3D Printed Buildings Speed Up Construction

April 24, 2014

Will the buildings of the future be printed?

3D printed house assemblyChinese construction materials company Winsun New Materials says it has printed 10 houses on its new 3-D printer that cost them about $3.2 million to develop and took 12 years to build.

Winsun’s 3D printer is 6.6 meters (22 feet) tall, 10 meters wide and 150 meters long, the firm said, and the “ink” it uses is created from a combination of cement and glass fibers. In a nod to China’s green agenda, Winsun said in the future it plans to use scrap material left over from construction and mining sites to make its 3D buildings.

3D 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.

Winsun says it estimates the cost of printing these homes is about half that of building them the traditional way.  Although the technology seems efficient, it’s unlikely to be widely used to build homes any time soon because of regulatory hurdles.

Believe it or not, the Chinese firm isn’t the first to experiment with 3D printed buildings.  Architects in Amsterdam are building a house with 13 rooms, with plans to print even the furniture.  The Dutch architect in charge of the project said on the project’s website it would probably take less than three years to complete.
