METHOD FOR MANUFACTURING THREE-DIMENSIONALLY SHAPED MOLDING

摘要

In order to provide a method for manufacturing a three-dimensionally shaped molding, whereby it is possible to suppress the occurrence of a protrusion in a portion irradiated by a light beam and sintered or melt-solidified, the present invention provides a method for manufacturing a three-dimensionally shaped molding, the method having a step (i) for forming a powder layer and a step (ii) for irradiating a predetermined location of the powder layer with a light beam and forming a solidified layer from the powder layer, the steps (i) and (ii) being repeated, wherein the method for manufacturing a three-dimensionally shaped molding is characterized in that vibration is imparted to the portion irradiated with the light beam in the step (ii).
