1. A system for additively manufacturing and/or repairing a superalloy component via laser metal deposition utilizing a sintered wire, comprising:
a pressure vessel connected to a powder feed system for delivering at least two powders to a powder mixing zone of the pressure vessel;
a heating device contained within the pressure vessel, the heating device configured to heat a mixture of the at least two different powders mixed in the powder mixing zone so that liquid phase sintering occurs creating a sintered wire;
a laser wire welding system, comprising:
a laser energy source operably configured to direct a laser energy towards a base material for forming a melt pool thereon and for laser processing the sintered wire deposited into the melt pool for forming a layer of additive material on the base material, and
a welding head for receiving the sintered wire directly from the pressure vessel,
wherein the sintered wire is continuously fed from the pressure vessel to the laser wire welding system.
