Abstract
A 3D modeling device that forms a 3D object includes: a stage; a nozzle through which a fused material is ejected; a build plate disposed on the stage, the build plate receiving the fused material ejected through the nozzle to build the 3D object on the build plate; and a plasticizing member configured to plasticize a thermoplastic material to form the fused material. The plasticizing member includes: a flat screw having a grooved surface in which a groove is provided, the groove extending in a helical shape; a screw-facing piece having a communication path and a screw-facing surface facing the grooved surface; and a drive motor configured to rotate the flat screw. The groove continuously helically extends toward a material inlet from which the thermoplastic material in solid form is supplied, and the material inlet is provided on a side face of the flat screw.
