRite3D® systems 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 AM system. 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. Lastly, 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 AM system to build canonical shapes and mechanical test specimens for evaluation by Honeywell Aerospace. Technology and Competitive Advantage The evolution of AM from prototyping to manufacturing in production runs is widely known to be 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 Sigma’s 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. Sigma’s 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. 1. PrintRite3D® SENSORPAK™ – the auxiliary sensor and hardware kit that sits on every AM machine to collect the data to drive the software. 2. PrintRite3D® INSPECT™ – software which verifies quality layer by layer. 3. PrintRite3D® CONTOUR™ – software which assures the as-built geometry. The following software modules are currently in development: 4. PrintRite3D® THERMAL™ – software which predicts the residual stress and distortion in the part. 5. PrintRite3D® ANALYTICS™ – software that harvests, aggregates, and analyzes big data from in-process and post process data. 4 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. Sigma has been aggressive in patent protecting its in depth data analysis and quality algorithms to link its 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 manufacturers as well as control system manufacturers such as Materialise BV or Siemens may use the Sigma data stream to direct machine performance adjustments. Sigma believes that it has developed an essential 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 very high quality yields, by measuring the product of the manufacturing equipment rather than just the equipment settings, it also is the most 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. Reciprocally, Sigma believes that Additive Manufacturers using equipment without PrintRite3D® will be at a substantial competitive disadvantage in production-run manufacturing for both cost and quality assurance. The Company believes that the broad domain coverage of its PrintRite3D® patents and metallurgical know-how make the licensing of its 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, by precisely adjusting laser power to sustain manufacturing to design and specification. Sigma appears well positioned to provide the metal AM market a product offering for real-time quality assurance and process control based on our core competency in real-time quality monitoring and process control called PrintRite3D®. Our IPQA®-enabled PrintRite3D® technology appears ideally 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® will be a vital enabler for metal AM to realize its full potential. Sigma has 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. We believe that Sigma's unique process know how, trade secrets and methodology for implementation of IPQA® for production AM, and U.S. patent awards and patents pending for quality monitoring and process control for processes specifically including AM, along with its PrintRite3D® technology has uniquely positioned Sigma to be a leader in the market space for in-process quality assurance technologies and solutions for metal AM. Our proven, sophisticated and proprietary analysis software has been demonstrated and tested at many manufacturing sites around the world. These demonstrations have served to validate the underlying technology of PrintRite3D® INSPECT™ and SENSORPAK™ software and hardware modules, respectively. In addition, Sigma has strategic relationships with experienced aerospace companies in North America that have assisted in the validation of the underlying technology for our PrintRite3D® software module known as CONTOUR™. Also, we continue to work with General Electric under our Joint Technology Development Agreement ("JTDA"), dated April 10, 2013, with General Electric to demonstrate and implement our in-process inspection technologies for additive manufactured jet engine components. Lastly, we are continuing to work with Honeywell Aerospace on the separate development of our PrintRite3D® CONTOUR™ software module 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. In addition, we have expanded our market presence and associated installed base of PrintRite3D® systems through our Early Adopter Program (EAP) and our OEM Partner Program to include European companies in France, Germany and The Netherlands. These European partners' installations are key to Sigma's long term strategy to broaden its installed base through our EAP program as well as gain market presence though embedded OEM offerings of our PrintRite3D® technology. At this stage in our PrintRite3D® product commercialization efforts, our PrintRite3D® sales reflect the strategic nature of our selective alliance partnerships. 5 PrintRite3D® is uniquely positioned to grow into this market because its technology is agonistic and deployable with all currently known metal AM manufacturing units. Sigma personnel’s metallurgical expertise combines with the Company's professionally crafted intellectual property protections to make the Company an attractive and largely necessary partner to each of the major AM OEM equipment manufacturers as well as each of the production oriented AM contract manufacturing enterprises. Business Model Sigma’s current commercialization strategy for PrintRite3D® products is: (i) enter into early adopter license agreements with high potential future AM equipment manufacturers and complex part AM manufacturing service bureaus; (ii) enter into OEM license agreements for PrintRite3D® with major AM equipment manufacturers; (iii) provide engineering consulting services on manufacturing and materials technology to third parties that have needs in developing next-generation technologies for materials and manufacturing projects; and (iv) build and run a contract manufacturing division for metal AM commencing with Sigma’s EOS M290. In 2016 and for 3-5 years going forward, Sigma’s PrintRite3D® technology sales prospects and trends will be asymmetric to the ups and downs of the AM industry’s sales of manufacturing equipment because the existing manufacturing base of AM machines is so much larger than PrintRite3D®’s 2015 installed base and because PrintRite3D® will be marketed to both the current installed base of AM manufacturing equipment and to OEM manufactures of new AM equipment coming on-line. Thus, from 2016 through 2019, Sigma expects its sales curve to be steeper and become less volatile than the general industry growth of new AM equipment sales. The Company believes that since PrintRite3D® systems are designed to run on different machine platforms this allows us to maximize our product offering to the entire AM metal market. The target markets include OEMs both on the AM software side such as Materialise BV as well as machine producers, including, but not limited to, EOS, Concept Laser, SLM, Renishaw PLC (LON: RSW), Additive Industries, and Trumpf Laser. 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 we have recently announced 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 therefore envision extending our competitive advantage in the future by further developing and offering a PrintRite3D® suite of Apps which would be specifically developed to improve part designs and significantly reduce traditional trial and error design approaches for features such as distortion control. By combining the AM competency of leading OEM manufacturers with Sigma’s complete systems package of real-time nondestructive inspection technology, a unique product offering will eventually be available to end-users. After installing Sigma’s complete PrintRite3D® systems package, which includes our ANALYTICS™ database systems package, OEM’s and principal end users will finally have the ability to address one the most important barriers to qualification of AM parts, i.e., linking of in- process feature data with post-process microstructural and mechanical property data. Finally, utilizing our EAP program as a starting point, ‘user’ advisory groups are being formed to facilitate exchange of information, needs, and new developments providing for shared user experiences. Recently, the European Industrie 4.0 group combined forces with the North American Industrial Internet Consortium to take the first steps towards adopting a common vision for the Internet of Things ("IoT") in the industrial applications space. Sigma is closely monitoring these developments as we formulate our own IoT strategy to ensure that our products and services will