Laser Powder Bed Fusion of Chromium Bronze Using Recycled Powder [PDF]

open access: yesMaterials, 2021
Laser powder bed fusion (LPBF) of Cu-0.5Cr was carried out using recycled powder taken out from the LPBF machine after previous printing. Various volumetric defects characterized the powder wherein particle size distribution was the same as virgin powder. Using recycled powder resulted in extra spherical pore formation after the LPBF process.
