ETH Zurich’s new robot is shaking up construction by 3D printing walls from local clay and silt—no cement, no frames, just pure impact printing. This could mean faster, greener buildings with less carbon footprint. But would you feel safe living or working in a structure built this way? Is this the future of sustainable architecture, or are we not ready to ditch cement just yet? #Tech #3DPrinting #GreenTech
