Abstract:
A three-dimensional shaping apparatus includes a shaping table  31,  a squeegee  32,  a sintering device, a cutting device, transport pathways  4  through which metal powder and fumes that have been discharged to the outer side of a shaping tank  1  after cutting with the cutting device, and metal powder that has been discharged to the outer side of a chamber  2  surrounding the shaping tank  1  without forming part of the laminated layer, are transported to a sifter  5  located at the top of a powder tank  6,  and supply devices for inert gas that does not react with the metal powder at an inlet  40  of each transport pathway  4,  so as to suppress oxidation of metal powder in the transport pathway for collected metal powder and fumes, and also dust explosion due to sudden oxidation of the same.

Claim (Index 1):
A three-dimensional shaping apparatus comprising:\n a shaping table that is raised and lowered within a shaping tank, a squeegee that disperses metal powder by movement in a horizontal direction and forms a laminated layer from the metal powder, a sintering device for irradiating the laminated layer of metal powder with one of a laser beam and electron beam, a cutting device for cutting a product formed by irradiated laminated layers, by rotation of a tool, transport pathways through which metal powder and fumes that have been discharged to an outer side of the shaping tank after cutting with the cutting device, and metal powder that has been discharged to an outer side of a chamber surrounding the shaping tank without forming part of the laminated layer, are transported to a sifter located at the top of a powder tank, one of the following:\n a compressor for injecting inert gas that does not react with the metal powder at an inlet of each transport pathway, \n a suction device for sucking the inert gas at an end of each transport pathway, or \n both the compressor and the suction device.
