3D-printed wall panels absorb moisture, regulate humidity for healthier homes

Researchers at ETH Zurich have developed 3D-printed wall and ceiling panels that naturally absorb excess moisture from indoor air. The panels are made from marble quarry waste and a geopolymer binder, reducing humidity and improving comfort in crowded spaces. Simulations show the panels can decrease humidity-related discomfort by up to 85% compared to standard walls. This innovation could significantly reduce the need for energy-intensive mechanical ventilation systems, potentially lowering greenhouse gas emissions over a 30-year lifespan.
