Giant 3D Printer That Can Build a House in a Day Is Real

“Contour crafting” might just make it as a construction technique

A week ago, we brought a certain building technique to your attention, called contour crafting, which is really a sort of 3D printing technology that uses concrete. Now, the invention seems to be gathering steam.

Not surprising, when the technology allows massive 3D printers to build houses in less than a day's time.

University of Southern California Professor Behrokh Khoshnevis has been working on making this idea reality for years.

The National Inventors Hall of Fame and NASA have both praised him for it, and they aren't the only ones.

The professor figured that, with everything from shoes and clothes to cars being made automatically, only buildings are still being made by hand, and it was about time that stopped being true, hence his invention.

To build a home via Contour Crafting, you first need to level the area where the house will be located, then dig tranches around the perimeter. Said trenches must be filled with concrete.

After that, a system of rails has to be erected on the sides of the foundation, on which the 3D printer is lowered down using a crane. Once the building materials are fed to the printer, you just let it do its job.

The machine layers materials level by level, and can raise the house to a height of about two stories, building upwards as more concrete is spilled out.

Using this process, a single house or a colony of houses, each with possibly a different design, may be automatically constructed in a single run,” the Contour Crafting website states.

If nothing else, our main question regarding this technology has been answered: Contour Crafting does take into account the elements that need to be added after that, like electrical wiring, plumbing, windows, etc. The same goes for the wall paint, but that goes without saying.
