摘要： The lamination molding apparatus includes an irradiator, a processing device, a cooling device, and an inert gas supply source. The irradiator irradiates a laser beam or an electron beam to a material layer to form a solidified layer. The processing device includes a processing head for holding a tool, and a processing head driver for moving the processing head in at least a horizontal direction. The cooling device is arranged in the processing head and cools a solidified body formed by laminating the solidified layers to a cooling temperature. The cooling device includes a cold gas discharger having a cold gas discharge port for discharging a cold gas being an inert gas having a temperature equal to or lower than the cooling temperature, and discharging the cold gas toward the solidified body. The inert gas supply source supplies the inert gas to the cold gas discharger.

摘要： Provided is a laminate molding apparatus including a chamber, a laser irradiation device, an inert gas supply device, a fume collector, and an evacuate device. The evacuate device includes an intake port, an evacuate amount adjusting portion, a controller, and an evacuate port. The intake port is connected to any part of the laminate molding apparatus through which the inert gas flows, and takes in the inert gas. The evacuate amount adjusting portion adjusts an evacuate amount of the inert gas. The controller controls the evacuate amount adjusting portion to evacuate the inert gas such that an atmospheric pressure in the chamber and an external atmospheric pressure become uniform within a range in which leakage of the inert gas from the chamber is suppressed. The evacuate port evacuates the inert gas from which fumes have been removed to the outside of the laminate molding apparatus.
