Mish’s Global Economic Analysis has some big news out of China.
Chinese construction firms can 3-D print 10 low-cost houses a day with machines that add layer after layer of quick-drying cement in a process called “contour crafting”.
A private company in east China recently used a giant printer set to print out ten full-sized houses within just one day.
The stand-alone one-story houses in the Shanghai Hi-Tech Industrial Park look just like ordinary buildings. They were created using an intelligent printing array in east China’s city of Suzhou.
The array consists of four printers that are 10 meters wide and 6.6 meters high and use multi-directional automated sprays. The sprays emit a combination of cement and construction waste that is used to print building walls layer-by-layer.
Ma Yihe, the inventor of the printers, said he and his team are especially proud of their core technology of quick-drying cement. Ma said he hopes his printers can be used to build skyscrapers in the future.
This technology allows for the printed material to dry rapidly. Ma has been cautious not to reveal the secrets of this technology.
