Abstract: A method for forming a secondary component from an original component having an original shape includes separating the original component into a parent component and a replaced portion, and forming a replacement coupon using an additive manufacturing system. The replacement coupon is shaped to substantially match the original shape of the replaced portion. The method further includes coupling the replacement coupon to the parent component to form the secondary component. The method also includes at least one of (i) removing the replacement coupon from a build plate of the additive manufacturing system prior to application of any heat treatment to the as-built replacement coupon, wherein the replacement coupon maintains a near-net original shape of the replaced portion after removal, and (ii) entering the secondary component into normal duty with no hot isostatic press treatment of the replacement coupon having been performed.
