Every day there seems to be a new amazing thing that was created by a 3D printer, but one Chinese company might have just topped them all. The Shanghai-based company has stated that they made ten houses with a 3D printer in one day. The printers that the company is using are enormous, roughly 490 feet long and 33 feet wide, and they are not using typical materials found in most 3D printers.

Instead, WinSun Decoration Design Engineering Co printed with a concrete composite that is made up of recycled materials and industrial waste. There is some controversy about the 3D printing claim since the company is 3D printing the pieces and then combining them at the housing plot. It's an impressive feat regardless as each home was made extremely cheaply at under $5,000.
