Abstract
A plasticization device includes: a rotor rotated by a drive motor and having a groove forming surface in which a first groove portion is formed along a rotation direction; a rotor case configured to accommodate the rotor; a barrel facing the groove forming surface and having a through hole; a first heating unit configured to heat the rotor or the barrel; and a cooling mechanism configured to cool a side surface of the rotor. In the plasticization device, a material supplied between the first groove portion and the barrel is plasticized by rotation of the rotor and heating by the first heating unit to flow out from the through hole, and the side surface of the rotor has a material guiding port configured to guide the material to the first groove portion, and a second groove portion configured to feed the material supplied between the rotor and the rotor case to the material guiding port.
