Patent attributes
A method, apparatus, and program for additive manufacturing. In one aspect, the method and program comprises forming an at least partially solidified portion within a first scan region by irradiating a build material at a first energy density value along a first irradiation path. A second at least partially solidified portion is formed within a second scan region that is spaced with respect to the first scan region, wherein the solidified portion within the first scan region is formed by irradiation a build material at a second energy density value along a second irradiation path. The space between the first scan region and the second scan region is at least partially solidified by irradiating a build material at a third energy density value that less than the first energy density value and the second energy density value.
