This small home may look plain, but it represents a significant achievement in rapid construction. A Chinese company has demonstrated the capabilities of its giant 3D printer by rapidly constructing 10 houses in less than 24 hours. Built from predominantly recycled materials, these homes cost less than US$5,000 and could be rolled out en masse to ease housing crises in developing countries.
If you’ve been to a major city in China recently, you’ll have noticed a theme. Construction is absolutely rampant, with skyscraper after skyscraper going up as cities scramble to deal with a massive population that’s urbanizing at an unprecedented rate.
Outside the major urban centers, there’s still a vast need for quick, cheap housing, and Suzhou-based construction materials firm Winsun has stepped forward with a very impressive demonstration of rapid construction by using 3D printing techniques to build 10 small houses in 24 hours using predominantly recycled materials.
Rather than printing the homes in one go, Winsun’s 3D printer creates building blocks by layering up a cement/glass mix in structural patterns (watch the process here). The diagonally reinforced print pattern leaves plenty of air gaps to act as insulation. These blocks are printed in a central factory and rapidly assembled on site.
The printer is 6.6 m (22 ft) tall, 10 m (33 ft) wide and 32 m (105 ft) long. Its print head looks somewhat like a baker’s piping gun as it lays out the building mix.
Each small house takes very little labor to assemble, and costs as little as US$4,800. Winsun hopes to make them available for low income housing projects.

I think that is neat. I think it could help people who want to live in a smaller house. There is a trend among some to live small, small houses to tiny houses.
I'm in New Zealand and this kind of thing would be *very* useful down in Christchurch as they rebuild after the 2011 quakes. They are making progress down there but it is *slow*.
The Japanese would have got a few truckloads of these 3d printers after a quake and would have a city pretty much rebuilt in a year or so. A pity that Christchurch has been so slow with its rebuild.
I believe that the councils of every city in NZ should be required to put aside "x" thousand acres of land outside their towns for emergency housing. (This land could be used for other purposes e.g. farming - in the meantime but would be used for housing in a major emergency). If this were done (and if a few 3d printers were bought) then a place like Christchurch would be rebuilt in no time! *So what* if the hastily-built structures had a slight lean on them or whatever? They would still be functional. Simple, basic-but-effective housing for people to stay in while they got their lives back together.
