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 7):
The three-dimensional shaping apparatus according to  claim 6 , wherein the outlet for inert gas is at a top of the shaping tank and further comprising an outlet for oxygen at a bottom of the shaping tank.
