1. A system (100) for additively manufacturing or repairing a superalloy component from a base material (10) comprising:
a laser metal deposition (LMD) system (200) comprising:
a laser energy source (202) operably configured to direct a laser energy towards the base material for forming a melt pool thereon and for laser processing additive materials deposited into the melt pool for forming a layer of the additive materials on the base material; and
a means for cooling (300) the base material during laser processing to a desired cooling temperature within a range of −100° C. to −150° C., the means for cooling including a vessel (302) containing a liquid medium (310) in which a portion of the base material is submerged, the liquid medium including one of liquid nitrogen, liquid argon and liquid helium, flowing the liquid medium through the vessel and placing the base material in a flow of the liquid medium,
wherein the melt pool or the layer of the additive materials are not in contact with the liquid medium (310) and is supported by the base material.
