Summary:PROBLEM TO BE SOLVED: To easily and correctly perform correction allowing a machining coordinate system and a light beam coordinate system to coincide. SOLUTION: The operation of applying the prescribed parts of the layer of a powder material with light beams and sintering the powder in the parts to form a sintered layer is repeated, and further, after the formation of the sintered layer, a stage where the surface part and required parts of a light beam fabrication produced till then are machined away is inserted in the process of a plurality of production stages for the sintered layer, thus a light beam fabrication product is produced. In this case, the application of marks 60 by a machining means and marks 61 by a light beam irradiating means is performed to predetermined points on a calibration board 6 set in the irradiating face of the light beams, and a controller performing the control of the machining means and the light beam irradiating means corrects the machining positions or the light beam irradiating positions based on the quantity of the position deviation in both the kinds of marks obtained from a position measuring means for the marks 60 and 61. By actually performing the machining and light beam irradiation, the correction of aligning the irradiating positions with the positions of knife edges for machining as an end effector as a standard is performed.
