3d printing house - 3D printer can build a 2500 sq.ft house in just 24 hours

Scientists claim to have developed a revolutionary new giant 3D concrete printer that can build a 2500 square feet house in just 24 hours.

The 3D printer, developed by Professor Behrokh Khoshnevis from the University of Southern California, could be used to build a whole house, layer by layer, in a single day.

The giant robot replaces construction workers with a nozzle on a gantry, which squirts out concrete and can quickly build a home based on a computer pattern, MSN News reported.

It is "basically scaling up 3D printing to the scale of building," said Khoshnevis.

'Contour Crafting' is a layered fabrication technology and has great potential for automating the construction of whole structures as well as sub-components, according to the project website.
