In what was first blown off as an attempt at an April Fools Joke, this story seems to be legit. I even saw people posting this at this forum saying it was a joke, however the story does check out. 3Ders released some pretty amazing photos of these 3D printed concrete homes.The homes were printed by a Chinese company called Winsun, using a 490 feet long, 33 feet wide, and 20 feet deep, 3D Printer. A majority of the concrete material used by the printer is derived from concrete waste and glass waste after tearing down other buildings and structures. The homes were not printed in the location they will eventually reside, but instead printed in the Winsun Engineering and Design factory and will be transported to a final location. The homes will cost as little as $4800, and provide housing for some of the poorest residents in the country.These 3d printed homes will not be tiny. Some will be as large as 2100 square feet in size. These structures still require metal roofing, windows, and a few other elements to make them structurally sound, however the main frames of these homes are printed with a very strong material.Here is the website of the company 3D Printing these homes. It's in Chinese, and does not include the images I have posted below: http://www.yhbm.com/index.aspx
