A Chinese company just 3D-printed a mansion

You'll have to see it to believe it, but yes, Shanghai-based WinSun, also known as YingChuang, printed, not just a house, but a MANSION. It's a 3D-printed house! Feast your eyes on... THIS:


WinSun is a high-tech research and development company that creates new materials for construction. They're also the ones behind the Beijing National Aquatics Centre. They created a mansion AND an apartment building in the SuZhou Industrial Park as a showcase for this new 3D printer.


WinSun CEO Ma Yihe told the press that they used a special quick-dry cement to speed up the process and purchased parts for the printer before assembling the machine in a factory in Suzhou.


This is what the house looks like on the inside. A little dark, but nothing some electrical wiring can't fix! Maybe they will 3D print lights too. We joke. 


See those lines? Those were created by the printer piping layer upon layer of special concrete to make the walls. The project was produced by creating parts in the factory that were 7m tall, 10m wide and 40m long, before being joined together at the industrial park.


Aside from the mansion, WinSun also printed an apartment building of the same material.


You're probably wondering if the structures are safe. They are, according the the CEO. The ink/building material comprises concrete, fiberglass, sand and a hardening agent. It's supposed to be flexible, self-insulating, resistant to strong earthquakes and quick-drying. 


This is how the walls are reinforced. The new technology is supposed to save 60% of materials, 70% of time and 80% of labour usually needed to build a typical home. The CEO hopes that this will help create affordable homes across China.


This isn't the first time the giant 3D printer has created homes. As a test, WinSun built 10 one-storey homes in a day. Each 10m X 6.6m home cost under $5,000 to build! But don't hold your breath for your HDB flats to be built in a day. It will take much more R&D before your 20-something floor homes can be built using a 3D-printer.
