Behrokh Khoshnevis, professor of industrial and systems engineering as well as civil and environmental engineering, is creating a machine that will construct full-scale civil structures within hours -- that is, 3D-printing an entire building. Khoshnevis, also the Director of the Center for Rapid Automated Fabrication Technologies (CRAFT), is developing the technology that will make building a house within 24 hours possible, including conduits for electrical, plumbing, and air-conditioning.

Below are some recent media stories that feature Khoshnevis and his Contour Crafting technology.


The University of Southern California is testing a giant 3D printer that could be used to build a whole house in under 24 hours. Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a nozzle on a gantry, this squirts out concrete and can quickly build a home according to a computer pattern.

Construction has always been a three-dimensional activity. While the representation of the intent of construction has been liberated "virtually" into 3D digital models and rotatable 3D representations, accurate physical representations of design intent have been achieved, until only recently, either through the artistry and skill of a scale model-building or by building full-scale mock-ups of the ideas captured by the design documentation.

Creating structures in space that astronauts can live in has become a priority for NASA. With a manned mission to Mars on the agenda, and plans for lunar exploration underway, scientists are increasingly looking towards unconventional construction methods. The most promising of these is 3D printing, which could make building a lunar home in space a matter of pressing a button and letting a robot do the work. (View article)
At The University of Southern California, Professor Behrokh Khoshnevis has built a colossal 3D printer that can build a house in 24 hours. Khoshnevis's robot comes equipped with a nozzle that spews out concrete and can build a home based on a set computer pattern. (View article)
Do you remember our post on the world’s first 3D printed Canal House in Amsterdam? Well, if that project was estimated to be completed in a matter of months- an impressive achievement- a new 3D printer is being planned as we speak, with the purpose of building a house in less than 24 hours. The master mind behind this impressive goal is Professor Behrokh Khoshnevis from The University of Southern California. (View article)

Imagine being able to lease a 3D printer to build your entire house. The technology, called Contour Crafting, is already here and can build a 2,500-square-foot home in 20 hours. The massive robot printer was invented by University of Southern California professor Behrokh Khoshnevis, who says that the technology is so versatile that it can be used to build homes in slums or human habitats on Mars.

Scientists claim to have developed a revolutionary new giant 3D concrete printer that can build a 2,500-square-foot 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. (View article)
Imagine reviewing the blueprints for your dream home, putting down your down payment and having it built to order all within one day. Scientists in California say not only is that possible, but they can already make it happen. (View article)

Scientists in California say new technology will soon allow massive 3D printers to build entire multi-level houses in under a day. University of Southern California Professor Behrokh Khoshnevis has for years been working on a building printing technology called “contour crafting,” and has earned accolades from the likes of the National Inventors Hall of Fame and even NASA for his efforts.

The space agency supports 3D printing technology and building houses in space where astronauts can live is a priority for NASA. 90% of materials needed for construction are already on the Moon, so it would be easy to transport the remaining 10% from Earth in a spaceship. An idea expressed by Professor Behrokh Khoshnevis University of Southern California. (View article)
