Abstract: There is provided a manufacturing method of the three-dimensional shaped object, the method being capable of suitably reducing the local raised portion which can occur during the light beam irradiation under the condition of the divided sub-irradiation paths. The manufacturing method of the present invention is performed by repetition of a powder-layer forming and a solidified-layer forming, wherein an irradiation path of the light beam is divided into a plurality of sub-irradiation paths including a short sub-irradiation path with its length being shorter than a predetermined length and a long sub-irradiation path with its length being the predetermined length or longer, and wherein an irradiation mode of the light beam is changed depending on the lengths of the sub-irradiation paths.

Abstract: There is provided a manufacturing method of a three-dimensional shaped object, the method being capable of reducing a warp deformation of the three-dimensional shaped object. The manufacturing method according to an embodiment of the present invention produces a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming on a base plate, wherein the forming of at least one prior solidified layer is performed under a higher temperature condition than that for the forming of a subsequent solidified layer, the at least one prior solidified layer being formed prior to the subsequent solidified layer.

Abstract: There is provided a manufacturing method of a three-dimensional shaped object, the method being capable of reducing a warp deformation of the three-dimensional shaped object. The manufacturing method according to an embodiment of the present invention produces a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming by light beam irradiation, wherein as a platform for the three-dimensional shaped object, a plate laminate body comprising a dummy solidified layer and a base plate for the shaped object is used, and the dummy solidified layer is formed on one of principal surfaces of the base plate, whereas the three-dimensional shaped object is manufactured on the other of the principal surfaces of the base plate.

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.
