<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a three-dimensional article by which the position of a light beam irradiation can be easily corrected. <P>SOLUTION: A metal optical molding processing machine (1) comprises a powder layer forming section (2), an irradiating section (3) for irradiation with a light beam (L), a correction target (4) to which a correction mark becoming the reference for correcting the light beam irradiating position is put, and an imaging camera (5) for imaging the position of the correction mark. The correction target (4) is made of such a material as dissolving through irradiation with the light beam (L) and a through-hole is made. The correction target (4) is mounted on a molding plate (23) and irradiated with the light beam (L), thus putting a correction mark (7) while penetrating the correction target (4). Thereafter, the correction mark (7) is imaged by means of the camera (5) and the position of the correction mark (7) is measured in order to correct the irradiating position. Since the correction mark (7) is formed while penetrating, contrast becomes clear, the position of the correction mark (7) is measured easily, and the irradiating position with the light beam (L) can be corrected easily. <P>COPYRIGHT: (C)2009,JPO&INPIT |
