Method and apparatus for in-situ thermal management and heat treatment of additively manufacturing components

A method of additively manufacturing a metallic component, the method comprising:

• a. depositing, using a deposition head operatively controlled by a central processing unit, filler material on a substrate forming a deposition layer;
• b. measuring, via a temperature sensor controlled by the central processing unit, a temperature of a heat affected zone corresponding to the deposition layer;
• c. solution heat treating the deposition layer subsequent to the depositing, wherein said solution heat treating comprises:
• heating the deposition layer using a heat source to a solution temperature so as to achieve solution heat treatment, and using a cooling source, controlling a cooling rate of the deposition layer to at or above the critical cooling rate of the filler material until a target temperature is reached;
• and
• d. repeating steps (a)-(c) for multiple deposition layers as the metallic component is being formed;
• wherein the deposition head, the heat source, and the cooling source are connected so that, when the deposition head, the heat source, and the cooling source move, the deposition head, the heat source, and the cooling source move together, in unison, in relation to the substrate on one side of the metallic component while performing steps (a)-(d).
