Laser Powder Bed Fusion Using Diode Lasers

Описание: High-power diode lasers exhibit interesting properties for use in Additive Manufacturing. However, due to their comparably low beam quality, diode lasers are challenging to integrate into conventional scanner-based LPBF-machines. As part of the Fraunhofer lighthouse project “futureAM” a LPBF-machine setup combining an industrial high-power diode lasers, a galvanometer scanner and a custom f-theta lens was developed and validated for the processing of stainless steel (AISI 316L). This approach yields comparable part properties and machine productivity as conventional fibre laser based LPBF-Systems.
