The world's largest 3D printer can print a house out of clay

Big Delta is the world's largest 3D printer. This 12-foot unit is designed for construction of cheap houses from scrap at minimum cost of energy. This setup should provide a fast and inexpensive construction of temporary housing for victims of natural disasters.



"Printed" at home can become more and more common as the United Nations predicts that in the next 15 years will require nearly a hundred thousand new homes a day worldwide. Cheap and easy home could be a solution not only for areas prone to natural disasters, but also for developing countries. In addition, this method of construction the most environmentally friendly.

Italian engineering company WASP that produces 3D printers of all sizes, has focused the construction of shelters. In the past year, the 4.5-metre printer, which can work on the clay, mud and natural fibers. Now the company has gone even further, creating a record 12-metre Big Delta printer.

With a metal frame with a diameter of 6 meters, a rotating nozzle and a stirrer which maintains the material in a homogeneous condition, to operate the printer requires only 10 watts of energy. The range of possible building materials are very diverse — from clay, which can be enhanced with chemical additives or repellents, to cement, even though this contradicts the "green" strategy of the team. published
