A 3D printing robot can create a sand bridge that you could fully walk on. The Stone Spray robot can create structures out of sand or soil and solar power. Using this technology you could build a house out of nowhere or a sand bridge in the middle of the desert.
The soil or sand is combined with a binder, which the robot sprays to create an organic form. Unlike traditional 3D printers, the Stone Spray can print vertically and horizontally. This process works best in hot, dry places because sunlight helps set the materials.
The printer was built at the Institute for Advanced Architecture of Catalonia by Petr Novikov, Inder Shergill and Anna Kulik.
