3D printer inventor claims house can be built in 24 hours

The inventor of a 3D printer who claims it could construct a home in 24 hours has won a global design competition.

Contour Crafting, a computerized construction method that rapidly 3D prints large-scale structures directly from architectural CAD models, has been awarded the grand prize of US$20,000 (£12,360) in the 2014 ‘Create the Future’ design contest.

The concept aims to automate the construction of whole structures and radically reduce the time and cost of construction. The design judges said: “The large-scale 3D printing technology is revolutionary to the construction industry and could lead to affordable building of high quality, low-income housing; the rapid construction of emergency shelters; and on-demand housing in response to disasters.”

Behrokh Khoshnevis, a professor at University of Southern California, who invented Contour Crafting, said: “Bringing 3D printing to construction is bringing a concept to a proven application. For many years, building has been done with concrete foundation blocks, brick laying, structural framing, and so on.

“This recognition will help me greatly in furthering the project.”

Contour Crafting was among 1,074 new product ideas submitted in the design contest, which was established in 2002 to recognize and reward engineering innovations that benefit humanity, the environment, and the economy.
