WinSun Decoration Design Engineering based in Shanghai, China, has created a small village of 10 houses in less than a day. Each home measures about 2,100 square feet and costs less than $5,000. Although assembled by workers, the components of the home were fabricated using a 3D printer that is 490-feet long, 33-feet wide and 20-feet deep. The machine spews out layers of concrete, which includes tailings, recycled construction and industrial waste and glass fibers.
