Abstract
A method for manufacturing a three-dimensional shaped object, comprising: (i) forming a powder layer on a base plate by a sliding movement of a squeegee blade, followed by forming a solidified layer by irradiating a predetermined portion of the powder layer with a light beam, thereby allowing sintering of the powder of the predetermined portion or melting and subsequent solidification thereof; and (ii) forming another solidified layer by newly forming a powder layer on the resulting solidified layer, and then irradiating another predetermined portion of the new powder layer with the light beam, steps (i) and (ii) being repeatedly performed,
