Title:
EJECTION HEAD OF MOLDING MATERIAL FOR 3D MODELING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/155611
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve downsizing, weight reduction, energy saving, and service life extension and also to improve the freedom of selection of a modeling material by enabling high-temperature operation. For this purpose, a discharge head is made in which a supply unit (10) having a supply port (11) for a filament, a melting unit (30) for melting the supplied filament, a discharge unit (40) having a discharge port (41) for discharging the melted filament and a heat insulation portion (20) located between the supply unit (10) and the melting unit (30) are molded integrally. As a result, the conduction of heat of the melting unit to the supply unit can be effectively suppressed even when the melting unit is heated to a high temperature, the temperature of the supply unit can be kept at an appropriate level, and the heat of heating can be efficiently used in the melting unit.