be fully compatible with the emerging industry trends. The Company currently has a healthy pipeline of opportunities with US Fortune 500 companies including GE and Honeywell and outside the United States, with large European manufacturers of AM equipment, and in China, with a cadre of AM adopters. The launch of the Company’s PrintRite3D® Operating Division in August 2015 led to an immediate buildup up in RFQ backlog and pending orders. To summarize, Sigma has formed an operating division focused on real-time, advanced quality assurance solutions for additive manufacturing thereby increasing the value of the AM part. Contract Manufacturing / Service Bureau for Metal Additive Manufacturing The Market According to the Wohlers 2015 Report, in 2014 the Additive Manufacturing industry’s primary and secondary worldwide revenues were $5.75 billion up 31% from 2013 - the largest year-to–year percentage revenue increase in 14 years. Wohlers forecasts that AM’s primary revenues alone will top $7.4 billion in 2016. Sigma’s initial target market within this burgeoning marketplace is the production of metal parts. Currently estimated to be ~15% of the total revenues in the AM markets, the high dollar value of 3D manufactured metal parts is expected to rapidly grow AM metal manufacturing’s share of total AM revenues as the technology is deployed increasingly away from prototyping and into dedicated production. Extrapolating from Wohlers, this would be an AM metal products market of $4-6 billion in 2020. 6 Based on current market demand and growth trends, the contract manufacturing division appears to have the potential to be a significant revenue and profit center even as it also serves Sigma as an on-going research arm for exploring and characterizing new metals for use in all AM metal manufacturing equipment and for staying current on state of the moment 3D manufacturing requirements and thus possible enhancements to PrintRite3D®. A well regarded U.S. Brokerage Firm reported in November 2015 that based upon that month’s FormNext Trade show in Germany that (AM) “Metal Demand is extremely strong. SLM Solutions has seen YTD 2015 orders +78% while the value of orders are +115% (so the mix is shifting toward its larger, more expensive units. It believes 2016 can grow nicely on top of this growth. A large private metals OEM expects 2016 unit growth of 30-60%. The booths of metals OEMs were packed. The consensus is that significant runway remains for metal printers.” The firm went on to assert, “Metals are robust in 2015, and expected to be again in 2016 as the march to final parts continues.” As demand continues to increase for 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, 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 the aforementioned merger and acquisition activities since 2012, and what remains is small, fragmented and less capable than the first generation of service bureau providers. Such service bureau also does not currently have the capacity to meet the expected future demand for AM parts in the next 18 to 24 months. 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 continuing to pursue business opportunities related to AM utilizing the Company's EOS M290 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, i.e., 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 system is outfitted with our latest PrintRite3D®-enabled technology allowing us to provide customers with the necessary "objective evidence of compliance", or QA 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. Business Model We believe that given the limited service bureau provider capacity due to the merger and acquisition activities in the industry of the past several years, there is now a very real need for AM service providers to allow us to establish an immediate and strong presence and expand into a leading provider of AM produced metal parts. We envision a business model comprising revenues from contract, metal AM manufacturing sales for prototyping services as well as Small Lot Intelligent Manufacturing™ (SLIM®) sales for low-rate initial production ("LRIP") products requiring our PrintRite3D® technology. The target markets would be end users requiring high-end metal parts such as in the aerospace, oil & gas, bio-medical and automotive markets. To summarize, Sigma has formed an operating division focused on contract additive manufacturing and its AM facility keeps Sigma on the cutting edge of 3D metal additive manufacturing as the Company works with the market to develop state of the moment solutions and to characterize new materials and approaches. Biomedical Prosthetics, Implants and Munitions Technologies: Next Generation The Company also has dental and munitions technologies. If we identify suitable licensees or commercialization partners with respect to these technologies, we expect to limit our activities in these areas to marketing assistance. In April 2013, Sigma entered into an exclusive license agreement with Allotrope. Under the agreement, Allotrope is obligated to pay specified license fees and low single digit royalties on sales relating to the licensed patents. The initial term of the agreement is five years, unless sooner terminated as provided in the agreement, which may be renewed by Allotrope for up to three additional periods of one year each after the expiration of the initial term. Additionally, Allotrope may consider sales to system integrators requiring enhancements to current weapons systems where it makes business sense. We have not yet identified and may not be successful in identifying a credible commercialization partner for our biomedical prosthetics and implant technology. 7 Recent Developments (in reverse chronological order) On March 7, 2016, we announced that we received a contract from Aerojet Rocketdyne, a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE: AJRD), for a non- exclusive license of the Company's PrintRite3D® software applications. Our technology will be utilized on Aerojet Rocketdyne’s contract with the U.S. Air Force to define more efficient processes for qualifying AM components, and be evaluated for liquid-fueled rocket engine applications. The broader Air Force initiative is part of a plan to transition away from the Russian-made RD-180 engines currently used on the Atlas V launch vehicle. Separately, we received an order from Aerojet Rocketdyne under the previously-announced “America Makes” additive manufacturing research project with GE Aviation. The program, funded by the National Additive Manufacturing Innovation Institute (NAMII), uses our proprietary In-Process Quality Assurance™ (IPQA®) software for advanced AM monitoring. This is the second PrintRite3D® system being deployed under America Makes, the first being with GE Aviation. On January 27, 2016, we announced that we entered into a technology development agreement with 3DSIM, LLC to pursue commercial metal AM software opportunities for rapid qualification and part certification. 3DSIM, based in Park City, Utah, is a provider of simulation software for metal AM processes. On November 30, 2015, we announced that a company in Germany has entered into an evaluation period for our proprietary PrintRite3D® products. As part of the agreement this customer, which wishes to remain anonymous at the present time, purchased a non-exclusive license to test the Company's PrintRite3D® applications in certain of its laser-based powder bed metal machines – some of which were on display at the recent Formnext show in Frankfurt, Germany. On September 30, 2015, we announced the launch of our long-awaited CONTOUR™ software – part of the Company’s PrintRite3D® family of quality assurance and process control products. Sigma has completed all in-house development and testing such that CONTOUR™ is now available for beta installations, including for customers within the Company’s Early Adopter Program (EAP). The first fielded application of CONTOUR™ is with Honeywell Aerospace at its AM development facility in Phoenix. On September 17, 2015, we announced the launch of an “OEM Partner Program” to expedite the trial and incorporation of the Company’s PrintRite3D® quality assurance software into AM machines worldwide. On September 11, 2015, we announced that we had entered into an evaluation period for the Company’s proprietary PrintRite3D® products with Additive Industries of The Netherlands. As part of the agreement, Additive Industries has purchased a non-exclusive license to use one of our PrintRite3D® systems – including licensing of its INSPECT™, CONTOUR™ and ANALYTICS™ software – to be integrated into a MetalFAB1 prototype machine for evaluation purposes. As previously announced, the two companies signed a Technology Cooperation Agreement in December, 2014 to evaluate our technology for Additive Industries’ system development. On September 1, 2015 – we announced the launch of our EAP to accelerate adoption of the Company’s groundbreaking PrintRite3D® quality assurance software for 3D printing. We have already won a contract under this initiative – our EAP – with Spartacus3D, a unit of France’s Farinia Group. On May 4, 2015, we announced that Honeywell has entered into a contract with the Company to acquire our PrintRite3D® system. As part of the award, we delivered and installed our PrintRite3D® INSPECT™ software – including one license and a year of maintenance – for Honeywell to test within its AM development facility in Phoenix; the purchase order also included our first contract for our groundbreaking DEFORM™ software. On April 1, 2015, we announced that we became a Silver member of the America Makes consortium to further advance our presence in the 3D printing space, and continue to collaborate with leading companies and organizations in the field. 