New 3D printing method creates dense metal and ceramic structures

A new 3D printing method allows for the creation of dense metal and ceramic structures. This breakthrough could advance energy, biomedical, and sensing technologies. The technique involves growing metals and ceramics within a hydrogel scaffold. Metal salts are infused and converted into nanoparticles, enabling high concentrations for intricate constructions. This method differs from previous light-based resin hardening. It was developed by researchers in Lausanne, Switzerland.
