Chinese companies have been known to build major real estate projects very quickly. Now, one company is taking it to a new extreme.
Suzhou-based construction materials firm Winsun New Materials says it has built 10 200-square-meter homes using a gigantic 3-D printer that it spent 20 million yuan ($3.2 million) and 12 years developing.
Such 3-D printers have been around for several years and are commonly used to make models, prototypes, plane parts and even such small items as jewelry. The printing involves an additive process, where successive layers of material are stacked on top of one another to create a finished product.
