MANUFACTURING DEVICE FOR METAL OBJECT, MANUFACTURING METHOD FOR METAL OBJECT, AND METAL POWDER RECOVERY METHOD

摘要

The purpose of the present invention is to provide a manufacturing device and a manufacturing method with which it is possible to manufacture a metal object with superior mechanical properties and design for external appearance as well as a metal powder recovery method with which it is possible to easily reuse powder not affected by heat. Provided is a device (20) for manufacturing a metal object for manufacturing a metal object (X) by irradiating the surface layer of metal powder (M), which fills a fabrication tank (12) of a fabrication stage (10), with laser light (L) and fabricating and laminating layers of metal, said device being characterized by comprising a calculation unit (4) for calculating a second region which is a region surrounding a first region irradiated by the laser light (L) and an elimination mechanism (5) for eliminating metal powder included in the second region, which is calculated by the calculation mechanism, from the fabrication tank (12).
