Abstract
A lamination molding method, which repeats a material layer forming step of forming a material layer and a solidifying step of irradiating an irradiation region of the material layer with laser beams scanned by n scanners to form a solidified layer, includes: a first dividing step and an irradiation order deciding step. In the first dividing step, the irradiation region is divided to 2n-1 or more divided regions by a plurality of first dividing lines in a manner that irradiation time of each of the divided regions to which the laser beams are simultaneously irradiated becomes equal. In the irradiation order deciding step, an irradiation order of the divided regions in the solidifying step is decided in a manner that the laser beams are simultaneously irradiated to the divided regions that are not adjacent, and the laser beams are not simultaneously irradiated to the divided regions that are adjacent.
