In the construction industry, 3D printing technology conforms to the development of the industrial revolution, will enable large-scale personalized production, gradually realize rapid construction and industrialized production, and will create a large number of new materials that cannot be produced by traditional processes, which will Bringing major changes in the global manufacturing economy.
1. In March 2017, Apis Cor, a 3D printing expert with offices in Russia and San Francisco, announced that they produced a 3D printed house within 24 hours. This means that from the time of drinking coffee yesterday to the time you sat down to eat cereal this morning, they have made self-supporting walls and partitions for the entire house, and installed and added roof and interior decorations on site. The house is located in a Russian town called Stupino. It uses Apis Cor printers to print on site, which means that the logistics cost of transporting parts and building materials from the factory to the home will be almost completely eliminated.
Imagine that if you have already chosen the address of the house to be built, Apis Cor only needs to set up a 4.5-meter printer on the site, which can print the house in one day. Compare it to the traditional construction time of six to seven months, and you will be attracted by its potential advantages.
2. An area of 640 square meters, a height of about 9.5 meters, a double-layer, white conjoined structure... The office building of Dubai City Government, Dubai, which was completed not long ago, is currently the world's largest 3D printed building. It is understood that during the construction of the building, there were no building materials piled up around the site. Workers use traditional construction methods to build foundations, and then use large spreaders to move 3D printers to various fixed points of the building. The 3D printer directly outputs the building materials on the pre-set building outline, and the layers are stacked up to the required height. After the walls were printed, the workers were reinforced with cement and concrete and installed windows.
The cost of the building is less than AED 1 million (1 AED is about 1.92 RMB), and it is estimated that AED 2.5 million will be required to build using traditional methods. The construction waste generated by it is also reduced by about 60% compared with traditional buildings. Helen Lumpis, R&D manager of Swiss building materials company Lafarge Holchem, believes that 3D printed buildings are not only low-cost but also easy to replicate, and can meet large-scale housing needs in the future.
3.3D printing a Chinese courtyard in Shanghai, with three bedrooms and two halls in one house is the perfect work of cutting-edge 3D printing construction technology. Such a project, if it takes at least one year to be produced by traditional craftsmen, but 3D printing is only spent In a week, this is also the world's first 3D printed Chinese garden.
Compared with the traditional construction method, the 3D printing construction site only needs three to five workers, a printer, a crane, an excavator, and the 4,000 square meter building can be completed in only 7 to 10 days, which is the original traditional industry. 50% to 70% of the cost. At the same time as efficient construction, Ma Yihe has always adhered to the research and development concepts of green, environmental protection, energy saving and material saving. Using new materials developed by the construction of tailings and solid waste steel slag for house printing has greatly saved costs and realized Environmental protection concept of taking materials locally and recycling construction waste.
