Title:
3D PRINTER FOR METAL ALLOY FILAMENT
Document Type and Number:
WIPO Patent Application WO/2017/014457
Kind Code:
A1
Abstract:
The present invention relates to a 3D printer using a metal alloy filament, wherein the 3D printer introduces a metal alloy filament (650) through a nozzle (610) formed inside an induction heating coil (620), melts and extrudes the filament, and laminates the filament three-dimensionally inside a chamber (500) heated to a similar temperature. The present invention forcibly introduces a metal alloy filament in a nozzle, heated by an induction heating coil which circularly encloses the exterior of the nozzle and forms a cooling passage therein, by means of a transfer gear connected to a transfer motor. A 3D printer for a metal alloy filament is provided in which, in order to prevent the oxidation of a metal alloy laminate (520), an inert gas is introduced, the outside and heat and air are blocked, and a metal alloy filament (650) that is melted in a nozzle and extruded is laminated one layer at a time on a floor plate (510) installed inside a heated chamber (500) and moving three-dimensionally with respect to the nozzle, in order to firmly attach the filament having little deformation.
