The ToZero (Towards Zero Waste in Aluminum BiW Manufacturing) project has successfully demonstrated that aluminium scrap generated during automotive body-in-white (BiW) production can be converted into powder for laser powder bed fusion (LPBF), marking a step towards more sustainable additive manufacturing.
{alcircleadd}Funded under Italy's Accordi per l'Innovazione programme, the project brought together Valland, Politecnico di Torino, Politecnico di Bari and the Fontana Group to assess the feasibility of recycling automotive aluminium scrap into feedstock for metal 3D printing.
As part of the project, Italian additive manufacturing specialist Valland developed LPBF process parameters for recycled AA5083 aluminium powder before producing a topology-optimised automotive structural connection node known as the "Voletto".

According to the project team, the recycled alloy was successfully printed without hot cracking, while the component achieved the targeted levels of mechanical performance and ductility. Through topology optimisation, the demonstrator's weight was reduced from 1.68 kg towards a target of 0.8 kg.
A life-cycle assessment conducted in line with ISO 14040/44 standards found that process optimisation reduced the component's carbon footprint by around 73 per cent, highlighting the environmental benefits of using recycled aluminium in additive manufacturing.
The project also identified a remaining challenge for wider industrial adoption. Valland noted that recycled AA5083 currently prints at a significantly slower rate than the widely used AlSi10Mg alloy, indicating that improvements in productivity will be needed before recycled aluminium powders can be deployed at commercial scale.
