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.
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
It is "basically scaling up 3D printing to the scale of building," said Khoshnevis.
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.
process, a single house or a colony of houses, each with possibly a
different design, may be automatically constructed in a single run,
embedded in each house all the conduits for electrical, plumbing and
The potential applications of this technology are far reaching including in emergency, low-income, and commercial housing.
technology may potentially reduce energy use and emissions by using a
rapid-prototype or 3D printing process to fabricate large components,
according to the project website.
Featuring robotic arms and extrusion nozzles, a computer-controlled gantry system moves the nozzle back and forth.
research also addresses the application of Contour Crafting in building
habitats on other planets. Contour Crafting will most probably be one
of the very few feasible approaches for building structures on other
planets, such as the Moon and Mars, which are being targeted for human
colonisation before the end of the new century," researchers said on the
With the process, large-scale parts can be fabricated quickly in a layer-by-layer fashion.
chief advantages of the Contour Crafting process over existing
technologies are the superior surface finish that is realised and the
greatly enhanced speed of fabrication, according to the project website.
