An internal defect detection system for a three-dimensional additive manufacturing device which performs additive molding by emitting a laser beam to a powder bed is provided. This system specifies a candidate position of an internal defect on the basis of a change amount of a local temperature measured in an irradiated part of a powder bed irradiated by a laser beam. The system calculates a cooling speed at the candidate position on the basis of a temperature distribution and determines whether an internal defect exists on the basis of the cooling speed.

A method of manufacturing a fabricated object includes forming the fabricated object by laminating metal powder, the fabricated object including an opening portion that communicates with a hollow internal space, mounting a plug in the opening portion, and welding the plug mounted in the opening portion to the fabricated object.

Method of manufacturing fabricated object

A three-dimensional additive manufacturing device is configured to emit a beam to a powder bed formed by laying a powder on a base plate to harden the powder bed selectively. A sensor is configured to detect the shape or the temperature of a surface of the powder bed or a modeling surface. A defect in laying of the powder or a defect in emission of the beam is corrected based on the detection result, before completion of forming of the next layer.
