Abstract
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.
