US 2019/0160746 A1 · Molten Material Supplying Apparatus, Three-Dimensional Modeling Apparatus, And Method For Producing Composite Material

Abstract

A molten material supplying apparatus includes: a first introduction unit introducing fiber material; a melting unit melting a thermoplastic resin into a molten material; a first flow path in which the molten material and the fiber material are distributed; and a nozzle communicating with the first flow path to feed a composite of the molten material and the fiber material. The melting unit includes: a facing section in which a communication hole communicating with the first flow path is formed, the facing section having a heater, and a flat screw which has a groove at a position facing the facing section, the flat screw being rotated to melt the thermoplastic resin into the molten material and supply the molten material into the communication hole. The first introduction unit introduces the fiber material into at least one of the communication hole and the first flow path.
