A hybrid additive manufacturing method comprises building an additive structure on a pre-sintered preform base, wherein building the additive structure comprises iteratively fusing together a plurality of layers of additive material with at least a first layer of additive material joined to the pre-sintered preform base, and wherein the pre-sintered preform base comprises an initial shape. The hybrid additive manufacturing method further comprises modifying the initial shape of the pre-sintered preform base comprising the additive structure into a modified shape comprising the additive structure, and, joining the pre-sintered preform base in its modified shape to a component.
