3D 3D Nozzle for 3D printer based on glass fused deposition and 3D printer based on glass fused deposition using the nozzle

摘要

The present invention, a filament guide made of a glass filament, a housing body surrounding and receiving the filament guide, and a nozzle connected to a lower portion of the filament guide to temporarily store molten filament or discharge a target amount A tip and a housing coupling portion coupled to the lower portion of the housing body while providing a space for receiving the nozzle tip so that the filament guide and the nozzle tip are fixed so as not to be separated and detachable from the housing body, and the filament A heating element for heating the filament introduced into the guide, and a heat insulating material provided between the heating element and the housing body to prevent the heating element and the housing body from being short-circuited and to prevent internal heat from escaping to the outside. For glass melt deposition 3D printers Bla and to a glass melting metal evaporated 3D printer using the same. According to the present invention, it is possible to use a filament made of glass as a raw material for the production of a three-dimensional output, and it is easy to exchange the filament guide and the nozzle tip as consumables.
