1. A three-dimensional shaping device comprising:
a material dispensing device configured to dispense a material for shaping from a dispensing unit; and
a stage configured to receive the material for shaping dispensed from the dispensing unit, wherein the material dispensing device comprises
a material storage unit configured to store a material therein and having an outlet portion at a lower portion thereof;
a dispensing unit configured to dispense the material supplied from the outlet portion to an outside with at least a part of the material being plasticized;
a remaining amount detection unit configured to detect a remaining amount of the material stored in the material storage unit from above the material storage unit;
a first movement unit configured to move the material storage unit and the dispensing unit in a first direction perpendicular to the stage;
a second movement unit configured to individually move the material storage unit in the first direction;
a third movement unit configured to individually move the dispensing unit in the first direction; and
a control unit configured to:
control movement operations of the first movement unit, the second movement unit, and the third movement unit, and
during shaping, the control unit causes the third movement unit to move the dispensing unit, and causes a dispensing port of a nozzle included in the dispensing unit to be closer to the stage than during a period other than during the shaping.
