文摘

A novel highly scalable multi-laser powder bed additive manufacturing approach for processing metallic alloys. Near full melting of stainless steel alloy powder (99.7% density) using customised low power diode emitters (2.63 W). Increased laser absorption and reduced laser power requirement through use of shorter laser wavelength.
