Thermal Calibration of Commercial Melt Pool Monitoring Sensors on a Laser Powder Bed Fusion System

Sigma recently collaborated with NIST to outline how to calibrate PrintRite3D® sensors to a traceable temperature standard. As a result, Sigma has performed a first-ever standards calibration with the renowned National Institute of Standards and Technology. This now opens the door to machine-to-machine calibration and enables machine matching for the Additive industry. Sigma Additive Solutions is achieving the milestones necessary for certification and industry-wide acceptance and has become a lead author in developing the melt pool monitoring standard within the ASTM international framework which is expected to go to ballot in Q4 2020. This enables a pathway to adoption by additional international standard bodies such as ISO and JSA in 2021.
