China3D printingNet, January 18, in November 2019, a single-storey house was carried out.3D printingAfter that, Larsen & Toubro Construction (L&T), India’s largest construction company, has now completed the country’s first3D printingTwo-story building.The building area is only 65 square meters, using large-format concrete provided by OEM COBOD3D printingMachine manufacturing, composed of a local 3D printable concrete mixture developed by L&T’s internal team. The building is located in the company’s Kanchipuram factory near Chennai, and even integrates steel bars and fully complies with all building codes in India. MV Satish, Director of Construction and Senior Executive Vice President of L&T said: ” Concrete3D printingIs one of the technological disruptors, it is possible to fundamentally redefine the construction method, I am very happy to show that we are in3D printingWith regard to the ever-increasing expertise, we are in an advantageous position to break through the boundaries of automated robot construction. ”

Printing with actual concrete The fact that L&T uses its own real concrete mix to print buildings is an important milestone in itself.According to China3D printingThe net understands that so far, the vast majority3D printingThe buildings are built using ready-mixed mortar, which is relatively easy to print. The maximum particle size of ready-mixed mortar is 4 mm, which means that due to the lack of coarse additives, they are often weaker than traditional concrete, but the production cost is much higher. In addition, mortar usually does not comply with the building codes of most countries/regions, which limits the scalability of the material. What is impressive is that the L&T building is also equipped with vertical steel bars and horizontally welded mesh distributors, which took 106 hours of printing in total. Henrik Lund-Nielsen, founder and general manager of COBOD, added: “The L&T Construction project marks a big step forward for our industry on a global scale. The project not only shows that more and more traditional construction companies are adopting3D printingAnd real concrete made by L&T itself3D printingSignificantly because it helps to further reduce costs. How L&T developed 3D printable concrete and applied horizontal and vertical integral reinforcement in the building really left a deep impression. ”

Promote the construction of 60 million houses
India is currently working hard to build 60 million houses as part of a plan to achieve housing for all by 2022. L&T stated that it hopes the nearest3D printingThe building paves the way for further work and provides real housing for the citizens of the country. The company firmly believes that additive manufacturing will bring higher throughput while improving the quality of construction of new residential properties throughout the region.
