3-D Printing Concrete Houses Contour Crafting

3-D printers can make airplanes and their parts, food and more — why not entire buildings? A professor at the University of Southern California aims to print out whole houses, using layers of concrete and adding plumbing, electrical wiring and other guts as it moves upward.

Professor Behrokh Khoshnevis at USC created a layered fabrication method he calls Contour Crafting, which he says can be used to build a single house or “a colony of houses.” It could be used with concrete or adobe, he says. Khoshnevis has been developing the system for several years and hosted a presentation about it at a recent TEDx event.

It would use a movable gantry taller than the house you want to build. Concrete pours out and is set down layer by layer, like a typical 3-D printer would sinter plastic together. It could be ideal for emergency housing, commercial or low-income structures, but it could also be used to print out customized luxury homes, according to Khoshnevis. Or, he adds, it might be ideal for the moon or Mars. “Contour Crafting technology has the potential to build safe, reliable, and affordable lunar and Martian structures, habitats, laboratories, and other facilities before the arrival of human beings,” his website reads.

Khoshnevis is hardly the only 3-D printing expert advocating this — Enrico Dini, the Italian inventor of the D-Shape 3-D printer, wants to 3-D print moon buildings out of lunar regolith.

On Earth, the automated system could prevent delays, injuries and other labor issues related to human workers. With this system, maybe a 3-D printer could beat the Chinese attempt to construct the world’s tallest building in three months.

I suppose the orginal writer of this story or Rebecca Boyle from PoPSCi didn't want to be the bring of bad news, "...On Earth, the automated system could prevent delays, injuries and other labor issues related to human workers...". via the use of less workers.

The complicated issue of an advancing computerize, robotics and automation society, it inproves life and reduces cost in manufactoring, with and end result of more unemployment.

Is the author of this story really confident it will not bring labor issues with the unions, really?

There will always be room for the workers to make,run, fix or program the automated systems.

So why not use 3D printing to make the tallest skyscraper in the world essentially printing a floor at a time and work your way--right up to the moon!

This is a great idea if only for the architectural potential. A track home is a track home, but do they all have to be so square (literally and figuratively)? I would love to see what someone like Frank Lloyd Wright could do with the technology.

As for the potential loss of jobs, there is potential for loss but I see more in potential for gains. The machines must be built, for now that still requires human hands and workmanship. How about a new manufacturing sector based on 3D printers both large and small?

I ask anyone who complains about the loss of employment....Should we just not have even invented the wheel then? Purposeful inefficiency is madness, and spits in the face of human intelligence. The very last thing we need to worry about is making things too easy.

For the billionth time, Kingdom Tower will be taller and nicer than the cheap 838m chinese tower. Do your homework Boyle.

838m CVS for that matter.

What is this?! A house for ANTS?!? It has to be at least... 3 times bigger!

:-D

I wonder how the concrete sets if it's poured in such small layers. There might be quite a few pieces in the puzzle that need 'old-style' builders, like roofs.
As for unemployment, if we create a society where automated processes take care of 90% of our needs, wouldn't it be easier if we ALL just work 10% of the time we work now and enjoy our life instead of fighting for 60h/week jobs and call the others '90% unemployed'?

I am for robotics-obviously, automation and manufactoring and I am for employeeing people. In the great scheme of things it is an economic social engineering complicated issue.

HE'S ABSOLUTELY RIGHT!!

LOL, very nice reference, Simon!

Wow OK man thats like the coolest thign I hever ever seen!

Two Words VENUS PROJECT

Already in an economy suffering a job shortage, this is a great way to make it even worse! Go technology! Too bad people don't realize that not everyone will be able to work, and that calling them entitled for using government programs is displaced aggression. It's not their fault, but we blame them so easily. This project will enable rich folk to keep even more of their money, prevent them from needing to spend it to move the economy, and pretend like it will 'trickle down' to the proles.

Great concept, though.

Robot..are you from the 50s or something? It has been shown pretty thoroughly that in general, the workforce is FAR better off due to automation.

i see this technology being used for evil in the future. hopefully tourist dont get a hold of it.

Ummmm too late. It's free and opensource.

JediMindset,
I am glad to you blogging. This technology will be taken over by the mainframe IBM Blue once it becomes seflware to begin creating the new robotic world order, as well as taking control of the new robotic drones being produced in the world.

what if we use it just to make low-income housing with solar panels so their rent is low AND have no power bill. If you build enough of them they will give power back to the community, thus making low income housing pay it's way in power for the rest of the working community.

@Robot,

yeah robots will be our rival species on this planet. but soon the annuaki are returning. there might be a war in the distant future between aliens and robots/cyborgs!

@wolfproud,
good idea but big brother wont let it happen, they would lose a LOT of money....

"will enable rich folk to keep even more of their money"
Yes, you said it best. It is their money, their property and no one should have the right to take it from them.

Considering the rather low cost of wall frames, rebar, and standard concrete - how could this be cost effective?

Sure, you don't have to rent or construct frames, but the cost in special (I am assuming special) mix concrete alone would likely cover that.

Add in programming, the footing requirements that would still need to be initially met, and a host of other elements that would still need traditional installation (plumbing, electrical, telecommunication, etc).

There is a reason most houses are not made of concrete - lumber and gypsum are still more cost effective, easier to maintain, and far easier to modify or repair.
