A 3D printed house takes shape in rural China ”
A rural house in Hebei Province (northern China) has recently become famous for being the first 3D printed house in this rural area of China, built “scan by scan” with giant construction 3D printers.
With vaulted ceilings and concrete exterior walls decorated with woven patterns, Zhao Xiujuan’s home in Wujiazhuang Village of Zhangjiakou, the co-host city of the 2022 Winter Olympics, covers an area of 106 square meters and has three bedrooms, a kitchen and a toilet.
When Xu Weiguo, professor at the School of Architecture at Tsinghua University, came up with the idea of building a 3D printed farmhouse in Wujiazhuang, the villagers expressed concern.
“How do you print a big house? “” Is it strong enough? Despite the skepticism of his fellow villagers, Zhao asked Xu and his team to rebuild his old house with 3D printing technology.
At the construction site, 3D printing robotic arms built concrete materials layer by layer to form the foundations and walls. After the roof was printed separately, it was fixed to the wall by a crane.
Construction of the house was completed in two weeks.
The Kickstarter brought success and swept away worries. “There were only two people on each device. They hit the button, and then a house was built. It’s incredible, ”said a villager without giving his name.
In recent years, the Chinese 3D printing market has grown rapidly, and the technology has been widely used in aerospace, construction, automotive, shipping, and others.
Experts have even tried to take 3D printing to the next level, building 3D printed houses in villages, improving the rural living environment.
“This technology can save labor and construction costs while increasing efficiency and quality,” Xu said, adding that it can retain the design and construction of traditional houses while creating new features. beautiful irregular curved surfaces.
Before the 3D printed farm took shape, Xu and his team applied 3D printing technology to build other structures at home and abroad, including a 26.3-meter-long pedestrian bridge in Shanghai. .
China has made continuous efforts in technological innovation to transform and modernize the traditional construction industry.
In July 2020, a directive issued by 13 central departments called for efforts to integrate smart building technologies throughout the industrial chain and set short and long-term goals for high-quality development of the industry. .
“At present, there are still a large number of houses and infrastructure to be built in China. Smart technologies can solve the problem of labor shortage faced by the construction industry, freeing workers from heavy labor, ”said Xu.