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. 8  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., IMPACT Engineering, Inc, Computer Weld Technology, Inc. and Vibrant Corporation that specialize in designing and manufacturing automated welding equipment and quality control monitoring devices used in industrial applications, as well as Aerojet Ordnance, General Dynamics Ordnance and Tactical Systems, Alliant Techsystems Inc. and Energetic Materials and Processes, Inc., all of which are businesses focused on developing materials technology solutions in the advanced munitions market; and Straumann AG, BioMet 3I, Keystone Dental, HiOssen Dental, and companies that specialize in developing dental implants that heal rapidly. 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. The Company’s research and development expenses relate to its 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, 2015 and 2014, the Company recognized $330,554 and $219,132, of research and development costs, respectively. Intellectual Property We regard our patents, trademarks, domain names, trade secrets, process knowledge, and other intellectual property as critical to our success. We rely on patent, trademark and other intellectual property law, and confidentiality agreements with employees, partners, and others to protect our intellectual assets. During 2015, Sigma retained the International intellectual property law firm of Kilpatrick Townsend & Stockton LLP to assist the Company with maintaining and extending our ability to have sufficient freedom to operate as well as appropriate patents in place. The below chart summarizes our issued patents. We are currently prosecuting eight foreign and U.S. applications related to our IPQA® technology and rapid qualification of additive manufacturing for metal parts. One of these eight patent applications published in November 2015. There is no guarantee that the patents for which we have applied will offer adequate protection under applicable law. Title Controlled Weld Pool Volume Control of Welding Processes Structurally Sound Reactive Materials Composite Projectile Type US Utility US Utility US Utility Patent No. 8,354,608 8,372,224 8,359,979 Government Regulation Our business activities are 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. 9 Employees As of March 16, 2016, the Company had eleven full-time employees and no part-time employees. 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 IPQA® for AM, as well as contract manufacturing in the AM service provider sector.

ITEM 1A. RISK FACTORS. 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. Risks Related to Our Business and Industry We have a limited operating history, which makes it difficult to evaluate an investment in the Company. Since we commenced business operations in 2010 and are continuing to develop our technologies and implement our operating tactics, it can be expected that we will continue to incur significant operating expenses and will experience significant losses in the foreseeable future. There is no assurance that any revenues we generate will be sufficient for us to become profitable or thereafter maintain profitability. As a result, the Company cannot predict when, if ever, it might achieve profitability and cannot be certain that it will be able to sustain profitability, if achieved. Our relatively short operating history may make it difficult for you to evaluate our business prospects in connection with an investment in our securities. We face many of the risks normally associated with a new business. We face all 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. We may not be able to obtain sufficient financing, and may not be able to further develop our technologies. We believe that our existing cash and cash equivalents, along with revenue from our existing contracts, should be sufficient to fund our operations for at least twelve months. This projection is based on our current planned operations and revenue expectations and is subject to changes in our plans and uncertainties inherent in our business, and we may need to seek to replenish our existing cash and cash equivalents sooner than we project. In the future, we will seek to obtain further financing from third parties in order to maintain our operations and to grow our business. We cannot assure that additional funding to maintain our operations will be available to us in the future on acceptable terms, or at all. If we fail to obtain additional funding when needed, we would be forced to scale back, or terminate, our operations, or to seek to merge with or to be acquired by another company. 10 Any additional financing we may undertake could result in dilution to existing stockholders. Any additional financings we undertake in the future may be obtained through one or more transactions involving the issuance of our capital stock, which will dilute (either economically or in percentage terms) the ownership interests of our stockholders. Our business may be adversely affected by the 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 the Company’s 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. If we fail to hire a chief financial officer, we may be unable to implement and monitor financial controls sufficient to ensure maximum profitability and compliance with applicable regulatory requirements. We currently have no Chief Financial Officer (“CFO”) and we may not be in the position to hire a CFO in the near future due to the expense of employing a CFO and our limited capital resources. Monica Yaple is a consultant working as our Treasurer, and she also presently acts as our principal financial and accounting officer. Unless we obtain the services of a qualified CFO, we may be unable to implement and monitor financial controls sufficient to ensure maximum profitability and compliance with applicable regulatory requirements. We are not subject to certain reporting requirements under the federal securities laws – accordingly, our stockholders do not have the benefit of certain disclosures prior to voting on material transactions or the benefit of reviewing information regarding our officers’ and directors’ stock ownership and their transactions involving our securities. We are currently subject to SEC reporting requirements under Section 15(d) of the Exchange Act of 1934, as amended (the “Exchange Act”). Because we have not filed a registration statement under Section 12 of the Exchange Act, we are not subject to the SEC’s proxy rules and related information requirements of the Exchange Act. Further, our officers, directors and stockholders owning 10% or more of our outstanding capital stock are not required to file reports with the SEC concerning their stock ownership and stock trading activity under Section 16 of the Exchange Act, which provides for timely disclosure of insider transactions. Accordingly, our shareholders do not have the benefit of (i) certain disclosures required under the SEC’s proxy rules in connection with their approval of certain corporate actions (e.g., significant acquisitions and election of directors); and (ii) disclosures about our officers’ and directors’ ownership of and their transactions involving the Company’s securities. 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 such 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 Request for Proposals or “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. 