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”.
