1. A method of fabricating a three-dimensional part comprising a metallic material, the method comprising:
(a) providing a wire comprising arc-melted metallic material, wherein the wire is produced by a process comprising (i) in a processing ambient comprising a vacuum or one or more inert gases, arc-melting a feed electrode comprising the metallic material to thereby form a billet, and (ii) mechanically deforming the billet into wire having a diameter less than a diameter of the billet;
(b) translating a tip of the wire relative to a platform;
(c) 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
(d) repeating steps (b) and (c) one or more times to produce the three-dimensional part,
wherein the three-dimensional part comprises the metallic material.
