Story summary

École Polytechnique Fédérale de Lausanne (EPFL) researchers have developed a new 3D printing technique that yields strong, lightweight metal and ceramic structures.
The method builds a hydrogel framework infused with metal salts and converted into nanoparticles.
After cycling, removing the hydrogel leaves dense objects that resist 20 times more pressure and shrink less, with applications in biomedical devices and energy technologies as automation progresses.
