1. A method of making an additively manufactured single-crystal metallic component, said method comprising:
(a) providing a metal-containing feedstock comprising a first metal or metal alloy, wherein said metal-containing feedstock is in the form of a solid powder, a solid wire, or a combination thereof;
(b) providing a build plate comprising a build region consisting of a seed single crystal of a second metal or metal alloy;
(c) adding a first amount of said metal-containing feedstock to said build plate and then exposing said first amount of said metal-containing feedstock to an energy source for melting said first amount of said metal-containing feedstock, thereby generating a first melt layer disposed on said build region; and
(d) solidifying said first melt layer, thereby generating a first solid layer, disposed on said build region, of an additively manufactured metal component, wherein said first solid layer is a single crystal of said first metal or metal alloy.
