Plasticizing Device, Injection Molding Device, And Three-Dimensional Shaping Device

Abstract: a plasticizing device includes: a screw that is rotated about a rotation axis; a barrel that is formed with a communication hole into which a plasticized material obtained by plasticizing a material flows; a heater configured to heat the material; and a screw case that is formed with a recessed portion, and is formed with a supply port for supplying the material to the groove. a length of the screw in a direction along the rotation axis is smaller than a length in a direction perpendicular to the rotation axis, an introduction port is formed in a part of a side surface of the screw, a length of the introduction port is larger than a length of the supply port in the direction along the rotation axis, and a distance between the side surface and an inner wall of the recessed portion varies in a rotation direction of the screw.
