New impact printing technique can build structures, offers greener alternative to concrete and 3D printing

Impact printing, a robotic construction method developed by ETH Zurich, offers a sustainable alternative to traditional building techniques. This process uses earth-based materials, rapidly depositing a special mixture at high speeds to create structures. It's faster than 3D printing and doesn't require pauses between layers. The method has built walls and columns up to 2 meters tall without chemical additives. Researchers aim to commercialize the technology within three years, potentially revolutionizing sustainable construction.
