As anyone who has ever built or even renovated a house knows, building produces a lot of waste. From surplus wood and bricks to more hazardous electrical wiring, lead and asbestos, in most developed countries, building waste makes up between 10 to 15% of all landfill. Given how toxic these materials can be, this is cause for worry–even simple plasterboard is hazardous once landfilled, as its components break down and release hydrogen sulfide, a toxic gas.
Of course, there is the potential to recycle many of materials, but a better solution is to create less waste in the first place, via 3D printing.
One Chinese company has done just that. WinSun Decoration Design Engineering has harnessed 3D-printing technology to build 10 one-story houses in a day — a cheaper, faster and safer alternative to more traditional construction.
The houses were built in Shanghai using four giant 3D printers, which produce a mix of cement and construction waste to construct the walls layer by layer, a process much like how a baker might ice a cake.
They may not be the most beautiful constructions in the whole world, but they are probably amongst the least wasteful–and they’re cheap, too. WinSun CEO Ma Yihe said: “Such a new type of 3D-printed structure is environment-friendly and cost-effective.”
Whilst the company’s constructions are fairly basic and of course, these images show the unfinished product–surely more beautiful architecture–and less wasteful home building–will be on the way soon.
