| Abstract Scope |
Multi-material wire arc additive manufacturing allows for the creation of parts with higher cost materials only where they’re needed, such as tooling surfaces and other wear-prone areas, and lower cost materials for the bulk of a part. However, current methods result in abrupt interfaces between the materials with very little transition. This can cause incomplete bonding, especially with dissimilar material. The use of functionally graded materials allows for a smooth, more gradual transition that allows for better bonds and more seamless parts. By leveraging existing technology designed to increase deposition rate in MIG welding processes, we have created a system that allows for the deposition of functionally graded materials using a single MIG torch. An overview of the system and its progress from proof of concept to prototype system will be presented along with initial results including a part printed with a smooth transition between two different materials. |
