According to recent news reports, a 3D-printed post office is being built in Bengaluru, India, which will be the first of its kind in the country. Residents of Cambridge Layout are reportedly pleased with this development. The cost of constructing this post office is estimated to be 30 to 40 percent lower than that of a traditional building, and it is expected to be completed within 30 days. The 1100 square feet post office will cost around Rs 23 lakh to construct.
The use of 3D printing technology can significantly reduce construction costs and expedite the building process, which would otherwise take several months. The proposed three-storied post office in Bengaluru has received clearance from the Building Materials and Technology Promotion Council of the Ministry of Housing and Urban Affairs and IIT-Madras for its 3D printing. This will be India’s first 3D-printed post office building.
In December 2020, L&T successfully constructed a 700 square feet building with reinforcement, using 3D printing technology for the first time in India. L&T used an in-house developed concrete mix made from regular construction materials that were readily available in India, and a fully automated 3D printer for the construction at their facility in Kanchipuram, Tamil Nadu. The building was printed with both vertical reinforcement bars and horizontal distributors using welded mesh, which meets the provisions of Indian codes and helps optimize the cost of construction.