11 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 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 will likely 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. 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. 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 have 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 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 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 a little over 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. 12 Failure to obtain adequate insurance coverage could put the Company at risk for uninsured losses. We currently have liability insurance. Some or all of the Company’s customers may require insurance as a requirement to conduct business with the Company. 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 the Company can afford or at all. Claims or losses in excess of any insurance coverage we may obtain, or the lack of insurance coverage, could put the Company 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, the loss of which could harm our business. The Company depends on Mark J. Cola, its President and Chief Executive Officer, as well as key scientific and other personnel. The loss of any of these individuals could harm the Company’s business and significantly delay or prevent the achievement of business objectives. In addition, our delivery of services will be labor-intensive: when the Company is 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. Because we have limited capital resources, 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. 13 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 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 shareholders 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 we anticipated. The Company must keep up with new and rapidly evolving technologies. Many of the Company’s 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 the Company’s control. Our success depends upon our ability to protect our intellectual property rights. Our success in part depends on the Company’s ability to maintain the proprietary nature of our technology and other trade secrets. To do so, we will be required to prosecute 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 eight 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. 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. Prosecuting infringement claims can be expensive and time-consuming. In addition, in an infringement proceeding, a court may decide that a patent owned by us is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that the Company’s patents do not cover its technology. An adverse determination of any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put the Company’s patent applications at the risk of not issuing. Any significant impairment of our intellectual property rights could harm our business or our ability to compete. The unauthorized use of our intellectual property could make it more expensive to do business and harm our operating results. 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 the Company does 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 the Company 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. Our services are subject to government regulation, changes in which may have an adverse effect on the Company. Our business activities subject us to a variety of federal, state and local laws and regulations. For example, we would be required to comply with applicable provisions of the International Traffic in Arms Regulations, as well as other export controls and laws governing the manufacture and distribution of munitions technology. Despite the fact that Sigma has 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. 14 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. Our Bylaws do not contain anti-takeover provisions, which could result in a change of our management and directors if there is a takeover of us. We do not currently have a shareholder rights plan or any anti-takeover provisions in our Bylaws. Without any anti-takeover provisions, there is no deterrent for a takeover of our company, which may result in a change in our management and directors. Our operating costs could be 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 our company 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 can be 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. Risks Related to Our Common Stock We do not foresee paying cash dividends in the foreseeable future and, as a result, our investors’ sole source of gain, if any, will depend on capital appreciation, if any. We do not plan to declare or pay any cash dividends on our shares of common stock in the foreseeable future. As a result, investors should not rely on an investment in our securities if they require the investment to produce dividend income. Capital appreciation, if any, of our shares may be investors’ sole source of gain for the foreseeable future. Our securities are considered highly speculative. Our securities must be considered highly speculative, generally because of our limited operating history. We have neither generated any material revenues nor have we realized a profit from our operations to date and there is no assurance that we will operate on a profitable basis. Since we have not generated any material revenues, we expect that we will need to raise additional monies through the sale of our equity securities or debt in order to continue our business operations. 15 The market price and trading volume of our common stock may be volatile. The market price of our common stock has exhibited substantial volatility. Between January 1, 2015 and March 16, 2016, the sale price of our common stock as reported on the OTCQB ranged from a low of $0.0401 to a high of $0.125. The market price of our common stock could continue to fluctuate significantly for many reasons, including the following factors: · · · · · · · announcements of regulatory developments or technological innovations by us or our competitors; announcements of business or strategic transactions; changes in our relationship with our strategic partners; our quarterly operating results; developments in patent or other technology ownership rights; additional funds may not be available on terms that are favorable to us and, in the case of equity financings, may result in dilution to our stockholders; and general changes in the economy, the financial markets or the industry in which we operate. In addition, factors beyond our control may also have an impact on the price of our common stock. For example, to the extent that other large companies within our industry experience declines in their stock price, our stock price may decline as well. In addition, when the market price of a company’s common stock drops significantly, security holders often institute securities class action lawsuits against the company. A lawsuit against us could cause us to incur substantial costs and could divert the time and attention of our management and other resources. Offers or availability for sale of a substantial number of shares of our common stock may cause the price of our common stock to decline. If our stockholders sell substantial amounts of our common stock in the public market upon the expiration of any statutory holding period, under Rule 144 promulgated under the Securities Act of 1933, as amended, or issued upon the exercise of outstanding options or warrants, or otherwise, it could create a circumstance commonly referred to as an “overhang” and in anticipation of which the market price of our common stock could fall. The existence of an overhang, whether or not sales have occurred or are occurring, also could make more difficult our ability to raise additional financing through the sale of equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate. We may issue preferred stock in the future, and the terms of the preferred stock may reduce the value of our common stock. We are authorized to issue up to 10,000,000 shares of preferred stock in one or more series. Our board of directors may determine the terms of future preferred stock offerings without further action by our stockholders. If we issue preferred stock, it could affect your rights or reduce the market value of our outstanding common stock. In particular, specific rights granted to future holders of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights, sinking fund provisions, and restrictions on our ability to merge with or sell our assets to a third party. Our common stock may be considered a “penny stock,” and thereby be subject to additional