Multi-Scanner On-the-fly Processing for Laser Powder Bed Fusion

Video / November 20, 2019

In the scope of the Fraunhofer lighthouse project futureAM, scientists from Fraunhofer ILT have developed an enhanced processing strategy for Laser Powder Bed Fusion (LPBF). A multi-scanner processing head with five laser-scanner-systems was integrated into Fraunhofer ILT’s prototype LPBF machine with a maximum build envelope of 1000 mm x 800 mm x 500 mm. In order to increase the system’s productivity, a synchronized movement of the galvanometer scanners and the linear axis system was realized enabling on-the-fly processing.
