A group of Chinese and U.S-based researchers have discovered a Powder Bed Fusion (PBF) 3D printing ‘speed limit’ at which part defects are less likely to occur. Through extensive X-ray im…
Carnegie Mellon University and Argonne National Laboratory unlock keyhole phenomenon in metal 3D printing
In a recently published paper, scientists from Carnegie Mellon University and Argonne National Laboratory used high-speed x-ray imaging to study the keyhole effect in powder-based metal 3D printing. A…
