About Sigma Labs, INC.

SIGMA LABS, INC. is a U.S.-based technology company listed on the NASDAQ market under the ticker SGLB, making it a name that typically attracts investors focused on U.S. small-cap growth and special-situation equities. Headquartered in the United States, the company has built its identity around a highly specialized niche: software for quality assurance in metal additive manufacturing. That niche matters because industrial 3D printing is increasingly judged not only by speed and design flexibility, but by whether parts can be produced consistently, documented reliably, and certified for critical applications. The company’s history reflects a classic science-to-commercialization path. SEC filings describe Sigma Labs as having been founded by scientists, engineers, and business professionals with the goal of developing and commercializing novel manufacturing and materials technologies. Over time, the business evolved from an R&D-oriented organization into a more commercially focused industrial software company. Earlier corporate history shows the company operating under the former name Framewaves, Inc., before becoming Sigma Labs, Inc., and later moving onto the NASDAQ Capital Market as part of its capital-markets and commercialization strategy. Sigma Labs’ core product is PrintRite3D, its in-process quality assurance, or IPQA, platform. The software is designed to monitor additive manufacturing processes in real time, support defect detection, improve repeatability, and create traceability for production environments where quality standards are stringent. In practical terms, that positions Sigma Labs as a software-enabled quality layer for manufacturers producing mission-critical metal parts. The strongest end markets tend to be aerospace, defense, industrial manufacturing, energy, and advanced engineering applications, where process control can be just as important as machine throughput. From a competitive standpoint, Sigma Labs operates in a specialized segment with meaningful technical barriers. Success depends on software performance, integration with OEM ecosystems, and the ability to demonstrate operational value to industrial customers. The company has historically emphasized collaborations and validations with major industry participants, which have helped establish credibility for its technology in a market still moving from early adoption toward broader industrial deployment. Geographically, Sigma Labs’ footprint remains primarily centered in the United States, although the nature of additive manufacturing gives the company potential access to international customers through OEM relationships and global industrial supply chains. Recent public updates have continued to focus on commercial adoption of PrintRite3D, customer engagements, and the broader transition from development-stage credibility to scalable software commercialization. For investors, Sigma Labs remains a high-risk, high-upside technology story tied to the pace at which metal additive manufacturing becomes a mainstream industrial production tool.
