Abstract

The three-dimensional shaping device () is provided with a powder supply device () to supply powder () by dropping the powder toward a surface () of a workpiece () as a shaping object, the surface, for example, being a curved surface. Further, the three-dimensional shaping device () is provided with a laser light irradiation device () to irradiate a layer of the powder () supplied and deposited by the powder supply device () with a laser light () as an energy beam. In this way, a three-dimensional shaping device and a three-dimensional shaping method, which are capable of shaping a beam structure on a curved surface of a shaping object, are provided.
