Abstract

See full text

A plasticizing device includes: a flat screw having a groove formation surface in which a spiral groove is formed and configured to rotate about a rotation axis by a motor; a barrel having a facing surface facing the groove formation surface in a direction of the rotation axis; a heater configured to heat the material supplied between the groove formation surface and the facing surface; and a screw case accommodating the flat screw and having a supply port through which the material is supplied to the groove. The flat screw includes a first side surface in which an introduction port for introducing the material from the supply port into the groove is partially formed, and a second side surface provided on a side farther away from the barrel than the first side surface. A first distance which is a shortest distance between the first side surface and the screw case is larger than a second distance which is a shortest distance between the second side surface and the screw case, and a recessed portion is formed in the second side surface.
