1. A three-dimensional modeling apparatus that produces a three-dimensional object, the three-dimensional modeling apparatus comprising:
a nozzle having an ejection port that ejects a plasticized material;
a plasticization unit configured to plasticize a material containing thermoplastic resin to generate the plasticized material;
an open/close unit that is disposed in a flow path through which the plasticized material flow and controls an outflow of the plasticized material from the ejection port by opening and closing the flow path;
a suction unit that is disposed in the flow path downstream of the open/close unit and suction the plasticized material in the flow path; and
a controller configured to control the plasticization unit, the open/close unit, and the suction unit,
wherein when stopping the outflow of the plasticized material from the ejection port, the controller drives the open/close unit such that the flow path is closed, and then drives the suction unit such that the plasticized material in the flow path is sucked.
