the IPQA metrics were discovered to be a weak predictor of porosity. They were also found to be a limited predictor of ultimate tensile strength and fracture toughness with evaluation of the latter somewhat limited by a small sample size. The program results provided data on the material properties that were researched and discovered to not be reliably related to the IPQA process, laying the groundwork for future investigation into other new tools and approaches for in-process monitoring of laser powder bed additive manufacturing.

Sigma Labs worked with the aerospace OEMs (GE Aviation, Honeywell International, and Aerojet Rocketdyne) to transition the IPQA technology into the preproduction environment at each of their facilities. PrintRite3D IPQA systems were installed at GE Aviation and Aerojet Rocketdyne while testing for Honeywell was completed using a PrintRite3D IPQA system at the Sigma Labs facility. To assist with development and commercialization efforts, the OEMs provided guidance in drafting functional and operational requirements for the technology.
