Summary

Story summary

École Polytechnique Fédérale de Lausanne (EPFL) researchers developed a hydrogel-based 3D printing method to produce ultra-dense metals and ceramics, claiming materials up to 20 times stronger than traditional methods.
The process prints a hydrogel framework, infuses it with metal salts, then heats to remove the hydrogel.
The technique is described in Advanced Materials.
The team aims to speed processing and increase density for energy, sensors, and biomedicine.
