A lamination molding apparatus 10 includes a powder layer forming apparatus 20, a recoating head 30, a servo motor 16, a laser irradiating device 40, a numerical control apparatus 52, a laser control apparatus 54 and a computer aided manufacturing (CAM) system 56. The blade 31 moves in the horizontal axis direction so as to form the powder layer on a predetermined molding region. The laser control apparatus 54 controls the laser irradiating device 40 and calculates an irradiation range of a laser beam for every powder layer. The numerical control apparatus 52 obtains data of the irradiation range from the laser irradiating device 40 and outputs a move command such that the blade 31 moves at a feed speed faster than a pre-set feed speed adapted for recoating, in the molding region outside of the irradiation range.
