Abstract
In a method for producing a three-dimensionally shaped object, (i) a solidified layer is formed by irradiating a light beam on a specified portion of a powder layer to sinter or melt the specified portion. Further, (ii) another solidified layer is formed by placing a new powder layer on the solidified layer obtained in step (i), and irradiating the light beam on a specified portion of the new powder layer to sinter or melt the specified portion of the new powder layer. The steps (i) and (ii) are repeated to produce a three-dimensionally shaped object. In the method, a gas is supplied to a mirror used in scanning the light beam.
