Stone Spray builds architecture from the ground up ... literally: "As useful as 3D printers are becoming in industrial design, they still aren't exactly eco-friendly and are still mostly limited to small scale objects. You couldn't really use one to print a building just yet, but a group of architects may have taken a step in the right direction with a new machine called the Stone Spray. Using natural soil and sand, the Stone Spray can construct intricate solid structures at almost any location, even on vertical surfaces."
