Document Type and Number:

Japanese Patent JP7084224

Kind Code:

B2

Abstract:

The three-dimensional shaping device (100) is provided with a powder supply device (10) to supply powder (90) by dropping the powder toward a surface (81) of a workpiece (80) as a shaping object, the surface, for example, being a curved surface. Further, the three-dimensional shaping device (100) is provided with a laser light irradiation device (20) to irradiate a layer of the powder (90) supplied and deposited by the powder supply device (10) with a laser light (25) 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.
