Mutual comparison of acoustic, pyrometric and thermographic laser powder bed fusion monitoring
Authors: Contents:- The process monitoring capabilities of three distinctive sensors (XARION’s optical microphone, a pyrometer and a thermographic camera) were compared for laser powder bed fusion metal additive manufacturing
- The optical microphone presents a sensitivity up to 40 times higher than the thermographic camera and is 15 times more sensitive than the pyrometer
