Stone Spray research project wants to print bridges with sand, solar power

Envious of your pet hermit crabs' 3D-printed domicile. Maybe you should cast your green eyes upon the Stone Spray project, an Eco-friendly robot printer that's exploring the viability of soil as a building material. Although making actual buildings is a bit out of the robot's reach, its team has managed to print a series of scaled sculptures (such as stools, pillars and load-bearing arc structures) out of sand, soil and a special solidification compound.
