Product 7 months, 2 weeks agoSwiss Researchers Created A World-First Low-Cost Method For 3D Printing Metals Using Hydrogels Instead Of Metal Powders Or Molten Alloys. They Print A Polymer Framework, Add Metal Ions, Grow Nanoparticles, Then Heat It To Form Pure Metal. The Result Is Up To 25× Stronger & Shrinks Only 20%, Compared To 60–90% Shrinkage In Older Methods.
Scientists grow metal instead of 3D printing it — and it’s 20x stronger | ScienceDailyScientists at EPFL have reimagined 3D printing by turning simple hydrogels into tough metals and ceramics. Their process allows multiple infusions of metal salts that form dense, high-strength structures without the porosity of earlier methods. Early results show materials 20 times stronger with much less shrinkage. The breakthrough could lead to efficient production of complex energy and biomedical devices.
