(レーザー関連)Green laser melts pure copper

Fraunhofer IWS applies innovative laser melting system for
complex copper components for the first time

(Dresden, August 13, 2020) Creating sophisticatedly shaped plastic parts with the 3D printer is no longer an art process, but an everyday technology. This is quite different with pure copper: Until now, it has not been possible to completely melt the metal to create complex components layer by layer using infrared lasers. As a result, the Fraunhofer Institute for Material and Beam Technology IWS in Dresden is now using a novel additive manufacturing system, which processes the metal almost defect-free with a short-wave green laser. It enables new production approaches which previously could not be realized with pure copper. Thus, complex components made of pure copper and copper alloys can be realized for aerospace and automotive industry and the efficiency of electric motors and heat exchangers can be increased.
