Claim 0:
1. A three-dimensional shaping device comprising:
a shaping vessel that has an outer peripheral wall and a shaping stand, the shaping stand configuring a bottom portion of the shaping vessel;
a rotation mechanism that rotates the shaping stand and the outer peripheral wall at a same angular speed;
a raising and lowering device that raises and lowers the shaping stand inside the outer peripheral wall;
a chute that is disposed above the shaping stand and that delivers powder of a shaping material to the shaping vessel;
a leveling plate that is provided on a downstream side in a rotating direction of the chute, and that flatly levels the powder that has been delivered from the chute; and
a blocking wall that blocks a gap between an outer peripheral end of the chute and an outer peripheral end of the leveling plate,
wherein,
a lower end of the leveling plate is disposed at a closer position to the shaping stand than a lower end of the chute is, and
the blocking wall is positioned directly above an end portion on an inner peripheral side of the outer peripheral wall that rotates relative to the chute,
wherein the outer peripheral wall and the shaping stand are connected via a synchronous rotation mechanism that, while restricting relative movement in a circumferential direction of the outer peripheral wall and the shaping stand with respect to each other, enables relative movement of the outer peripheral wall and the shaping stand in an axial direction.
