Additive Manufacturing of Metals

We develop sustainable, sinter-based metal additive manufacturing feedstocks using recycled and critical metal powders combined with bio-based polymer matrices for low-cost material extrusion 3D printing.

Our work focuses on high metal loading formulations, followed by debinding and sintering to produce fully dense metallic components. We investigate processing–structure–property relationships across all stages to ensure printability, avoid defects, and achieve high-performance parts.

This approach enables the valorization of recycled metals, reduces reliance on virgin resources, and supports low-carbon, resource-efficient metal manufacturing.
