3D WIRE ARC DIRECTED ENERGY DEPOSITION 3D PRINTING APPARATUS FOR FLATTENING OUTER SURFACE

摘要

In one embodiment of the present invention, in order to produce a printing object to be printed, a printing nozzle that generates an arc as the filler material is dropped, and the printing nozzle are disposed adjacent to the printing nozzle, the filler metal and the printing filler material from the printing nozzle It provides a 3D printing apparatus capable of surface planarization comprising a planarization module for flattening the surface of the printing stack by cooling a portion of the printing stack formed by melting.
