Abstract Scope |
Additive friction stir deposition (AFSD) is a novel and environment-friendly additive manufacturing (AM) process that uses a rotating tool to generate frictional heat and plastic deformation, allowing metals to be deposited layer by layer onto a substrate. This solid-state process eliminates melting and solidification and provides an avenue for upcycling machined metallic chips to produce feedstock rods. This paper presents a chip compactor design integrated into a hydraulic press using a die set and ram carriage. Through the application of controlled compressive mechanical forces under both cold and warm working conditions, the system enables aluminum (Al6061) rods to be produced from machining chips with 86% relative density with respect to wrought Al6061. The chip compactor design is described and its implications for AFSD sustainability within a circular economy model is examined. |
