Title:
THREE-DIMENSIONAL MODELING DEVICE AND THREE-DIMENSIONAL MODELING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/244416
Kind Code:
A1
Abstract:
This three-dimensional modeling device (100) is provided with a powder supply device (10) which supplies a powder (90) by dropping onto a surface (81) of a workpiece (80) that, for example, exhibits a curve as the modeling object. Further, the three-dimensional modeling device (100) is provided with a laser beam irradiating device (20) which, as an energy beam, irradiates a laser beam (25) onto a layer of the deposited powder (90) supplied by the powder supply device (10). In this way, a three-dimensional modeling device and three-dimensional modeling method are provided which enable modeling a beam structure on a surface of the modeling object that exhibits a curve.
