| Abstract Scope |
Additive friction stir deposition (AFSD) is an emerging solid-state large-scale additive manufacturing (AM) process that deposits metals layer by layer below their melting temperature by employing a non-consumable rotating tool with axial feed of bar stock to generate friction and induce plastic deformation. The solid-state nature of the process results in lower residual stresses and fewer defects, such as porosity and cracking, as compared to traditional beam-based AM processes, including powder bed fusion and directed energy deposition. These unique features make AFSD a viable process for printing recycled material such as machining chips, shredded metallic waste such as beverage cans, and even metal matrix composites. In this work, we present the design and demonstration of a hydraulic press-based compactor for producing AFSD feedstock from metallic chips collected from machining processes and shredded aluminum cans. This research represents a significant advancement towards achieving sustainability for AFSD processes. |
