Sigma Labs Demonstrates Proof of Concept for Closed Loop Quality Control During Metal Additive Manufacturing
May 30 2018 - 8:00AM
Sigma Labs, Inc. (NASDAQ:SGLB) (“Sigma Labs” or the “Company”), a
provider of quality assurance software under the PrintRite3D®
brand, today announced that the Company has developed and
demonstrated closed-loop feedback control of the metal laser powder
bed fusion 3D printing process. Using Sigma’s PrintRite3D®
technology, the system operates by monitoring the process output
and extracting process metrics. The process metrics are then
compared to baseline metrics. The system then determines what
process input parameter values need to be changed and implements
those remedial changes in real time by signaling a change in the
laser power in order to maintain the process under control.
Mark Cola, Chief Technology Officer of Sigma Labs, stated,
“Automatic feedback process control was the next step in completing
Sigma Labs’ suite of sensing, monitoring, and control capabilities
of metal additive manufacturing (AM) processes. Our addition of
real-time process control clearly sets Sigma as the leader in AM
process quality assurance.”
Cola further stated, “By achieving this advanced understanding
of quality variation and machine learning for metal AM machines
that the Factories of the Future require, Sigma Labs has
demonstrated that it is possible to bring the future to the
present.”
Sigma Labs has patents pending covering its closed loop control
of melt pool quality during metal AM using its PrintRite3D®
technology. Sigma is planning beta testing with select, end-user
customers across various market segments.
