3D printed houses built in Shanghai from fiber reinforced cement

It looks like a concrete bunkie, this little building in Shanghai. In fact, it’s a 3D printed house made by WinSun out of glass fiber reinforced cement.

The printer generates a sort of open web joist structure that is probably strong and light; the layers are then bonded together into the structure. It’s an interesting system in that there is room for wiring and insulation in those open webs.

Using computer and 3D modeling software, the designs of the building can also take into account additions like insulation materials, plumbing, electrical lining and windows, which can then be easily outfitted once the rest of the structure is solid and standing.

In addition, it is very impressive that the printing material is recycled construction waste, industrial waste and tailings. WinSun plans to build 100 recycling factories in the country, one in every 300km, to collect and transform the waste into materials for 3D printing through special handling, processing and separation technology. “There will not be any waste from the construction of new buildings.” said WinSun CEO Ma YiHe. WinSun expects 3D printing will save construction companies up to 50% on the cost. … (Read more)