sale and trading regulations that may make it more difficult to sell. Our common stock may be a “penny stock” if it meets one or more of the following conditions (i) the stock trades at a price less than $5.00 per share; (ii) it is not traded on a “recognized” national exchange; (iii) it is not quoted on the Nasdaq Capital Market, or even if so, has a price less than $5.00 per share; or (iv) is issued by a company that has been in business less than three years with net tangible assets less than $5 million. The principal result or effect of being designated a “penny stock” is that securities broker-dealers participating in sales of our common stock will be subject to the “penny stock” regulations set forth in Rules 15-2 through 15g-9 promulgated under the Exchange Act. For example, Rule 15g-2 requires broker-dealers dealing in penny stocks to provide potential investors with a document disclosing the risks of penny stocks and to obtain a manually signed and dated written receipt of the document at least two business days before effecting any transaction in a penny stock for the investor’s account. Moreover, Rule 15g-9 requires broker-dealers in penny stocks to approve the account of any investor for transactions in such stocks before selling any penny stock to that investor. This procedure requires the broker-dealer to (i) obtain from the investor information concerning his or her financial situation, investment experience and investment objectives; (ii) reasonably determine, based on that information, that transactions in penny stocks are suitable for the investor and that the investor has sufficient knowledge and experience as to be reasonably capable of evaluating the risks of penny stock transactions; (iii) provide the investor with a written statement setting forth the basis on which the broker-dealer made the determination in (ii) above; and (iv) receive a signed and dated copy of such statement from the investor, confirming that it accurately reflects the investor’s financial situation, investment experience and investment objectives. Compliance with these requirements may make it more difficult and time consuming for holders of our common stock to resell their shares to third parties or to otherwise dispose of them in the market or otherwise. 16 If securities or industry analysts do not publish research or reports or publish unfavorable research about our business, the price and trading volume of our common stock could decline. The future trading market for our common stock will be influenced in part by any research and reports that securities or industry analysts publish about us or our business. We do not currently have and may never obtain research coverage by securities and industry analysts. If no securities or industry analysts commence coverage of us the trading price for our common stock and other securities would be negatively affected. In the event we obtain securities or industry analyst coverage, if one or more of the analysts who covers us downgrades our securities, the price of our securities would likely decline. If one or more of these analysts ceases to cover us or fails to publish regular reports on us, interest in the purchase of our securities could decrease, which could cause the price of our common stock and other securities and their trading volume to decline. If we are deemed to be an issuer of “penny stock”, the protection provided by the federal securities laws relating to forward-looking statements will not apply to us. Although federal securities laws provide a safe harbor for forward-looking statements made by a public company that files reports under the federal securities laws, this safe harbor is not available to issuers of penny stocks. As a result, if we are a penny stock, we will not have the benefit of this safe harbor protection in the event of any legal action based upon a claim that the material provided by us contained a material misstatement of fact or was misleading in any material respect because of our failure to include any statements necessary to make the statements not misleading. Such an action could hurt our financial condition. Financial Industry Regulatory Authority (FINRA) sales practice requirements may also limit a stockholder’s ability to buy and sell our common stock. FINRA has adopted rules that require that in recommending an investment to a customer, a broker-dealer must have reasonable grounds for believing that the investment is suitable for that customer. Prior to recommending speculative low priced securities to their non-institutional customers, broker-dealers must make reasonable efforts to obtain information about the customer’s financial status, tax status, investment objectives and other information. Under interpretations of these rules, FINRA believes that there is a high probability that speculative low priced securities will not be suitable for at least some customers. FINRA requirements make it more difficult for broker- dealers to recommend that their customers buy our common stock, which may limit your ability to buy and sell our stock and have an adverse effect on the market for our shares. We may incur significant costs to ensure compliance with U.S. corporate governance and accounting requirements. We may incur significant costs associated with our public company reporting requirements, costs associated with applicable corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, and other rules implemented by the SEC. 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 controls over financial reporting, the price of our common stock may be adversely affected. As a public reporting company, we are required to establish and maintain appropriate internal controls over financial reporting. Failure to establish those controls, or any failure of those controls once established, could adversely impact our public disclosures regarding our business, financial condition or results of operations. Any failure of these controls could also prevent us from maintaining accurate accounting records and discovering accounting errors and financial frauds. 17 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 controls over financial reporting may identify weaknesses and conditions that need to be addressed in our internal controls 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 controls over financial reporting may have an adverse impact on the price of our common stock. Obtaining additional capital through the sale of common stock will result in dilution of equity interests. We plan to raise additional funds in the future by issuing additional shares of common stock or other securities, which may include securities such as convertible debentures, warrants or preferred stock that are convertible into common stock. Any such sale of common stock or other securities will lead to further dilution of the equity ownership of existing holders of our common stock. Additionally, the existing options, warrants and conversion rights may hinder future equity offerings, and the exercise of those options, warrants and conversion rights may have an adverse effect on the value of our stock. If any such options, warrants or conversion rights are exercised at a price below the then current market price of our shares, then the market price of our stock could decrease upon the sale of such additional securities. Further, if any such options, warrants or conversion rights are exercised at a price below the price at which any particular shareholder purchased shares, then that particular shareholder will experience dilution in his or her investment. ITEM 1B. UNRESOLVED STAFF COMMENTS. Not applicable. ITEM 2. PROPERTIES. The Company leases at 3900 Paseo del Sol, Santa Fe, New Mexico 87507, approximately (i) 3,100 square feet of office space at Units C-14, C-15, C-16, C-17 and C- 20, for a total monthly rent expense of approximately $2,425 under the lease, which expires on July 31, 2016, (ii) 708 square feet of production space at Unit E-42, for a total monthly rent expense of approximately $775 under the lease, which expires on September 30, 2016, (iii) 708 square feet of production space at Unit E-38, for a total monthly rent expense of approximately $775 under the lease, which expires on December 31, 2016, and (iv) 512 square feet of warehouse / production space at Unit E-40, for a total monthly rent expense of approximately $650 under the lease, which expires on September 30, 2016. We believe that our facilities are suitable for our current needs. ITEM 3. LEGAL PROCEEDINGS. We are not currently a party to any legal proceedings. However, we may occasionally become subject to legal proceedings and 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. ITEM 4. MINE SAFETY DISCLOSURES. Not Applicable. PART II ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES. Market Information Our common stock is quoted for trading on the OTCQB under the symbol “SGLB.” The following table sets forth the range of closing prices for our common stock for the quarters indicated. Such quotations reflect inter-dealer prices, without retail mark-up, mark-down or commission and may not necessarily represent actual transactions. Fiscal Year Ended December 31, 2015 First Quarter Second Quarter Third Quarter Fourth Quarter High Bid Low Bid $ $ $ $ 0.095 $ 0.125 $ 0.090 $ 0.096 $ 0.042 0.070 0.050 0.050 18 Fiscal Year Ended December 31, 2014 First Quarter Second Quarter Third Quarter Fourth Quarter Shareholders High Bid Low Bid $ $ $ $ 0.183 $ 0.175 $ 0.151 $ 0.115 $ 0.100 0.102 0.106 0.059 As of March 3, 2016, there were approximately 542 holders of record of our common stock based on information provided by our transfer agent. 