Document Type and Number:
WIPO Patent Application WO/2017/163433
Kind Code:
A1
Abstract:
The present invention controls temperature increases in a workpiece (layering base material) to suppress the occurrence of thermal distortions. Provided is a 3D additive manufacturing device that is equipped with the following configuration. The 3D additive manufacturing device is equipped with a material injecting unit for injecting material for a 3D additively manufactured object upon a workpiece whereon the 3D additively manufactured object is manufactured. The 3D additive manufacturing device is also equipped with a light beam irradiating unit for irradiating the injected material with light beams. The 3D additive manufacturing device is further equipped with a jig to which the workpiece is removably attached. In addition, the jig is provided with a channel through which a cooling medium for cooling the workpiece is supplied.
