摘要

The present invention is a three-dimensional additive manufacturing system that shortens the scanning time of a divided scanning region and reduces the modeling time of three-dimensional additive manufacturing. This three-dimensional additive manufacturing system has at least one irradiation unit that irradiates a laminate material, and an additive unit that models each layer of an additive manufacturing object made of the laminate material as a set of cell regions, and a cell region by the irradiation unit. The shape of the scanning region for irradiation is a shape including at least five vertices having an inner angle of 90 degrees or more, and the irradiation material scans in a spiral shape along the side of the scanning region to form a laminated material in the cell region. An additive manufacturing control unit that controls the additive manufacturing unit so as to irradiate;
