Abstract
A lamination molding apparatusincludes a powder layer forming apparatus, a recoating head, a servo motor, a laser irradiating device, a numerical control apparatus, a laser control apparatusand a computer aided manufacturing (CAM) system. The blademoves in the horizontal axis direction so as to form the powder layer on a predetermined molding region. The laser control apparatuscontrols the laser irradiating deviceand calculates an irradiation range of a laser beam for every powder layer. The numerical control apparatusobtains data of the irradiation range from the laser irradiating deviceand outputs a move command such that the blademoves at a feed speed faster than a pre-set feed speed adapted for recoating, in the molding region outside of the irradiation range.
