Researchers offer new explanation for shrinkage porosity in laser beam powder bed fusion 3D printing 

Researchers from Carnegie Mellon University and the University of Pittsburgh have released a new explanation for defects in laser beam powder bed fusion (PBF-LB).   The researchers’ work focuses on the occurrence of shrinkage porosity in Inconel Alloy 718 during PBF-LB 3D printing. Shrinkage porosity is a common defect in metal casting, and forms when metal […]
