Kind Code:
A1
Abstract:
The objective of the present invention is to provide: a system for manufacturing an additive manufactured object that can enhance the preciseness of defect evaluation during additive manufacturing and the quality of the additive manufactured object; and a method for manufacturing an additive manufactured object. A system (1a) for manufacturing an additive manufactured object according to the present invention is characterized by including an additive manufacturing device (10a) that performs an additive manufacturing process in which a powder layer formation step for forming a powder layer through the supplying of powder and a solidified layer formation step for forming a solidified layer by supplying heat to the powder layer from a heat source and fusing and solidifying the powder are repeated, an inspection device (20) that has cameras (6, 7) for photographing the powder layer or the solidified layer, and a control device (30) that performs control of the additive manufacturing device (10a) and the inspection device (20), and in that the cameras (6, 7) are capable of photographing the powder layer each time the powder layer formation step is repeated or the solidified layer each time the solidified layer formation step is repeated, and the control device (30) selects the photographing conditions of the cameras (6, 7) in accordance with the conditions of the additive manufacturing process.
