Nanjing first batch
Concrete 3D printed carport
Only 2.5 hours
On-site installation and implementation in Jiangbei New District Research and Innovation Park
The second batch will be assembled within this week
This energy-saving, green and environmentally friendly carport
How is printing and splicing completed?
“Digital Intelligence” Empowerment
3D printing saves construction costs
Cement, fly ash, silica fume, admixtures, steel fibers… six or seven different raw materials are added to the cement mixer in sequence. Connected through pump pipes, the 3D printer head on the side uses this new type of concrete as “ink” to “draw” the carport components in circles according to the prescribed route .
In less than 3 hours, a carport component with smooth curved lines was printed. The production process is basically automated, with only a small number of start-up personnel and repair personnel, and labor costs are greatly reduced.
“The structure and shape of the carport are generated from computer drawings and CNC programs are realized through a 3D construction printer. No molds are required and the cost is low,” said the person in charge of the factory. “Using digital modeling, various shapes and patterns can be customized according to the needs of the application scenario. , color, size, rapid prototyping, effectively saving construction time .”
Reduce process
3D printing is easy to install on site
First installed concrete 3D printed carport
6 meters long and 2.2 meters wide
Composed of 6 arc-shaped components
The carport can be equipped with intelligent charging and fire-fighting facilities
Meet the needs for parking and charging of non-motorized vehicles
Compared with traditional construction methods, 3D printing eliminates the need for processes such as formwork erection, reinforcement, cast-in-place, and removal of formwork, avoiding dust and noise problems caused by on-site construction, and saving labor and time costs.
Turning waste into treasure
3D printing helps green environmental protection
The carport printing material innovatively uses ultra-high performance concrete, which has the advantages of high flexural strength, fire resistance, explosion resistance and impact resistance. It is understood that compared with the traditional parking shed’s light steel structure + tensile membrane, the new concrete has better flame retardant effect and a service life of about 40 years .
As the project progresses, the factory sorts and selects construction waste to ensure that the waste meets material conversion standards. Through a series of scientific treatment and fine processing, these waste building materials have been given new life and turned into high-quality materials suitable for 3D printing, realizing the resource utilization of construction waste .
Energy saving, environmental protection, no pollution
