Abstract: There is provided a method for manufacturing a three-dimensional shaped object. The method of the present invention comprises the repeated steps of: (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 thereof; and (ii) forming another solidified layer by newly forming a powder layer on the resulting solidified layer, followed by the irradiation of a predetermined portion of the powder layer with the light beam; wherein only the surface portion of the solidified layer, to which a force is applied when the three-dimensional shaped object is used, is subjected to a machining process.

Abstract: An object of the present invention is to easily eliminate fumes inside a chamber, so as to improve a positional accuracy of irradiation with a light beam and a machining accuracy in a method for manufacturing a three-dimensional shaped object. A stacked-layers forming device 1 includes a powder layer forming unit 3, a light beam irradiating unit 4, a base 22 which is fixed and on which a powder layer 32 is formed, a lifting/lowering frame 34 which surrounds the circumference of the base 22 and is freely capable of being lifted and lowered, a cover frame 36 which has a window 36a allowing transmission of light beam in its top surface, and whose bottom surface is opened, and which is disposed on the lifting/lowering frame 34 to form a chamber C, and a gas tank 71 for supplying an ambient gas. The lifting/lowering frame 34 is lowered to reduce the volume of the chamber C, so as to discharge fumes generated inside the cover frame 36, which performs replacement with the ambient gas. Since the volume of the chamber C is reduced, it is possible to easily eliminate the fumes, which makes it possible to improve the positional accuracy of irradiation with the light beam L, and the machining accuracy.

Abstract: A metal powder for use in a metal laser-sintering wherein a three-dimensional shaped object is produced by irradiating a powder layer of the metal powder with a light beam to form a sintered layer and thereby laminating the sintered layers. The metal powder of the present invention is characterized in that it comprises an iron-based powder and at least one kind of powder selected from the group consisting of a nickel powder, a nickel-based alloy powder, a copper powder, a copper-based alloy powder and a graphite powder; and the iron-based powder has been annealed. In such metal powder, the iron-based powder is in a softened state due to the annealing treatment thereof. Accordingly, the use of the metal powder in a metal laser-sintering process makes it possible to reduce a machining resistance attributable to the residual metal powder adherent to the surface of the shaped object, which leads to an achievement of an extended lifetime of a machining tool.
