Abstract: There is provided a more efficient method for manufacturing a three-dimensional shaped object. The method of the present invention comprises a successive formation of a plurality of solidified layers through a light beam irradiation, wherein the solidified layers are provided by a hybrid of combined systems of an after irradiation system and a simultaneous irradiation system, the after irradiation system being such that the light beam irradiation is performed after a formation of a powder layer, the simultaneous irradiation system being such that the light beam irradiation is performed while a raw material is supplied.

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, including: (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. The plurality of the solidified portions of the powder layers overlap each other, and after a formation of a first solidified portion, at least both main edge regions of the first solidified portion are irradiated with the light beam.
