1. A system for additively manufacturing or repairing a superalloy component from a base material comprising:
an inoculation feed operably configured to direct inoculation materials onto the base material before or during laser processing;
a powder nozzle configured to deliver additive materials comprising a nickel based superalloy for laser processing after delivery;
a laser metal deposition system comprising a laser energy source operably configured to direct a laser beam towards the base material and the inoculation materials for forming a melt pool thereon and for laser processing the additive materials deposited into the melt pool for forming a layer on the base material of the additive materials and the inoculation materials, and the laser energy source further being operably configured to function as a laser deposition tool for depositing the additive materials via a feed line into the melt pool; and
a processor configured to oscillate the laser beam within the powder nozzle so that the laser beam is agitated in the melt pool prior to depositing the additive materials into the melt pool.
