Abstract
An ion fusion formation method is used to manufacture a component from successive layers of feedstock material. A plasma stream is created by energizing a flowing gas using an arc electrode, the arc electrode having a variable magnitude current supplied thereto. The plasma stream is directed to a predetermined targeted region, and the feedstock material is introduced into the plasma stream to produce a pool of molten feedstock in the predetermined targeted region, the molten feedstock being produced at a temperature determined in part by parameters of the variable magnitude current. Prior to introducing the feedstock material into the plasma stream, optimal molten feedstock parameters may be determined for producing the layers of feedstock material. Feeding parameters by which the feedstock material will be introduced into the plasma stream are then adjusted in view of the determined optimal molten feedstock parameters.
