摘要
An object of the present invention is to provide a hot end of a molding material for a three-dimensional molding device with high reliability in which clogging of the molding material is prevented. A hot end of a molding material for a three-dimensional modeling apparatus includes a supply unit having a supply port of a filamentous molding material, and a melting unit to which a heating member is attached and melts the molding material supplied from the supply unit. A discharge section having a discharge port for discharging the molding material melted in the melting section, and a passage communicating the supply port and the discharge port, wherein the molding material melted in the melting section in the passage Is provided with a ring-shaped backflow prevention member for preventing backflow from flowing toward the supply section side.
