In accordance with an exemplary embodiment, a method for repairing a damaged metallic component using additive manufacturing techniques includes separating a damaged portion of the damaged metallic component from an undamaged portion of the damaged metallic component, measuring the undamaged portion to determine the dimensions of the removed damaged portion, fabricating a replacement portion using additive manufacturing techniques in accordance with the determined dimensions of the removed damaged portion, and joining the replacement portion with the undamaged portion of the damaged metallic component to form a repaired metallic component.
