    Abstract: A method for manufacturing a three-dimensional shaped object comprising an undercut portion by alternate repetition of a powder-layer forming and a solidified-layer forming, the repetition comprising: (i) forming a solidified layer by irradiating a predetermined portion of a powder layer with a light beam, thereby allowing a sintering of the powder in the predetermined portion or a melting and subsequent solidification of the powder; and (ii) forming another solidified layer by newly forming a powder layer on the formed solidified layer, followed by an irradiation of a predetermined portion of the newly formed powder layer with the light beam. Especially, in the manufacturing method according to an embodiment of the present invention, a modeling process for pre-identifying the undercut portion is performed prior to a performance of the method.

    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.
