Microstructure and Mechanical Properties of Laser Powder Bed Fusion 3D-Printed Cu-10Sn Alloy

Journal of Powder Materials
This study investigated the optimal process conditions and mechanical properties of Cu-10Sn alloys produced by the powder bed fusion (PBF) method. The optimal PBF conditions were explored by producing samples with various laser scanning speeds and laser power. It was found that under optimized conditions, samples with a density close to the theoretical

MAR-M247 Ni-based superalloy metal 3D printing with Electron Beam Powder Bed Fusion

Abstract This study explores the influence of scanning strategies on microstructure evolution using electron beam powder bed fusion (EB-PBF) of MAR-M247, a Ni-based superalloy. An energy density that produces minimum cracking was established by raster melting, and subsequently applied to spot melting to investigate how spot melting strategy ...
