3D printing building have been built in Qingpu, Shanghai in August 21. Used as a local relocation project office
space. These "print out" wall is special "ink" made with
construction waste. In accordance with the design drawings and computer programs
by a large 3D printers. It just takes 24 hours to print out all 10 houses.
The house is not big, only two storey high. But special things
there are not a piece of brick in the building, the wall showing structure by
stacking layers of material made of cement, each layer is about 2 cm high.
The printer is 6.6 meters high, 10 meters wide, 32 meters
long. The bottom surface area is as much as a basketball court. And the printer
can also extend the length, fully opened enough to have 150 meters long.
Introduction
of the Inventor, the "Ink" is a specially treated glass fiber
reinforced concrete material, its strength and useful life is much higher than
reinforced concrete. Hollow wall not only greatly reduce the weight of the
building itself, but also free to fill insulation materials. The "Ink
"will soon solidified after extrusion, ensure the printer can print
continuously.
After the house have been built. Installing windows and
doors, lined up all kinds of wire and pipe. Follow by the floorings and
furniture from the 3D, the owners can move in in a month. In addition, the use
of 3D printing technology, building is very environmentally friendly, and also
cost 50% cheaper.