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 Not applicable. Repurchase of Shares We did not repurchase any of our shares during the fourth quarter of the fiscal year covered by this report. ITEM 6. SELECTED FINANCIAL DATA. Not applicable to a “smaller reporting company” as defined in Item 10(f)(1) of SEC Regulation S-K. 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 affect on our financial statements. Results of Operations Year Ended December 31, 2015 Compared to the Year Ended December 31, 2014. 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, 2015 (“fiscal 2015”), we generated an aggregate of $1,234,810 in revenues, as compared to an aggregate of $548,723 in revenues that were generated by us during the fiscal year ended December 31, 2014 (“fiscal 2014”). The increase in revenue was primarily due to our ongoing work under additional contracts as compared to the prior year. We generated revenues and financed our operations in fiscal 2015 and fiscal 2014 primarily from engineering consulting services we provided to third parties during these periods and through private sales of our common stock. 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. 19 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. In fiscal 2014, B6 Sigma along with Sumner Associates generated an aggregate of $548,723 in revenue from consulting and other contracts. Sumner Associates generated $11,312 of such revenue. Our other general and administrative expenses for fiscal 2015 were $1,282,952, as compared to $1,020,262 in fiscal 2014. Our payroll expenses for fiscal 2015 were $585,706, as compared to $404,054 for fiscal 2014. Our expenses relating to non-cash compensation for fiscal 2015 were $518,438, as compared to $582,550 for fiscal 2014. Our research and development expenses for fiscal 2015 were $330,554, as compared to $219,132 for fiscal 2014. In fiscal 2014, we also incurred a non-recurring warrant expense of $1,283,333. 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, and research and development expenses in fiscal 2015 as compared to fiscal 2014 is principally the result of increased research and development costs, investor relations expenditures and consultant services provided to us due to an increase in our overall business activities, including 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 2015 as compared to fiscal 2014 is principally the result of our hiring of ten employees since mid 2014. The Company incurred $518,438 of non-cash compensation expenses during 2015, $334,500 of which was the result of the vesting of a total of 3,000,000 shares of Company common stock issued to three of our employees and a director pursuant to the Company's 2013 Equity Incentive Plan. The other $183,938 was non-cash compensation paid to our consultants, employees and directors during 2015. 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 2015 decreased overall and totaled $1,696,282, as compared to $3,116,080 for fiscal 2014. The most significant factor in the decrease in our net loss was the result of a non-recurring 2014 expense of $1,283,333 relating to the extension of the term of a warrant, along with our increased revenue, which partially offset increases in our general and administrative, payroll and research and development expenses. Liquidity and Capital Resources As of December 31, 2015, we had $1,539,809 in cash and a working capital surplus of $1,785,728, as compared to $2,962,069 in cash and a working capital surplus of $2,811,606 as of December 31, 2014. 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 by providing contract AM services using our EOS M290 metal AM system. However, for the period from our inception through December 31, 2015, 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. During the remainder of 2016, 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 2016 and 2017. However, until commercialization of our full suite of PrintRite3D® technologies, we plan to continue funding our development activities and operating expenses by selling and 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. 20 Cash flows used in operating activities in 2015 increased to $1,259,685 from $888,560 in 2014 due primarily to reductions in accounts payable and increases in accounts receivable in 2015, and fewer non-cash expenses in 2015 partially offset by a reduction in net losses of $1,419,798. The Company anticipates fewer losses in 2016, due to increased revenues, offset by the increased cost of growth in salaries and related expenses in connection with our additional employees. Cash flows used in investing activities decreased substantially in 2015 from $839,610 to $162,575 primarily because we purchased our EOS M290 in 2014. Purchases in 2016 are not expected to increase dramatically over 2015. There were no cash flows used or provided by financing activities in 2015, whereas there was a private offering in 2014 that raised net proceeds of $3,697,791. As of March 16, 2016, we have seven active contracts with respect to which we expect to perform and generate up to approximately $690,000 in revenues in fiscal 2016, subject to the achievement by us of certain performance milestones, as well as our contracts not being terminated by our clients. We have no credit lines or facilities as of March 16, 2016, nor have we ever had a credit facility since our inception. We are continuing to evaluate potential future sources of capital, and we do not currently have commitments from any third parties to provide us with additional capital. Based on the funds we have as of March 16, 2016, and the proceeds we expect to receive under our PrintRite3D®-enabled engineering consulting agreements, from selling or licensing our PrintRite3D® systems and software, sales of contract AM manufacturing for metal AM parts, and from offerings of the Company's common stock, we believe that we will have sufficient funds to pay our administrative and other operating expenses through 2016. Until we are able to generate significant revenues and royalties from selling or 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 securities. Accordingly, we will 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 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. Not applicable to a “smaller reporting company.” ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. Financial Statements are referred to in Item 15, listed in the Index to Financial Statements and filed and included elsewhere herein as a part of this Annual Report on Form 10-K. ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. None. ITEM 9A. CONTROLS AND PROCEDURES. Evaluation of Disclosure Controls and Procedures Rule 15d-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. 21 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 15d-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, 2015. 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, 2015 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. ITEM 9B. OTHER INFORMATION Our consulting agreement with Monica Yaple, the Company’s Treasurer and Principal Accounting and Financial Officer, was amended on March 15, 2016, to extend the term of the agreement until December 31, 2016. Under the consulting agreement, we agreed to pay Ms. Yaple $75/hour, provided that our financial obligation to Ms. Yaple during the term of the agreement shall not exceed $25,075. The Company will hold its annual meeting of shareholders an April 28, 2016. ITEM 10. DIRECTORS, EXECUTIVE OFFICERS, AND CORPORATE GOVERNANCE.

