Abstract:
A plasticizing device (90) for a three-dimensional shaping apparatus includes a drive motor (32), a rotor (40) that is rotated by the drive motor and has a groove formed face (48) with a groove (42) formed therein, a barrel (50) that is opposed to the groove formed face and has a communication hole (56), a heating portion (70) that heats a material in a pellet form supplied between the groove and the barrel, and a control unit (500) that controls the drive motor and the heating portion so as to plasticize the material supplied between the groove and the barrel and cause the material to flow out from the communication hole. The heating portion has a first (71) and a second (72) heating portion disposed closer to the communication hole than the first heating portion, and the barrel has a first region (RG1) and a second region (RG2) that is closer to the communication hole than the first region. The control unit individually controls the first and second heating portions so that a temperature of the second region is higher than that of the first region.
