Classification: CPC B  Y | IPC B

Claim 2:
3. 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 to providing a diffused energy beam;
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 a respective energy beam; and
diagonally elongating, by the power diffusion, at least one of the beam spots relative to each of the beam spot pattern length and the beam spot pattern width.
