Abstract

There is provided a method for manufacturing a three-dimensional shaped object, comprising the steps of: (i) forming a solidified layer by irradiating a predetermined portion of a 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, the steps (i) and (ii) being repeatedly performed, wherein the three-dimensional shaped object is manufactured such that it has three different solidified portions of high-density, intermediate-density and low-density solidified portions in at least a part of the object, and wherein the intermediate-density solidified portion is formed to be located in a part of a surface of the three-dimensional shaped object.
