In this edition of The Future, a private firm in China called WinSun has used its technology to build huge 3D printers that in turn print even huger fully-functioning houses. Their printers can manufacturer 10 in a day. Let's assess.
The WinSun printers are 32 feet by 21 feet, and four of them are needed in constructing one house. The company uses the printers by spraying "a mixture of cement and construction waste to build the walls, layer by layer."
Each house costs under $5,000 to build because of its recycled materials and lack of labor. Chinese construction regulations don't allow 3D printing of multi-story houses yet, but let me repeat that, yet.
They seem kind of livable, if not pretty ugly.
