Title:
MANUFACTURING DEVICE AND MANUFACTURING METHOD FOR METAL ADDITIVELY MANUFACTURED OBJECT
Document Type and Number:
WIPO Patent Application WO/2023/067701
Kind Code:
A1
Abstract:
The present invention realizes a manufacturing device and a manufacturing method for a metal additively manufactured object in which oxidation does not occur even when exposed to the atmosphere. A manufacturing device (100) for a metal additively manufactured object supplies a material for the metal additively manufactured object to a shaping region (23), performs irradiation using a heat source which melts the supplied material, blows a shielding gas into the shaping region (23), and measures the temperature at a measurement point in the shaping region (23). If the temperature at the measurement point during shaping reaches a temperature which was set on the basis of the oxidation temperature of the material, a control device (1) carries out control for stopping output or reducing output from the heat source and/or reducing the traveling speed or stopping the travel of the heat source which travels in the shaping region (23).
