Classification: CPC B  Y | IPC B

Claim 0:
1. 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; and
generating a melt pool, at least in part, with the diffused energy beam, wherein:
emitting the plurality of energy beams produces a plurality of beam spots defining a beam spot pattern having a beam spot pattern length and a beam spot pattern width, each beam spot of the beam spot pattern corresponding to one of the energy beams, and
inducing the power diffusion elongates at least one of the beam spots in a direction that is at least one of substantially parallel to the beam spot pattern length and substantially parallel to the beam spot pattern width.
