Classification: CPC B  Y | IPC B

Claim 9:
10. A method of fabricating a component in a powder bed comprising:
emitting a plurality of energy beams from a plurality of laser devices of a laser array;
inducing, by an optical element, a power diffusion in at least one energy beam of the plurality of energy beams providing a diffused energy beam;
generating a melt pool, at least in part, with the diffused energy beam;
producing, by the plurality of laser devices, a plurality of beam spots defining a beam spot pattern having a beam spot pattern length, each beam spot of the beam spot pattern corresponding to a respective energy beam;
elongating, by the power diffusion, at least one of the beam spots in a direction that is at least one of substantially parallel and substantially perpendicular to the beam spot pattern length; and
varying the power diffusion along the beam spot pattern length.
