Sigma Labs Awarded PrintRite3D Upgrade Contract with Leading Industry Research Institute Fraunhofer IAPT

Early Adopter and Leading Institute for Development of Industrial Solutions in Additive Manufacturing to Upgrade to PrintRite3D Version 5.1

SANTA FE, NM / ACCESSWIRE / November 20, 2019 / Sigma Labs, Inc. (NASDAQ:SGLB) ("Sigma Labs"), a leading developer of quality assurance software for the commercial 3D printing industry, has been awarded a contract by the Fraunhofer Research Institution for Additive Manufacturing Technologies (IAPT), an additive manufacturing research innovator and early adopter of PrintRite3D®, to upgrade its current version PrintRite3D system to version 5.1.

Sigma Labs and Fraunhofer IAPT continue to strengthen their long-standing relationship and collaboration to establish PrintRite3D as the benchmark process monitoring system for the laser beam melting processes that have established Fraunhofer IAPT as a leader in the field. In an earlier announcement, Sigma Labs and Fraunhofer IAPT announced a collaborative research and development agreement to test and validate the use of the PrintRite3D's In-Process-Quality-Assurance suite to identify and quantify machine and process inconsistencies as well as to define in-process defect thermal signatures in the part formation process and correlate them to CT scan results.

The single-machine contract award will launch a series of software and hardware updates to upgrade the legacy PrintRite3D system to the current version 5.1 system. Sigma Labs is a member of the Fraunhofer IAPT-headed Additive Alliance, a global research consortium to advance the development and implementation of additive manufacturing.

"Fraunhofer IAPT is an undisputed thought leader, advancing the additive manufacturing industry through the incredible research work it does every day," said John Rice, CEO of Sigma Labs. "Through the material progress accomplished in our relationship and its utilization of our latest PrintRite3D technology, I'm confident that together we will establish valuable industry relationships throughout Europe and create long-term value for our shareholders," concluded Rice.

Integrating inspection, feedback, data collection and critical analysis into a unified platform, PrintRite3D Version 5.1:

  • Mines and identifies thermal signatures of melt pool disturbances and respective discontinuities using thermal emission spectroscopy;
  • Harnesses Co-Axial Planck Thermometry to provide a verified thermal signature in both temperature and coordinates;
  • Uses In-Process Quality Metrics™ (IPQMs®), Thermal Emission Density (TED™) and Thermal Emission Planck (TEP™) to analyze internal thermal signatures and melt pool disturbances;
  • Contains a graphical user interface for real-time display of live part quality results and Automated Anomaly Detection on thermal mapping images providing location and anomalous region size;
  • Collects data with fixed spatial resolution in the X/Y plane but variable resolution depending on layer height used during the manufacturing process; and
  • Is platform-independent and available as a third-party add-on or retrofit package for existing machines.

PrintRite3D is Sigma Labs' patented in-process quality assurance software for the commercial 3D metal printing industry, providing real-time melt pool analytics. The software uniquely leverages thermal signatures to monitor the quality of each product part in the production process, layer by layer and in real-time, allowing operators to correct or stop production of a defective part - resulting in reduced error rates and higher yields. The software is currently being evaluated by tier-1 aerospace and OEM partners worldwide.
