Abstract

A plasticizing device that plasticizes at least a part of a material to generate a plasticized material, the plasticizing device includes: a drive motor; a screw configured to rotate around a rotation axis by a drive force of the drive motor and having a groove forming surface in which a groove is formed; a speed reducer disposed between the drive motor and the screw and configured to transmit the drive force of the drive motor to the screw; a barrel having a facing surface facing the groove forming surface and having a through hole into which the plasticized material flows; a first heater configured to heat the material supplied between the screw and the barrel; a first cooling unit configured to cool the drive motor; and a heat insulating unit disposed between the first cooling unit and the speed reducer. At least a part of the heat insulating unit overlaps the first cooling unit when viewed along the rotation axis of the screw.
