It's hard to keep up with all the 3D-printing capabilities in the world right now -- 3D chocolate, glass and now, even a 3D-printed house. This massive 40-foot tall machine called 'Big Delta' was designed by an Italian company 'WASP' and can build large scale homes out of mud and clay.
The 3D-printed house built by the machine costs very little money and expends very little energy to create, making it relatively eco-friendly as well. The printer's nozzle doubles as a mixer and adds chemicals that allow the mud and clay to be structurally reinforced.
Intended for disaster relief, this quick and inexpensive way of building houses is revolutionary for third world countries that often get rocked by natural disasters. Short term aid like food and medical supplies are often delivered but a way to build back people's homes and communities efficiently is ground-breaking. Looking towards the future, this machine could even have potential to build concrete homes around the world or out in space.
