Sigma Labs Inc. (NASDAQ: SGLB) is a leading producer of quality assurance software for the commercial 3D-printing industry. The company is about to revolutionize commercial 3D printing metal by enabling nondestructive quality assurance during the production process. Sigma Labs’ proprietary PrintRite3D software is a real-time, computer-aided inspection (CAI) technology long sought by 3D printing companies to lower costs and increase yields. PrintRite3D represents a breakthrough in the 3D-quality inspection sphere because it is the only known real-time, in-process, quality-assurance software for the commercial 3D metal printing industry.

3D printing, also called additive manufacturing, is a technology that allows producers to transform a 3D digital model of an object into a physical one by adding material rather than subtracting it, hence the additive in the name. The resulting 3D objects are made in a digitally controlled and operated process by depositing minuscule layers of material onto a substrate layer.

The technology has been embraced by commercial users, especially aerospace. The technology allows companies to build digital designs, push ‘Send’ and render fully formed prototype, customized products or commercial parts in volume – all while saving money, manpower, weight and time. However, the technology is facing hurdles in finding its way beyond prototyping and into conventional manufacturing and serial production. The reason? Before 3D printing metal can be fully integrated into modern manufacturing lines, technology is needed to resolve significant issues such as optimized data handling as well as real-time quality assurance process, monitoring and control.

Due to variances in the 3D-printing process, consistent quality of produced parts can’t be reliably achieved without considerable postproduction inspection that results in high rejection costs. Because parts are inspected after production using expensive CT scans, the manufacturer doesn’t know until the end of the process which of the finished parts meet design specifications. This results in lost time, lost profits and inability to economically scale up production.

This is where Sigma Labs steps in. The company’s people, processes and technologies are pioneers, about to transform the nascent 3D-printing sector by enabling SGLB’s rapid, efficient commercial applications and allowing growth at scale. Unlike any other quality-inspection software in the market, PrintRite3D is a third-party, validated software that enables real-time monitoring, analysis, feedback and control during the 3D-printing process of precision metal parts. The software conducts thermal-signature anomaly detection and automatic risk-level classification through statistical process sampling and advanced analytics.

This innovative solution is based on a proactive, comprehensive, process-focused methodology that enables prediction of product conformance to predefined acceptance requirements. More simply, PrintRite3D discovers defects during the production while adjusting the process in real-time to correct them. This unique solution leads to faster production of metal parts with fewer errors and a more uniform product resulting in decreasing downtime and waste while increasing yield and profits for 3D-printing companies.

3D printing is an innovative technology that has seen growing interest from manufacturers and investors alike stemming from decreasing product lifecycles trend, which is influenced by factors such as increased global competition and the need for innovation due to saturated markets and changing customer demands. Additive-manufacturing technology is viewed as a response to these challenges as it considerably reduces time to market.

According to Verified Market Research, the global 3D-printing market was valued at $8.08 billion in 2017 and is expected to grow at a CAGR of 25.5% from 2018 to 2025, reaching the value of $49.74 billion (http://nnw.fm/Hw0fh). Given these impressive growth rates, investors have been investing heavily in 3D-printing companies now that their commercial applications are soaring. The sector has already produced three unicorns, with the highest valued being Carbon, a 3D-printing, venture-backed startup that has raised $680 million, at a valuation of $2.4 billion, from investors such as Sequoia Capital, Madrone, Baillie Gifford Capital Partners and GV.

Sigma Labs was founded in 2010 and has since become the go-to, 3D-printing expert for real-time, computer-aided inspection (CAI) solutions. Managed by experts from many different science disciplines such as metallurgy, physics, signal processing, mechanical engineering, optics, software AI and ML, data analytics and visualization, the company established credibility within highly demanding industries such as aerospace, defense, biomedical and transportation.
