Sigma Labs Inc. (NASDAQ: SGLB) Delivers Proprietary Technology to Solve Quality, Reliability Challenges in 3D Metal-Printing

• Sigma Labs allows companies to build, qualify, and certify parts more quickly and at lower cost
• Before Sigma, no quality metric existed for melt pool monitoring, in situ monitoring, or process quality control that provided in process alerts and solutions

As additive manufacturing – or 3D metal printing – gains traction in the manufacturing world, the problems with the technology have hampered production and stymied large-scale uptake. Sigma Labs Inc. (NASDAQ: SGLB), a leading producer of quality-assurance software for the commercial 3D-printing industry, is committed to providing answers to those problems in the latest version of its proprietary technology.

“For some engineers, 3D printing may be coming on in an unwelcome rush,” stated a recent Engineering.com article, titled ‘7 Issues to Look Out for in Metal 3D Printing’ (http://nnw.fm/rL6G7). “Avoiding issues in metal AM still requires a lot of process knowledge and trial and error,” the article states, denoting how critical it is for operators to monitor processes in real-time—a problem for which SGLB’s PrintRite 3D software offers a solution.

In its own article (http://nnw.fm/bZ6ua), ‘What Is Metal Additive Manufacturing’, Sigma Labs also acknowledges that “the large-scale adoption of direct 3D metal additive manufacturing faces quality and reliability challenges.” Those challenges are outlined in the article as follows:

• The machines and processes are inherently variable – machine to machine and within machine – causing variation in manufacturing and production consistency.
• The build process itself has many adjustable inputs that directly affect the ability to create a part and its final quality.
• The industry has few design rules, monitoring methods or standards for finished products.
• There is difficulty ensuring consistent, repeatable quality for final production parts.

In what it calls the “Sigma Solution,” Sigma Labs argues that its IPQA™ technology accurately monitors the quality and reliability of additive manufactured parts by ensuring consistent quality control during the manufacturing process. Until now, optical monitoring systems have recorded the manufacturing process but have been unable to deliver actionable in-process information to enable the rescue of parts straying out of specification. Additionally, parts could only be fully quality inspected post-production in costly and time-consuming processes and only after the mistakes were made. Sigma’s real-time melt pool analytics software frees manufacturers to build, qualify and certify parts more quickly and at a much lower cost.

Sigma’s proprietary software reduces the traditional post-production quality assurance inspection process for additive manufacturing; helps ensure the quality of each part; dramatically reduces costs and labor associated with the current approach to certifying AM part quality by “seeing” and analyzing the structure of a 3D-printed part during production; and allows for correction during the manufacturing process.

Sigma Labs was founded in 2010 and has become the go-to, 3D-printing expert for real-time, computer-aided inspection (CAI) solutions. Founded by experts from scientific disciplines that include metallurgy, physics, signal processing, mechanical engineering, optics, software AI and ML, data analytics and visualization, the company has already established credibility within highly demanding industries such as aerospace, defense, biomedicine and transportation. Sigma Labs’ revolutionary technology is set to unleash the powerful forces of 3D metal printing, changing the face of the industry by increasing reliability, lowering quality control costs and enabling serial manufacturing.
