As highlighted here previously, China is clearly not the only country exploring the wonderful world of 3D printing and it's application to housing. Sadly the loser will be the average construction worker.
The Institute for Advanced Architecture of Catalonia in Barcelona is working on a set of robots that will soon be able to build complex structures by extruding layers of concrete, a process that might be a bit slow but that will allow strange, unique shapes to be formed using concepts popularized by plastic 3D printers.
The team, led by Sasa Jokic and Petr Novikov, has created small robots, called Minibuilders that perform various tasks. The Foundation Robot lays down a structure base while the Grip Robot sits at the top of the foundation and runs around it, laying down a bead of cement and instantly curing it so it can maintain its upwards motion. Finally a Vacuum Robot clings to the side of the object and lays down perpendicular sw
