3D Printers To Build Houses
gbjbaanb writes to point out an article in the Sunday Times describing two separate programs where robots are being developed to build houses. The Los Angeles project is farther along than the one in the UK, but the article provides more details on the techniques employed in the latter. Liquid concrete and gypsum will be sprayed from nozzles in a manner analogous to an inkjet printer. From the article: "The first prototype — a watertight shell of a two-story house built in 24 hours without a single builder on site — will be erected in California before April. The robots are rigged to a metal frame, enabling them to shuttle in three dimensions and assemble the structure of the house layer by layer. The sole foreman on site operates a computer programmed with the designer's plans... Inspired by the inkjet printer, the technology goes far beyond the techniques already used for prefabricated homes. 'This will remove all the limitations of traditional building,' said [an architect involved with the UK project]. 'Anything you can dream you can build.'"
As soon as HP hears about this, we'll have $15,000 Housejet cartridges.
"Anything you can dream you can build."
That seems overly optimistic. I think there are a few laws of physics that would disagree.

How many people can read hex if only you and dead people can read hex?
What happens if you print a test page? Does it build a giant HP logo?
A few links could of course have helped this article... I think contourcrafting.org seems to be more or less the right page for the California project. The videos and animations are quite worth seeing.
For the Loughborough one, the closest I could come up with was Dr Soar's website...
The biggest problem we have here in the third world, other than education, is housing.
Currently what happens is that -- in the urbunising of people -- most people tend to build with whatever materials they have available leading to shanty-towns all over Africa with people living in shack-like hovels.
If this technology is able to deliver, and deliver cheaply, we might just have one of the technologies needed to bootstrap Africa out of abject poverty.
The other major problem, education, might just be in the hands of the OLPC guys...

It will probably be cheaper to buy new robots that come with cartridges.

Much more details.
"If you ask a bricklayer to lay bricks in anything other than a straight line, you'll run into problems," said Soar. "But if you ask the robot to make a squiggly line it really doesn't care." I'm sure there are many a brickmason who can run bricks in many formations besides a straight line. I'm positive on this fact because the brickmasons who did my foundation was anything but straight.
There are no loopholes. It's either legal or it's not.
The machine builds houses in 1/200 of the time at 1/5 of the cost. Who wants to bet the price of houses will stay around the same level? Almost any random 2-bedroom house in the Netherlands costs a quarter of a million euros nowadays. The same size house sells around a hundred thousand in Portugal. In Canada, this price range can get you a 5-bedroom house. Based on these numbers, it would seem to me that the cost of building the house itself is just a minor factor in the price of a house.
