In a latest addition to a host of things that 3D printers can do, a revolutionary concrete printer can reportedly build a 2,500-square-foot home layer by layer in a single day.

The University of Southern California is testing a giant 3D concrete printer that could potentially replace human workers by following a computer pattern for constructing a house.

According to MSN, professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a nozzle on a gantry and squirts out concrete to build a house.

Khoshnevis explained that the technology, known as Contour Crafting, basically scales up 3D printing to the scale of building and could revolutionise the construction industry.

Contour Crafting could cut down the cost of home-owning by making it possible for millions of displaced people, during emergency situations, to own a property.

Brad Lemley from Discover Magazine observed that the technology would require workers to lay down two rails a few feet further apart than the eventual building’s width and a computer-controlled contour crafter would take over from there to create the entire structure.

The report said that Contour Crafting also produces much stronger structures than traditional building methods and by simply changing the computer pattern, innovative structures can be built, including curved walls, without incurring additional costs.
