India’s first 3D-printed post office is slated to come up in Bengaluru, Karnataka and will cost around one-fourth of the amount spent on a traditional building. The new post office building in Cambridge Layout in Halasuru, Bengaluru will be built using 3D printing and is likely to be completed within the next month. The Post Office building is being constructed by Larsen & Toubro, which is the only company currently in India utilising 3D printing technology for construction.

3D printing can significantly reduce the cost and expedite construction which would otherwise take months to complete. 3D printing of the new post office which will be a three-storied building has been given clearance by the Building Materials and Technology Promotion Council of the Ministry of Housing and Urban Affairs and IIT-Madras.
India’s first 3D-printed building:
- In December 2020, L&T had successfully 3D-printed a 700 sq feet building (ground plus first floor) with reinforcement, for the first time in India.
- Using a fully automated 3D printer, L&T 3D printed the building at their facility in Kanchipuram, Tamil Nadu with a special, in-house developed concrete mix, using indigenously available regular construction materials.
- The building was printed with both vertical reinforcement bar and horizontal distributors using a welded mesh that satisfies provisions in the Indian Codes and optimises the cost of construction.
