Additive manufacturing (AM) is a rapidly developing technology that is finding application in a wide variety of engineering disciplines. While AM is finding applications in the aerospace industry for the fabrication of low volume components with complex internal features from a monolithic metal, the market could be extended by the ability to fabricate bi-metallic structures. By combining additive method with subtractive methods, it is possible to use various metals in the build. Limitations from the AM processing can be improved by hybridizing the manufacturing process. As the material is deposited, machining can be done on internal features before they are buried in the build. This study looks at the fabrication of an igniter for a liquid rocket engine which has a Cu alloy core with an Inconel 625 structural jacket. Properties of the additive manufactured material will be discussed along with characterization of the intermetallic region of the bi-metallic joint.
