Additive manufacturing powder spreading technology to mitigate surface defects
Patent
·
OSTI ID:1859926
A laser powder bed fusion additive manufacturing system having a powder dispenser that provides powder layers on a build platform; a laser fusion system that fuses the powder layers, wherein spatter particles are produce on the powder layers; and a powder bed sweeping system that sweeps the spatter particles from the powder layers. The powder bed sweeping system includes a brush that has bristles that contact the spatter particles and sweeps the spatter particles from the powder layers.
