China installs world’s first 3D-printed bus stop

China has unveiled 3D-printed bus stations in the eastern metropolis of Shanghai which, according to local media, are the world’s first of this kind.

Shanghai has installed 16 of these new bus stops in the Fengjing Town area of Jinshan District. At 5.1 meters long, 1.5 wide and 2.7 tall, each of them can accommodate over 10 passengers.

Each bus stop is made up of renewable materials taken from construction waste, making them environmentally-friendly.

They were printed with industrial waste from demolition, recycling and steel slag, said Ma Yihe, chairman of Yingchuang Building Technique (Shanghai) Co., ltd., the company that builts the bus stations.

The technique used to print with construction waste is the world's first, according to the company. No harmful substances are produced during the printing process and even the remaining materials can be utilized again.

Materials come first in 3D-printing, said Ma. “Using construction waste as the printing material requires strict classification and process, and provides better quality than traditional materials.”

“The impurity that gets separated is some dust, which can be used as plant soil. We can also compost the mixture of the dust, grass and fruit kernels. It is completely recycled,” Ma added.

The technique is also very efficient. Such a bus stop can be printed within a single day, and an experienced operator can run three printers at the same time. Once complete, installation takes less than two hours.

The local government has been promoting such sustainable projects in infrastructure construction. Besides for 3D-printed bus stops, roads and multi-functional buildings are also expected to be 3D-printed in the near future, with an aim to converting the industrial waste in the Fengjing Town and the whole district into 3D- printing materials and making the area eco-friendly.

It doesn't look good.

It's not yet being finished.

The raw materials are recycled construction waste, so I don't think the builders pay much attention to design.

Or maybe it was deliberately designed to look like recycled construction waste.

I think the picture was taken in its assembly phase. Once paint is applied and surroundings are developed, it will look much cooler.

Just my opinion, but from what I saw from the third picture, that bus stop design looks similiar like a type of hollow brick (not sure about the name since I am not a civil engineer) that commonly used in skyscraper construction. So I guess maybe it was an intentional design to look like a construction waste.

Indeed, could be. If some paint is applied, the look will change considerably. But I think they want to emphasize the environmental aspect.

nice ...environmentally friendly and time efficient construction
