WIPO Patent Application WO/2017/212619

A1

The present invention is an additive manufacturing control device that corrects a laser irradiation position in response to changes in the laser irradiation position during additive manufacturing with a stereolithography apparatus. The additive manufacturing control device controls an additive manufacturing unit that manufactures an additively manufactured object and that is provided with a squeegee blade for blanketing a layering material upon the top layer of the additively manufactured object and an irradiation unit for irradiating the layering material. The additive manufacturing control device is equipped with a misalignment acquisition unit for acquiring the misalignment of the irradiation position of the irradiation light on the surface of the squeegee blade that receives the irradiation light from the irradiation unit, and an irradiation position correction unit for correcting the irradiation position from the irradiation unit on the basis of the misalignment.
