Abstract
An apparatus for producing a laminated object, includes a powder layer forming unit for forming a powder layer of a powdery material, a material supply unit for feeding the powdery material to the powder layer forming unit; and a solidified layer forming unit for forming a solidified layer by irradiating a light beam on a specified portion of the powder layer and sintering or melting the specified portion of the powder layer. The apparatus is configured to produce an integrally laminated three-dimensional object by repeating formation of the powder layer and formation of the solidified layer. The material supply unit includes a cartridge unit charged with the powdery material, the cartridge unit being configured to allow the powdery material to drop downwards.
