Direct metal deposition (DMD) or free-form additive manufacturing (AM) are generally based on either a robotic arm or CNC platform and use either wire or a blown powder as the feed stock. An important advantage of these AM methods is their ability to print larger parts and use various metals to produce a bimetallic build. The abilities of both blown powder and wire-fed DMD processes to create bimetallic parts were investigated with specific interest in the interface formed between copper (Cu) based alloys and nickel (Ni) based superalloys. This study evaluated the interfaces between the two alloys for the different processes using optical microscopy, macrohardness, uniaxial tension, and bend tests. This presentation compares the interfaces formed in these two free form AM processes for bi-metallic components.
