Improving the Surface Quality of Laser Powder Bed Fusion Parts

Surface quality and geometrical precision of parts manufactured by laser powder bed fusion (LPBF) are often insufficient for their final application. This work presents insights into the LPBF process and shows some possible means of improving the quality of up- and down-facing surfaces, as well as elevated edges of the part. The presented results were achieved by multiple work groups from the Precision Additive Metal Manufacturing (PAM^2) consortium, namely the Additive Manufacturing and Manufacturing Metrology team at KU Leuven, and 3D Systems Leuven.status: Published onlin
