Additive manufacturing of micro-architected metals via hydrogel infusion.

ABSTRACT: Metal additive manufacturing (AM) enables the production of high value and high performance components¹ with applications from aerospace² to biomedical³ fields. Layer-by-layer fabrication circumvents the geometric limitations of traditional metalworking techniques, allowing topologically optimized parts to be made rapidly and efficiently^4,5. Existing AM techniques rely on thermally initiated melting or sintering for part shaping, a costly and material-limited process^6-8. We report an AM technique that produces metals and alloys with microscale resolution via vat photopolymerization (VP). Three-dimensional-architected hydrogels are infused with metal precursors, then calcined and reduced to convert the hydrogel scaffolds into miniaturiz
