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.

摘要： A method of additively manufacturing an object may include defining an interlace path for a plurality of energy beams from an energy beam system based at least in part on a route-finding algorithm. The interlace path may delineate a first contour zone of a build plane assigned to a first one of the plurality of energy beams from a second contour zone of the build plane assigned to a second one of the plurality of energy beams. An exemplary method may additionally or alternatively include outputting a control command based at least in part on the interlace path. The control command may be configured to cause the energy beam system to irradiate a layer of a powder bed with the plurality of energy beams.
