<P>PROBLEM TO BE SOLVED: To manufacture a three-dimensionally shaped article in a short time. <P>SOLUTION: A three-dimensionally shaped article is manufactured from a powder by laminating layers one by one, that is, by repeating the steps of forming an inorganic or organic powder layer 20 on a sintering table 3, then sintering the specified part of the layer 20 by laser beam exposure and sintering the specified part of a new powder layer formed on the existing layer 20 by laser beam exposure to obtain the sintered part 21 integrated with the sintered part 21 of the lower layer. In this method, a base 1 which becomes a lower structural material of the three-dimensionally shaped material to be manufactured, is set on the sintering table 3, then the alignment of the base 1 and a laser beam irradiation starting position is performed after applying a specified processing to the surface of the base 1, and the steps of forming the powder layer covering the base 1 and sintering the specified part of the powder layer by the laser beam, are repeated. It is possible to omit the repetition of the steps of forming the powder layer and sintering its specified part under laser beam exposure by the thickness portion of the base 1. <P>COPYRIGHT: (C)2004,JPO |
