Scientists Found a 3D Printing Method to Make Metal 20x Stronger

EPFL scientists have created a breakthrough 3D printing method that uses hydrogels as templates to produce ultra-dense, durable metals and ceramics. The process builds a gel scaffold that is later infused with metal salts and converted into nanoparticles, then heated to reveal the final solid form. The resulting materials are stronger and less prone to [...]
