Sigma labs also installed a position sensor in-line with the command signal coming from the EOS computer to the scan head to capture and record x-y position information of the laser. Such data is used to correlate laser position information with IPQM®” data generated withSigma’s PrintRite3D software. Therefore, allowing the capability to monitor the build throughout the full bed.

T&L,

Thanks much for this post. It's continued confirmation that PrintRite3D does work as anticipated. Any doubt about correlating Sigma's metrics to actionable data should be erased with this whitepaper and I quote

This work has demonstrated that a combination of physics based modeling and experimental verification and validation can enable early stage identification and elimination of potential problems. The build was directly successful and component testing confirmed achievement of the targeted porosity, geometric accuracy, and mechanical strength of the printed material. It has shown that the qualification framework presented here can be used as the compliance means for certifications and/or certification of components.

The involvement of SGLB in the ICME framework has been huge in my mind. That ICME framework with SGLB in the middle caught my eye back in 2015 I quote" That AM ICME framework has HUGE potential for SGLB as the IPQA may be built into the framework."https://investorshub.advfn.com/boards/read_msg.aspx?message_id=115888768

I look forward to SGLB figuring out how to capitalize on the involvement in this DARPA project. I hope that JR will be able to take advantage of this confirmation in SGLB.
BTW I like this quote from the whitepaper as well [quote]When in-process data collected from the photo diode is mined for features and fused to derive in-process quality metrics™ (“IPQM®s”), a complete understanding of part quality and of process control can be obtained.

Good Luck All
