Ladies and Gentlemen, I present you the Stone Spray project, an eco-friendly robot three-dimensional printer that exploring the viability of utilizing soil as a building material. Stone Spray is a new construction method which uses soil as the base material and a liquid binder to solidify the soil granules. It uses a jet spray system to deposit the mix of soil and binder, for constructing architectural shapes. Currently, the ability to erected actual buildings is out of the robot’s reach, its team has managed to print a series of scaled sculptures (from stools, pillars and load-bearing arc structures) made from sand, soil and their solidification compound.
Stone Spray is a project created by architects Petr Novikov, Inder Shergill and Anna Kulik, under the Institute for Advanced Architecture of Catalonia and supervised by Marta Male-Alemany, Jordi Portell and Miquel Lloveras, along with professional advisors Santigo Martin from Vortica and Guillem Camprodon from Fab Lab Bcn. The machine’s jet-spray nozzle appears to have an easier experience creating objects over some type of per-existing scaffolding, however the team aims to design structures that won’t need any type of extra support. “We want to push further the boundaries of digital manufacturing and explore the possibilities of an on-site fabrication machine,” the team writes on the Stone Spray project’s homepage, citing makeshift printed bridges (see above) or an on-beach canopy as probable applications of this new technology. I’m not sure if you can have a more green/sustainable building material than the Earth itself, but the robot that is used for this procedure is powered by solar energy. Check out the video below to witness the Stone Spray project in all of its glory.
