In August 2022, at the Lingyan Community Health Service Center in Liuhe District, Nanjing City, a two-story building under construction piled up and grew “like a decorated cake” and began to take shape despite its banal appearance, but there. is the high technology behind it all.
This is a truly habitable and deliverable two-story building. It is 3D printed on site and stands 6 meters high and has a usable area of 52.8 square meters. It is led by Shanghai Construction Engineering Group and will serve. as a history exhibition hall after use. Chen Xiaoming, chief engineer of Shanghai Construction Engineering Group, said: “On the path of exploring intelligent construction, large-scale 3D printing construction is the technical direction that Shanghai Construction Engineering Group prioritizes its development.

Truly habitable and deliverable
This 3D printing building, also known as the 3D printing technology test building project of Shanghai Construction Engineering, is one of the demonstration projects of the national key research and development project led by the Shanghai Construction Engineering Group. Shanghai Construction Engineering, Southeast University and Nanjing Jiayi Precision Machinery Manufacturing Co., Ltd. jointly formed a project team. This two-story printed-on-site building will eventually be used as an exhibition hall on the history of Lingyan Community Health Service Center Hospital in Liuhe District, Nanjing.

Printing the entire building took approximately 50 hours. The 3D printing equipment independently developed and manufactured by the project team, self-developed 3D printing concrete materials, and the first designed building structure all laid an important foundation for the smooth implementation of the project. on-site printing.
The equipment currently on site is the first on-site 3D printer in China that realizes the pumping of large aggregate concrete materials. The printing range is 24 meters long, 8.5 meters wide and 6 meters high. The diameter of the print head nozzle is 40.mm and 50mm. Two types of millimeters can achieve intelligent construction by in situ 3D printing of very large structures.
Now that the printing equipment is in place, “effective cooperation” between the printing media is necessary. The 3D printed concrete material independently developed by the project team was used on site, and during on-site 3D printing, it was the first to partially use 3D printed concrete material containing coarse aggregates : ready-mixed concrete containing coarse aggregates has been transported. Thanks to pumping technology. After arriving at the print chamber, it is stirred twice in the print chamber and then extruded through the print head to print its shape.
Using coarse aggregates can not only reduce material costs, but also solve the current problem of easy cracking of 3D printing mortar. The project team also developed solid waste that can be used for 3D printing, which is in line with current development concepts of solid waste recycling, energy saving, emission reduction and environmental protection.
At present, the biggest challenge faced in the promotion and application of 3D printing buildings is the lack of corresponding perfect standards. For this reason, the project team is the first to design a “frame + masonry + laminated panel structure” 3D printing building. meets current standards. The self-supporting walls and partial formwork of columns and beams are made using 3D printing technology, and the frame structure serves as the supporting structure. The successful design of this 3D printed building structure creates important conditions for the delivery and use of the project. .

Continuous Exploration of Shanghai Construction Engineering
Intelligent construction is one of the important directions for the development of my country’s construction industry during the “14th Five-Year Plan” period. Chen Xiaoming, chief engineer of Shanghai Construction Engineering Group, said: “On the path of exploring intelligent construction, large-scale 3D printing construction is the technical direction that Shanghai Construction Engineering Group prioritizes its development.
Over the years, Shanghai Construction Engineering has relied on a number of major national-level scientific research projects to carry out in-depth research and engineering practices on 3D printing processes, equipment and materials for materials polymers and high performance concrete materials.
“In 2019, Shanghai Construction Engineering’s first 3D printed bridge was completed in the central green space of Taopu, Putuo. It is also the first polymer material landscape bridge in China that uses 3D printing technology to be formed in one go. , “In the same year, in blessing In Quanzhou, Shanghai Construction Engineering also built a 3D printed pre-assembled segmented pedestrian landscape bridge, made of polymer materials. The bridge is 17.5 meters long, 3.2 meters wide wide and 3.2 meters high. 5 consecutive weeks to finish printing.

Last year, the “Liuyun Bridge” in Chengdu’s Yima River Municipal Park was also built by Shanghai Construction Engineering. It is the longest landscape bridge made of polymer material made using 3D printing technology. The main part is 21.58 meters long and 8 meters wide. , 2.68 meters high, with a net weight of 12 tons. When complete, the total length, including the approach bridge, is 66.8 meters. It innovatively adopts “segmented printing and prefabricated assembly technology”. a check-in point for internet celebrities.

Shanghai Construction Engineering has also used 3D printing technology to create “point of view” buildings that integrate with the environment in many domestic gardens and green spaces.

During the construction of a two-story building in Nanjing, Shanghai Construction Engineering’s experience with high-performance concrete 3D printing technology is an important manifestation of its continuous exploration of new architectural design and construction models.
3D printing has a wide range of applications in the construction of complex, custom, and personalized buildings and structures. It also offers broad application prospects in extreme construction environments such as reconstruction of disaster areas, nuclear power plants and lunar bases. This demonstration project explores a new construction method for modern houses, can realize large-scale construction industrial production, and will help the domestic construction industry improve the level of intelligent construction and lean construction.
