摘要： Methods of additively manufacturing a three-dimensional object by one or more energy beams include selectively directing a first energy beam across a powder bed along a plurality of first hatching paths and a first contour path that defines a first outer contour portion and a first stitching portion, wherein the first outer contour portion at least partially defines a first edge portion of an outer edge of the three-dimensional object, and wherein the first edge portion is non-linear, and selectively directing a second energy beam across the powder bed along a plurality of second hatching paths and a second contour path that at least partially defines a second edge portion of the outer edge of the three-dimensional object, wherein the second edge portion is adjacent the first edge portion, and wherein the first stitching portion extends into the plurality of second hatching paths along a non-linear stitching path.
