Title:
THREE-DIMENSIONAL SHAPING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/238436
Kind Code:
A1
Abstract:
The present invention reduces the burden and increases the efficiency of work of recovering a powder material from a shaping tank and returning same to a supply tank. A three-dimensional shaping apparatus 100 includes: a shaping tank 20 in which a three-dimensional shaped object 92 is shaped; a shaping table 24; a supply tank 30 that supplies a powder material 90; and a first screen 80 that is disposed in the shaping tank 20 and extends more upward than an upper position of the shaping table 24. When the shaping table 24 rises after the end of shaping of the three-dimensional shaped object 92, the powder material 90 rises to a comparatively high position while a spill thereof is prevented by the first screen 80. A worker can easily return the powder material 90 to the supply tank 30 by pushing the powder material 90 in one direction of the horizontal direction. The foregoing eliminates the need of work of lifting a scoop or the like from inside the shaping tank 20.
