| Abstract Scope |
Additive manufacturing (AM) techniques represent a novel approach to production that combines the potential for remarkable technological results with the possibility of approaching a more sustainable use of resources, including both energy and materials in powder form. This work presents an approach to reduce the environmental impact of AM powders, with a particular focus on the vacuum inert gas atomisation (VIGA) of a 5.xxx series aluminium alloy powder. Metal powders are prepared from secondary industrial waste in chip form collected from a wire drawing process and characterised in terms of microstructure, light element content (O, N, H, C, S), structural, rheological and optical properties. An overall evaluation of the embedded CO2 is estimated and the savings compared to powders obtained from a secondary alloy. |
