DED ARC THREE-DIMENSIONAL ALLOY METAL POWDER PRINTING METHOD AND APPARATUS USING ARC AND ALLOY METAL POWDER CORE WIRE

WIPO Patent Application WO/2017/073947

A1

Disclosed are a DED arc three-dimensional alloy metal powder printing method using an arc and an alloy metal powder core wire, and an apparatus therefor. A DED arc three-dimensional alloy metal powder printing method, according to an embodiment of the present invention, comprises the steps of: (a) connecting a three-dimensional printing part mold with a first electrode via a ground line, contacting a second electrode, in which an electrode contact tip is tapped on a peripheral surface of an alloy metal powder core wire, with a part of the surface of the printing part of the mold, and then generating an arc by a potential difference between the first electrode and the second electrode to melt the front end of the alloy metal powder core wire and the surface of the printing part at the same time; (b) forming a monolayer by mixing and coagulating the melt of the alloy metal powder core wire and the melt of the surface of the printing part; and (c) stacking the monolayer by continuously performing a monolayer overlay.
