Discharge head for modeling material for 3D modeling apparatus and 3D modeling apparatus

摘要

In addition to miniaturization, weight reduction, energy saving, and long life, it is also possible to increase the degree of freedom in selecting molding materials by enabling high-temperature operation. Therefore, a supply unit (10) having a filament supply port (11), a melting unit (30) for melting the supplied filament, a discharge unit (40) having a discharge port (41) for discharging the melted filament, And by making the heat insulation part (20) between the supply part (10) and the melting part (30) into an integrally formed discharge head, the heat of the melting part is supplied even if the melting part is heated to a high temperature. It is possible to effectively suppress the conduction to the heat source, maintain the temperature of the supply part at an appropriate temperature, and efficiently use the heated heat for the melting part.
