PLASTICIZED MATERIAL FEEDING DEVICE, AND THREE-DIMENSIONAL MODELING APPARATUS

To provide a plasticized material feeding device and a three-dimensional modeling apparatus capable of enhancing quality of a three-dimensional modeled object.SOLUTION: A plasticized material feeding device comprises: a nozzle that discharges a plasticized material toward a stage; a first channel through which a first plasticized material flows; a second channel through which a second plasticized material flows; a third channel through which the plasticized material flows; a flow rate regulation mechanism provided at a confluence of the first channel, the second channel, and the third channel to regulate a discharge amount of the plasticized material from the nozzle; and a controller for controlling the flow rate regulation mechanism. The flow rate regulation mechanism has a butterfly valve 620 formed by processing a part of a drive shaft 610 disposed along a direction that crosses an extending direction of the third channel; and a drive motor 631 for rotating the butterfly valve 620 by rotating the drive shaft 610.SELECTED DRAWING: Figure 1 【課題】三次元造形物の品質を高めることが可能な可塑化材料供給装置、及び三次元造形装置を提供する。【解決手段】可塑化材料をステージに向けて吐出するノズルと、第１可塑化材料が流れる第１流路と、第２可塑化材料が流れる第２流路と、可塑化材料が流れる第３流路と、第１流路と第２流路と第３流路との合流点に設けられ、ノズルからの可塑化材料の吐出量を調節する流量調節機構と、流量調節機構を制御する制御部と、を備え、流量調節機構は、第３流路が延びる方向と交差する方向に沿って配置された駆動軸６１０の一部が加工されて形成されたバタフライバルブ６２０と、駆動軸６１０を回転させることによってバタフライバルブ６２０を回転させる駆動モーター６３１と、を有する。【選択図】図１
