Abstract: There is provided a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming by an irradiation with a light beam in order to provide a selective laser sintering method capable of reducing a warp of the three-dimensional shaped object, the warp being due to a stress around an upper surface of the three-dimensional shaped object. Especially, in the present invention, a part of a region for the formation of the solidified layer is not irradiated with the light beam to form a non-irradiated portion, thereby providing at least one slit-groove at an upper surface of the three-dimensional shaped object, the slit-groove being for reducing a stress of the three-dimensional shaped object.

Abstract: Apparatus for manufacturing a three-dimensional shaped object comprises a chamber, a transmission window, a blow-out port and a cover member, wherein a solidified layer is formed by irradiation of a predetermined portion of a material layer with a light beam, thereby allowing a sintering of the material in the predetermined portion or a melting and subsequent solidification of the material, the material layer being provided within the chamber. The transmission window is provided in the chamber, allowing the light beam to be transmitted therethrough. The blow-out port is located around the transmission window, and serves for blowing out an inert gas toward an interior of the chamber. The cover member, which is positioned below the blow-out port and also serves for surrounding the blow-out port, has an annular form. A gap through which the inert gas passes is provided between the cover member and the transmission window.

Abstract: A selective laser sintering method reduces a warping deformation of a three-dimensional shaped object, the warping deformation being due to the scanning of a light beam. The manufacturing method is a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming, wherein a scanning of the light irradiation is divided into light beam-scannings “A” and “B”, the light beam-scanning “A” being for the light irradiation of a peripheral portion corresponding to a periphery of the three-dimensional shaped object, and the light beam-scanning “B” being for the light irradiation of an internal portion corresponding to a region of the three-dimensional shaped object, the region being located inside the periphery. In particular, the peripheral portion is subjected to a discontinuous light beam-irradiation in the light beam-scanning “A” such that an irradiation path of the light beam is divided into a plurality of sub-irradiation paths.
