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.

Independent laser-beam steering for laser beamforming in metal additive manufacturing using powder-bed fusion

A method of metal additive manufacturing includes generating a plurality of laser beams and directing the plurality of laser beams to selected portions of a surface of a powder bed of powdered metal. The method also includes monitoring the powder bed while performing the generating and directing, and adjusting at least one of the generating or directing based on the monitoring.
