Sigma Labs, Inc., a provider of quality assurance software under the PrintRite3D brand, has announced that the U.S. Patent and Trademark Office has issued a Notice of Allowance for U.S. Patent Application No. 15/276,452, “Optical Manufacturing Process Sensing and Status Indication System.” The patent application covers a system of sensors configured to measure optical emissions generated by a scanning heat source during an additive manufacturing (AM) process and to analyze the data collected.

John Rice, CEO of Sigma Labs, said, “This patent allowance further enhances the depth and breadth of the patented intellectual property portfolio covering our PrintRite3D platform. The technology covered in this patent enables Sigma to provide valuable and relevant quality status information to customers requiring high-quality AM metal products production. The USPTO has now allowed four patents pertaining to Sigma Lab’s PrintRite3D® platform, representing a wide degree of innovation and distinguishing us as a leader in this space. Additionally, there are eighteen more patents-pending in process.”

Mr. Rice concluded, “Sigma’s patent portfolio, our newly launched platform, and our recently signed agreements cumulatively represent what we believe is a formidable and valuable initiative through which we can more easily work with customers that need to secure a greater measure of repeatable high-quality yields and efficiency in the serial AM production of metal components.”

Sigma Labs provide in-process control and quality assurance software for Additive Manufacturing. Sigma’s interactive system combines inspection, feedback, data collection and critical data analysis for management of AM processes. The system pairs PrintRite3D Sensorpak multi-sensors and hardware with PrintRite3D INSPECT and PrintRite3D CONTOUR software modules for comprehensive management and control of AM processes.
