develops and engineers advanced, in-process, non-destructive quality inspection systems for commercial firms worldwide seeking productive solutions for metal-based additive manufacturing or 3D printing, and other advanced manufacturing technologies. Sigma has a proud Los Alamos legacy and a future rooted in bringing advanced materials and processing solutions to clients worldwide. It was founded in 2005 by high-level scientists from the world-renowned Los Alamos National Lab. The company went public in 2010 with the commercialization of the breakthrough PrintRite3D® system. Just as Los Alamos helped shape the modern world in the 20th century, Sigma Labs is bringing to market advanced manufacturing, materials and process monitoring technologies that will serve our clients in many ways.

Our team of leading scientists and engineers from Los Alamos National Laboratory have over 100 years of combined industrial R&D experience. We develop manufacturing and materials technologies and R&D solutions for first-tier integrators like Boeing, GE Aviation, Honeywell Aerospace, and other commercial firms around the globe. Sigma Labs has current contracts with Federal Government and private industry clients to develop technologies from their conception through the design, building, and testing of prototype systems by integrating sensing, software, materials, and manufacturing technology risk-reduction solutions.
