Claim:
1. A lamination molding apparatus, comprising: a blade, forming a powder layer at a predetermined molding region by moving in a horizontal axis direction for each sliced layer sliced from an entire molding space with a predetermined thickness, wherein the entire molding space includes a desired molding object; a laser irradiating device irradiating a laser beam at a predetermined irradiation region in the molding region; a laser control apparatus controlling the laser irradiating device and calculating an irradiation range of the laser beam in the horizontal axis direction for the each sliced layers; and a numerical control apparatus obtaining data of the irradiation range from the laser control apparatus and outputting a move command, so as to move the blade at a feed speed faster than a preset feed speed adapted for recoating, at a molding range outside the irradiation range.
