3D printing buildings and other structures with soil and binder

Stone Spray is a promising-looking 3D printer that is intended to produce building-scale structures by combining soil with binder from a spray-nozzle. Unfortunately, all the meaty tech information is locked up in a weird "book" player that doesn't work well on my screen, but you can get a general idea from the video above (I recommend scrolling at 10-20 second intervals and turning off sound).
