Independent Laser-Beam Steering for Laser Beamforming in Metal Additive Manufacturing Using Powder-Bed Fusion

Abstract

A metal additive manufacturing system includes a powder bed for powdered metal, a plurality of lasers to generate a plurality of laser beams, and a plurality of scanners to independently steer respective laser beams of the plurality of laser beams into laser-beam clusters on selected portions of a surface of the powder bed. A method of metal additive manufacturing includes generating a plurality of laser beams and independently steering respective laser beams of the plurality of laser beams, using a plurality of scanners, to form laser-beam clusters on selected portions of a surface of a powder bed of powdered metal. Each scanner of the plurality of scanners independently steers a respective laser beam of the plurality of laser beams.