Director Independence Our common stock is traded on the OTCQB under the symbol “SGLB”. The OTCQB electronic trading platform does not maintain any standards regarding the “independence” of the directors on our company’s board of directors, and we are not otherwise subject to the requirements of any national securities exchange or an inter-dealer quotation system with respect to the need to have a majority of our directors be independent. 28 In the absence of such requirements, we have elected to use the definition for “director independence” under the NASDAQ stock market’s listing standards, which defines an “independent director” as “a person other than an officer or employee of the Company or the Company’s subsidiaries or any other individual having a relationship, which in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.” The definition further provides that, among others, employment of a director by us (or any parent or subsidiary of ours) at any time during the past three years is considered a bar to independence regardless of the determination of our board of directors. All of our board members, except Mr. Cola, an employee-director, are deemed “independent” under the NASDAQ Stock Market’s listing standards. ITEM 14. PRINCIPAL ACCOUNTING FEES AND SERVICES.

Santa Fe, New Mexico We have audited the accompanying balance sheets of Sigma Labs, Inc. as of December 31, 2015 and 2014 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, 2015 and 2014 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.

NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2015 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 ultimatley leading to closed loop process control. The Company anticipates that its core technologies will allow its clientele to combine advanced manufacturing quality assurance and processs 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, 2015 and 2014 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. 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. The carrying amounts reported in the balance sheets for the cash and cash equivalents prepaid stock compensation, receivables and current liabilities each qualify as financial instruments and are a reasonable estimate of fair value because of the short period of time between the origination of such instruments and their expected realization and their current market rate of interest. Income Taxes – The Company accounts for income taxes in accordance with ASC Topic No. 740, “Accounting for Income Taxes.” F-6 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, 2015 and 2014 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, 2015, the Company recognized no interest and penalties. The Company had no accruals for interest and penalties at December 31, 2015 or 2014. 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. The allowance for doubtful accounts at December 31, 2015 and 2014 was $0 and $4,884 respectively. 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, 2015 or 2014. 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. 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. F-7 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.” 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 proposed 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 $20,129 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. F-8 Research and Development – Research and development costs are expensed as they are incurred. Research and development costs for the years ended December 31, 2015 and 2014 were $330,554 and $219,132, respectively. NOTE 2 – Stockholders’ Equity Common Stock The Company has authorized 750,000,000 shares of common stock, $0.001 par value. On May 23, 2013, the Company issued 2,000,000 shares of the Company’s common stock to a consultant as noncash compensation for services to be rendered valued at $45,400 or $0.0227 per share. Of these shares, 1,000,000 (valued at $22,700) vested immediately and 960,693 (valued at $21,808) vested during the year ended December 31, 2015. 39,307 shares (valued at $892) are vested but unearned by the consultant and are reflected as prepaid assets as of December 31, 2015. In January 2014, the Company issued 43,750,000 shares of stock to an investor for a total purchase price of $3,500,000. In connection with the purchase and sale of the shares, the Company agreed to issue to the investor a warrant to purchase up to 14,259,259 shares of the Company’s common stock, at an exercise price of $0.15 per share. The warrant had a term of nine months from the date of issuance (January 10, 2014) and had a fair value of approximately $1,212,037. In May 2014, the term of the warrant was extended by nine months to expire in July 2015 and had a fair market value in excess of the remaining fair market value of the original warrant of approximately $1,283,333. A warrant was also issued as part of the offering to a consultant to purchase up to 2,187,500 shares of common stock at $0.08 per share, valued at approximately $271,250. That warrant had a term of two years from the date of issuance (January 10, 2014). Offering costs paid from the proceeds of the offering were approximately $199,089. The fair value of the warrant of $1,212,037 was calculated using a Black-Scholes option pricing model with the following assumptions: expected life of nine months, expected volatility of 202%, a risk-free interest rate of 0.09%, and an expected dividend yield of 0%. The fair value of the warrant of $271,250 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 new warrant related to the extension of the warrant expiration of $1,283,333 (net) was calculated using a Black-Scholes option pricing model with the following assumptions: expected life of 14 months, expected volatility of 226%, a risk-free interest rate of 0.1%, and an expected dividend yield of 0%. F-9 In June 2014, the Company issued 6,250,000 shares of stock to an investor for a total purchase price of $500,000. In connection with the purchase and sale of the shares, the Company agreed to issue to the investor a warrant to purchase up to 2,037,037 shares of the Company’s common stock, at an exercise price of $0.15 per share. The warrant had a term of one year from the date of issuance (June 4, 2014) and had a fair value of approximately $132,407. A warrant was also issued as part of the offering to a consultant to purchase up to 312,500 shares of common stock at $0.08 per share, valued at approximately $36,250. That warrant has a term of two years from the date of issuance (June 4, 2014). Offering costs paid from the proceeds of the offering were approximately $25,035. The fair value of the warrant of $132,407 was calculated using a Black-Scholes option pricing model with the following assumptions: expected life of one year, expected volatility of 163%, a risk-free interest rate of 0.1%, and an expected dividend yield of 0%. The fair value of the warrant of $36,250 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%. During July 2014, the Company issued an aggregate of 6,000,000 shares of common stock to three employees valued at $0.129 per share or $774,000. Twenty-five percent of each employee’s shares vested immediately upon the grant date, 25% of such shares vested upon the first annual anniversary of each employee’s start date, and 25% of such shares will vest on each of the second and third annual anniversary of each employee's start date, provided that such employee remains in the Company’s continuous employ through such vesting dates. In November 2014, the Company issued 1,500,000 shares of stock to a director, subject to restrictions, pursuant to the Company's 2013 Equity Incentive Plan (the “2013 Plan”). The shares were valued at $0.094 or $141,000. All shares vested during the year ended December 31, 2015. In March 2015, the Company issued 1,000,000 shares of stock to a director. The Company also issued 500,000 shares of stock to an officer, and an aggregate of 2,103,774 shares of stock to two consultants, subject to vesting restrictions. The shares were issued pursuant to the 2013 Plan. The shares were valued at $0.053 or $191,000. 3,303,680 of the shares vested during the year ended December 31, 2015. The remaining 300,094 shares unvested at December 31, 2015 (valued at $15,905) are reflected as prepaid assets. In August 2015, in conjuction with the hiring of Ron Fisher, the Company's Vice President of Business Development, the Company issued to Mr. Fisher 250,000 shares of common stock, subject to performance-based vesting restrictions. In November 2015, the Company issued 62,500 shares of common stock to an employee valued at $0.065 per share, or $4,063, and issued 250,000 shares of common stock to an employee valued at $0.0615 per share, or $15,375. At December 30, 2015, there were 623,907,335 shares of common stock issued and 620,657,335 outstanding. At December 31, 2014, there were 619,741,061 shares issued and 612,741,061 outstanding, reflecting 3,250,000 and 7,000,000 shares respectively issued but unvested shares pursuant to the Company's 2011 Equity Incentive Plan (the “2011 Plan”) and the 2013 Plan. As of December 31, 2015, an aggregate of 150,000 shares and 17,083,726 shares of common stock were reserved for issuance under the 2011 Plan and the 2013 Plan, respectively, including 3,250,000 shares subject to vesting restrictions under the 2013 Plan. Deferred Compensation As described under the Common Stock heading above, during July 2014, the Company issued to three employees an aggregate of 6,000,000 shares of the Company’s common stock, subject to restrictions, pursuant to the 2013 Plan. Such shares were valued at the fair value of $774,000 or $0.129 per share. This compensation is being expensed over the vesting period. As of December 31, 2015, the balance of unvested compensation cost expected to be recognized is $387,000 (3,000,000 shares valued at $0.129) and is recorded as a reduction of stockholders’ equity. The unvested compensation is expected to be recognized over the weighted average period of approximately 2 years (through July 2017).

