Thanks. This is from the October 2019 issue of 'Aerospace Manufacturing and Design.'

Sigma Labs was also covered by them in the June 2019 issue.

Sigma Labs Metal AM technology receives quality-assurance validation

PrintRite3D technology developed by Sigma Labs Inc. has proven process consistency and product quality in metal additive manufacturing (AM), according to a research study sponsored by the Defense Advanced Research Project Agency (DARPA) Open Manufacturing Program and conducted with Honeywell Aerospace at Honeywell’s Advanced Manufacturing Engineering Center. Details of the study were published in the journal Integrating Materials and Manufacturing Innovation.

Sigma Labs CEO John Rice says, “Our 6-year research with Honeywell and the DARPA Open Manufacturing Program demonstrates that the analysis of the thermal emission density (TED) metric made by our technology can play a critical role in ensuring quality in industrial AM of metal parts. DARPA’s conclusion that Sigma’s technology can be used for certifications and/or certification of components of 3D metal parts has significant positive implications to advance wide-scale industrialization of metal AM.”

Sensors used in the TED in-process quality metric monitored the component’s porosity as it was being built.
