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.

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.
