Exploring the feasibility of a closed-loop industrial symbiosis link through Friction Stir Extrusion-based Additive Manufacturing
A novel approach combining friction stir extrusion-based chips recycling and additive manufacturing was investigated to assess its suitability for a closed-loop industrial symbiosis. Recycled wires made from heat-treatable aluminum alloy AA6082 were used as a feedstock for solid-state additive manufacturing. The macrostructure and microstructure of the material were analyzed to reveal the layer formation mechanics and their influence on the micro and macro mechanical properties of the build. The produced material is characterized by a unique temper providing mechanical properties close to AA6082-T4. Finally, the proposed approach was compared with competitive technologies in terms of deposition rate and energy consumption.
