SCAN FIELD VARIATION COMPENSATION

Abstract:

A method, apparatus, and program for additive manufacturing. In one aspect, the additive manufacturing method includes irradiating a build material (416) to form a first solidified portion within a first scan region (812A) using an irradiation source (401) of a build unit (400). At least one of the build unit and a build platform may be moved to irradiate a second scan region (812B), wherein an irradiation source (401) directing mechanism is adjusted to compensate for a misalignment between the first scan region and the second scan region (640).
