Abstract

To provide a plasticizing device capable of easily executing maintenance of a barrel. A plasticizing device includes: a drive motor; a flat screw having a groove forming surface in which a groove is formed, and rotating around a rotation axis of the drive motor; a barrel having a facing surface facing the groove forming surface and having a communication hole formed therein; and a heating unit configured to heat a material supplied between the flat screw and the barrel. The barrel has a separate structure including, when viewed from a direction orthogonal to the rotation axis, a first barrel having the facing surface, and a second barrel separated from the facing surface.
