Performance of eddy currents for the in-situ detection of defects during PBF-LB metal AM
In this joint study by Carl Zeiss AG, AMiquam SA, and EOS GmbH, the performance of eddy currents as a tool for the in-situ detection of defects in Laser Beam Powder Bed Fusion (PBF-LB) has been assessed. Process variations, including lack of fusion and keyhole formation could be detected in-situ, as well as individual defects as small as 0.3 mm post-build and post-polishing. Here, Jonatan Wicht, Harald Krauss, Frank Widulle, Julian Schulz, and Edson Costa Santos, Alain Berthoud, and Bernard Revaz present their latest findings. ... Read more »