Preferred Stock The Company is authorized to issue 10,000,000 shares of preferred stock, $0.001 par value. No shares of preferred stock were issued and outstanding at December 31, 2015 and 2014. Stock Options During 2015, the Company granted a total of 5,187,500 options to three employees with vesting periods ranging from one to four years 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 $0.0594 and the weighted average fair vaoue of the options on the dates of grant was $0.0591. The estimated fair value of the options was determined using the Black-Scholls pricing model using the following assumptions: Expected term: Volatility: 10 years 180-184% Dividend yield: 0.00% Risk-free interest rate: 2.24-2.32% Warrants At December 31, 2015, the Company had two outstanding warrants to purchase a total of 2,500,000 shares of common stock at an exercise price of $0.08 per share. Unless exercised, warrants to purchase 2,187,500 shares will expire on January 10, 2016 and warrants to purchase 312,500 will expire on June 4, 2016.

No warrants expired during the period ending December 31, 2014. NOTE 3 – Registration Statement on Form S-3 As previously reported, during September 2014, the Company filed a Registration Statement on Form S-3 with the SEC, which was declared effective by the SEC on December 19, 2014. The Company may offer and sell, from time to time, up to $100,000,000 of securities, including shares of the Company's common stock and preferred stock, debt securities and warrants, either individually or in units, the terms of which will be described in prospectus supplements filed with the SEC, as applicable. Concurrently with the filing of the Registration Statement, the Company entered into an At The Market Offering Agreement, or sales agreement, with Ascendiant Capital Markets, LLC (“Ascendiant”), pursuant to which the Company may offer and sell from time to time through Ascendiant, acting as sales agent and/or principal, shares of our common stock having an aggregate offering price of up to $25,000,000. We have agreed to pay Ascendiant a commission rate of 3% of the gross sales price per share of any of our shares of common stock sold through Ascendiant, as agent, under the sales agreement. The offer and sale of our shares through Ascendiant will be registered pursuant to the Registration Statement. As of December 31, 2015, no securities have been sold under the Registration Statement. As of December 31, 2015, the Company was not eligible to use the Registration Statement because the aggregate market value of the Company’s outstanding common stock held by non-affiliates of the Company was less than the minimum required by General Institution I.B.1 of Form S-3 (i.e., $75 million) F-11 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 developing new product lines to increase future revenues. The Company believes it has adequate working capital and cash to fund operations through 2016, 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, 2015, unused operating loss carryforwards of approximately $6,131,324, 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 $2,914,526 and $2,255,520 at December 31, 2015 and 2014, respectively, and, therefore, no deferred tax asset has been recognized for the loss carryforwards. The change in the valuation allowance is approximately $659,006 and $1,210,597 for the years ended December 31, 2015 and 2014, respectively. Deferred tax assets are comprised of the following: Deferred tax assets: NOL carryover Impairments Warrants Valuation allowance Net deferred tax asset 2015 2014 $ $ 2,382,020 33,931 498,575 (2,914,526) - $ $ 1,723,014 33,931 498,575 (2,255,520) - F-12 The reconciliation of the provision for income taxes computed at the U.S. federal statutory tax rate (34%) to the Company’s effective tax rate for the period ended December 31, 2015 and 2014 is as follows: Book Loss State taxes Deductible differences Change in valuation allowance Provision for Income Taxes NOTE 6 – Loss Per Share 2015 2014 $ $ $ 576,736 82,270 - (659,006) 1,059,467 151,130 - (1,210,597) - $ - The following data show the amounts used in computing loss per share and the effect on income and the weighted average number of shares of dilutive potential common stock for the periods ended December 31, 2015 and 2014: Loss from continuing Operations available to Common stockholders (numerator) Weighted average number of common shares Outstanding used in loss per share during the Period (denominator) Year Ended December 31 2015 2014 $ (1,696,282) $ (3,116,080) 622,810,776 610,344,691 Dilutive loss per share was not presented as the Company had no common equivalent shares for all periods presented that would affect the computation of diluted loss per share or its effect is anti-dilutive.

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. F-13 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. The following is a summary of definite-life intangible assets less accumulated amortization as of December 31, 2015 and 2014, respectively: Provisional Patent Applications Patents Customer Contacts Less: Accumulated Amortization Net Intangible Assets Year Ended December 31, 2015 2014 $ $ $ 137,927 39,252 262,009 (271,544) 63,823 39,252 262,009 (269,237) 167,644 $ 95,847 Amortization expense on intangible assets was $2,308 and $2,309 for the years ended December 31, 2015 and 2014.

The Operating Agreement and Statement of Work govern 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 hold a 50% ownership interest in the Joint Venture, and (ii) the Joint Venture is managed by William F. Herman, President of Arete, subject to certain limitations. Based on the Operating Agreement, the Company holds the non-controlling interest in the Joint Venture. Therefore, the Joint Venture has not been consolidated, but rather is accounted for on the equity method of recording investments. During the year ended December 31, 2015, net operations resulted in a loss on the investment of $778. The Company intends to terminate the Joint Venture in the first half of 2016, but is continuing to pursue business opportunities related to AM utilizing the Company's EOS M290 or like machines.
