You might have heard already that 3D printing and architecture are a good mix by the work of Sebastian Bertram. He found a way for a 3D printer to print actual houses. But now there is a new development, the Stone Spray Robot. This is a robotic 3D printer that produces architecture out of soil. Preferrably the soil on location where needs to be printed. This research project by Anna Kulik, Inder Shergill and Petr Novikov, is aimed at finding means of proposing new eco-friendly, efficient and innovative systems to 3D print architecture.
As the video shows, the Stone Spray collects its filament (the sand) on site and then sprays it from a nozzle in combination with a binder component. As soon as the mixture hits the surface it solidifies to create the model.
The cool thing is, as this video shows, that this Stone Spray Robot can print multi-directionally. So it can also print on vertical surfaces. The images below show some of the models they printed to test multi directional spraying and architectural possibilities.
