<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a three-dimensional article which enables efficient molding with plural light beams. <P>SOLUTION: A metal light forming machine 1 has a forming plate 3 on which a powder layer 21 of a metal powder 2 is laid, a forming table 31 holding the forming plate 3 and moving vertically, a powder layer forming section 4 forming the powder layer 21, an irradiation section 5 irradiating the powder layer 21 with two or more light beams, a camera 6 photographing the status of molding and a control section controlling the metal light molding machine 1. In the molding area of each powder layer 21, a molding area for molding is assigned preliminarily to each light beam L, and the irradiation section 5 is made to carry out scanning data sequences for individual molding areas at the same time, with each of the scanning data sequences carried out in order, so as to mold a three-dimensionally shaped molding through these parallel operations. Because a target powder layer can be irradiated with two or more light beams through parallel operations, a three-dimensionally shaped forming can be manufactured efficiently. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
