Abstract
The manufacturing device manufactures a laminate shaped object by supplying material powder to a molding chamber to form a powder layer and irradiating a surface of the powder layer with a beam to sinter the powder layer. The molding chamber has a molding space where the material powder is irradiated with the beam and the laminate shaped object is formed, and a non-molding space which is outside the molding space and in which the laminate shaped object is not formed. An elastic member is disposed in the non-molding space, and the elastic member extends or contracts to change volume along with change of a relative position of the table in a vertical direction.
