Information
Now many technical colleges have 3D printing majors, but many people think that there are few jobs. This is not the case. In order to understand the application of 3D printing in the future, on the afternoon of July 6, 2016, the reporter of professional magazine came to Tongzhou District, Beijing, and visited the first villa printed out on site in the whole country.
In front of the reporter is a two-story villa of 400 square meters. At present, the existing 3D printing buildings are part of the structure of the house printed in advance, and then spliced. But the difference of this printing is that the four walls are directly printed on the construction site through 3D printer, which is "overall printing".
The device used to print this villa is 6 meters wide and 20 meters long, which can be moved. The printer prints out 10 cm walls at a time. After finishing a circle, it will return to print the next 10 cm wall. The whole process is automatic operation. Every floor it prints, in addition to the walls around the villa, the walls that separate each room will also be printed. In the position where the window needs to be replaced, the system will automatically stop spraying concrete, and continue to pour automatically when it bypasses the window.
According to the person in charge of Beijing Chinese businessman Tengda Industry and Trade Co., Ltd., who completed the initiative at this stage, the printing equipment can be designed differently according to the requirements of the building complex, and most of them can be realized.
Wu Jianping, head of Beijing Huashang Tengda Industry and Trade Co., Ltd., said that it would take about 3-6 months to build a two-story building with equal area with traditional building methods. The villa printed by 3D printer basically took 45 days. The labor cost of building such a villa by the traditional construction method is about 50% of the total cost of the building, but the 3D printing technology directly casts and forms, cancels the formwork construction, and greatly reduces the project cost.
The first step is electronic batching; the second step is to mix the prepared raw materials and mix the volume of concrete; the third step is to transport the mixed materials to the printer; the last step is to print and fix the consistent steel structure at the same time, the two tracks of the printer are respectively placed in the double steel structure and frame the overall scope of the whole building. Then, as long as the building drawing data is input into the printer's CNC system, the system will automatically intervene the printing nozzle, and pour concrete on the reinforcement according to the wall direction.
"In the process of overall printing on site, the biggest problem is how to overcome the problem of rapid solidification," Wu said In this printing process, after the ordinary concrete is mixed, the wall is difficult to form because it can't solidify quickly. After his guidance of the research team, he made continuous innovation, and finally made a technical breakthrough, realizing the solidification and forming within 3-5 minutes. Another problem is that due to the limited cost of the company, there is no way to carry out the test on the test bench, but according to the national requirements for building design, it is enough to build a two-story building with the same area and can resist the magnitude 8 earthquake intensity, with 5 tons of steel bars. But in order to ensure the quality, the thickness of the villa wall is 25cm, the foundation and wall are reinforced by 20t, and the concrete is all standard C30. "
Wu Jianping, the person in charge, told reporters that 3D printing technology is the trend of social development. At present, the high-intensity construction of the society has greatly wasted human and material resources, and it still needs to face a long time waiting for the house to be reinforced. It is gratifying to note that the on-site construction team for 3D overall printing villa only needs 5-6 technicians, which may be reduced in the future. In this way, the construction workers can be freed from the heavy work.
Society's demand for 3D printing technicians will be growing. Because 3D printing technology has a wide range of applications, from sitting chairs to human organs, from delicate space equipment to spacious houses, there have been cases of 3D printing technology. Wu Jianping also pointed out that the current "3D printing" specialty is not "professional". In the future, 3D printing technology teaching, a major is definitely not good, there should be many majors. In this way, 3D printing technology can be refined into different industries, and relevant talents will be responsible for different projects. However, we should pay special attention to the fact that the 3D printing major established in the technical colleges at this stage still needs to be improved, and the training of classified technical talents needs to be further refined, so as to better serve the society. When talking about the next development plan, Wu Jianping said, "the company will continue to make efforts, so that the team can develop better products and benefit the people. At the same time, he also hopes that products printed using the overall 3D technology can be popularized in China."
