Researchers pioneer hydrogel-based 3D printing method for low-shrinkage ceramics and metals

A team from École Polytechnique Fédérale de Lausanne (EPFL) has unveiled a breakthrough in vat photopolymerization (VP), demonstrating a hydrogel-based technique that enables the 3D printing of ceramics and metals with far lower shrinkage than previously possible. Published in Advanced Materials on September 24, 2025, the study shows how repeated infusion–precipitation cycles transform printed hydrogel […]
