摘要： A component is fabricated in a powder bed by moving a laser array across the powder bed. The laser array includes a plurality of laser devices. The power output of each laser device of the plurality of laser devices is independently controlled. The laser array emits a plurality of energy beams from a plurality of selected laser devices of the plurality of laser devices to generate a melt pool in the powder bed. A non-uniform energy intensity profile is generated by the plurality of selected laser devices. The non-uniform energy intensity profile facilitates generating a melt pool that has a predetermined characteristic.
