Title: FABRICATON OF METALLIC PARTS BY ADDITIVE MANUFACTURING
Abstract:
In various embodiment, the present invention relates to method of fabricating a three-dimensional part by a process comprising the steps of: providing a wire comprising arc-melted refractory metallic material; translating a tip of the wire relative to a platform; while the tip of the wire is being translated, melting the tip of the wire with an energy source to form a molten bead, whereby the bead cools to form at least a portion of a layer of a three-dimensional part; and repeating steps (b) and (c) one or more times to produce the three dimensional part.
