Interlace calibration and methods of use thereof

Abstract:

A method, apparatus, and program for calibrating an additive manufacturing apparatus. In one aspect, a method is disclosed for calibrating an additive manufacturing apparatus. The method includes forming a first solidified portion within a first scan region, wherein the solidified portion within the first scan region is formed by irradiating a build material while a build unit is in a first location. The method further includes forming a second solidified portion within a second scan region, wherein the second solidified portion within the second scan region is formed by irradiating a build material while a build unit is in a second location different from said first location. An alignment of the additive manufacturing apparatus determined based on the detected alignment of the first solidified portion and the second solidified portion.
