摘要：
A thin-walled metal part, and a method to fabricate such a part out of various alloys. A plurality of layers are formed, each of the layers being formed on a polymer template or on a previously formed layer. A homogenizing heat treatment is used to cause chemical elements in the layers to interdiffuse, to form a single continuous layer with a substantially uniform alloy composition.
