Claim 0:
1. A method for additively manufacturing an object, the method comprising:
applying heat to a first plurality of metallic particles in a powder bed using a first heat source, the first heat source being one of multiple heat sources configured into an array, the first heat source generating a first melt pool;
simultaneously applying heat 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 separated from the second plurality of metallic particles by a distance, wherein the second melt pool is adjacent and parallel to the first melt pool, and the distance and an amount of heat from each heat source is to be controlled to generate a combined melt pool that is larger in size and encompasses the first melt pool and the second melt pool; and
allowing the combined melt pool to solidify to form the object, wherein residual heat stored within parallel melt pools allows the parallel melt pools to merge before solidification occurs.
