摘要
Systems and methods additively manufacturing an object by applying heat to a first plurality of metallic particles in a powder bed using a first heat source, wherein the first heat source is one of multiple heat sources configured into an array, and the first heat source generates a first melt pool. Heat is simultaneously applied to a second plurality of metallic particles in the powder bed using a second heat source of the multiple heat sources in the array to generate a second melt pool. The first plurality of metallic particles are separated from the second plurality of metallic particles by a distance, wherein the distance and an amount of heat from each heat source is controlled to generate a combined melt pool that is larger in size and encompasses the first and second melt pools. The combined melt pool is allowed to solidify to form the object.
