PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a three-dimensional laminated molding, capable of reducing the supply of powder material to a non-molding space through change of the space capacity in a molding tank.SOLUTION: An apparatus 1 for manufacturing a three-dimensional laminated molding using powder material includes a molding tank 10 having a peripheral wall 11 and a table 12 as bottom wall, with the relative positional relationship between the peripheral wall 11 and the table 12 in the height direction being changeable. While powder material is supplied to the molding tank 10 to form a powder layer 20 by lamination, the surface layer of the powder layer 20 is irradiated with a beam to solidify the irradiated portion. The molding tank 10 includes an expandable member 30 which allows the space in the molding tank 10 to be changed through expansion and contraction of the expandable member 30. |
