Abstract
A lamination molding apparatus with a molding table, including: a galvanometer scanner configured to irradiate a small irradiation region on the molding table with a laser beam; an inert gas supplying nozzle having an inert gas supplying opening for supplying an inert gas; a fume suction duct having a fume suction opening for suctioning the inert gas containing fumes generated with irradiation of the laser beam; an integration unit integrally including the galvanometer scanner, the inert gas supplying nozzle and the fume suction duct; and a moving device configured to move the integration unit so the galvanometer scanner scans and irradiates the laser beam on a large irradiation region larger than the small irradiation region on the molding table; wherein the inert gas supplying opening and the fume suction opening are opposed to each other so an irradiation path of the laser beam is placed therebetween.
