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 selective laser sintering method capable of reducing the bulge of the peripheral portion corresponding to the periphery of the three-dimensional shaped object. The manufacturing method according to an embodiment of the present invention includes 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 sintering the powder in the predetermined portion or a melting and subsequently solidifying the powder; and (ii) forming another solidified layer by newly forming a powder layer on the formed solidified layer, followed by irradiation of a predetermined portion of the newly formed powder layer with the light beam, wherein a scanning of the light irradiation is divided into light beam-scannings “A” and “B”.
