Scanning strategy for perimeter and region isolation

A non-transitory computer readable medium comprising computer-executable instructions, which when executed by a processor associated with an additive manufacturing machine, cause the additive manufacturing machine to execute an additive manufacturing method, the manufacturing method comprising:

• forming an at least partially solidified portion within a first scan region, wherein the solidified portion within the first scan region is formed by irradiating a build material at a first energy density value along a first irradiation path;
• forming an at least partially solidified portion 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, wherein 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.
