Building a 2,500-square-foot house in less than 20 hours? It sounds like a tall tale, but a professor at the University of Southern California says it is absolutely possible. He would toss out traditional building practices and replace them with a single 3D printer.
It's called contour crafting, creator Behrokh Khoshnevis, the director of the manufacturing engineering graduate program USC, tells CBS News.
"Construction the way its done today is very wasteful," he explained in a presentation at TEDxOjai. "Our solution benefits from advanced technology...it is essentially a way of streamlining the process of construction by benefiting from the experience we have gained in the field of manufacturing."
The 3D printer lays out concrete and interlocking steel bars as it builds a structure. Khoshnevis says that the printer can handle the plumbing, electrical networks and flooring for multi-story buildings....

If we can 3D-print a better home, could we possibly look forward to 3D-printing a better government?
Only if we can 3D-print working brains for the liberal voters.
That must be on BIG printer.
Maybe that starts with 3d printing guns.
Back in the 60s Robert Heinlein pointed this. Out. He wrote imagine what a car would cost, and how long it would take to build if like a house, a bunch of raw material was transported to your location and put together from scratch there....
“That must be on BIG printer.”
There is an animation on the linked page.
It looks very feasible. Save time, labor, materials, etc.
The equipment looks fairly straightforward, and not too “big.”
The term “3D Printing” is misleading. It is more like an automatic building machine.
Interesting, but it’s probably more cost-effective to use the “printer” to construct prefabricated house pieces, and then truck the completed pieces to the building site and assemble them, rather than truck the printing assembly around.
The thing I’m waiting for is for prefabrication or other automated assembly to actually start reducing house prices. Right now, a nice custom prefabricated costs as much if not more than a regular stick-built (and I’m not talking “Palm Harbor”; I mean built to the same standards as houses like Lennar and so on).

Palm Harbor also makes modulars.
Palm Harbor isn’t all that much better than a trailer. It’s the “upscale” modular/prefab stuff that ought to be cheaper than it is (and Palm Harbor isn’t all that much cheaper than stickbuilt either).
I wasn’t touting their quality, merely saying that they do build modular, as did Oakwood way back when I worked for them. We had a triple-wide manufactured that wasn’t half bad. Sunken living room, gourmet kitchen, nice master, etc. Sold a few of them to snowbirds.
I surmise 3D printing may be to manufacturing what the computer was to data processing, or communications, to a very strong degree.

I doubt if I’ll ever understand what a 3d printer is.
However it works, lots of Mexicans are going to have to learn how to use them if they wanta’ keep building houses.
But...but...what about the Mexicans?
They can run the building machines. . .in Mexico.
