India’s first post office building constructed using 3D printing technology is set to be built in Bengaluru by Larsen and Toubro Limited. The construction project aims to design and build the 1,000 square feet Halasuru Post Office using 3D Concrete Printing Technology within 45 days.
According to L&T, the technology has been approved by the Building Materials and Technology Promotion Council (BMTPC), while the structural design of the post office has been validated by IIT Madras. The 3D printing of the post office building is cast ‘in situ’ at the job site in an ‘open to sky’ environment, using a fully automated 3D printer.
The cost of constructing the 3D printed post office is reported to be around Rs. 23 lakh, which is approximately 30-40% less than that needed to build a conventional post office, according to the New Indian Express.
L&T Construction’s focus for 3D printing technology includes various types of structures such as affordable housing, villas, military barracks, single-floor schools, post offices, and factories. The company is actively looking to expand its portfolio of 3D printed structures across different sectors, leveraging the benefits of this innovative technology.

The senior executive vice-president of L&T Construction MV Satish mentioned that the 3D printed structure is comparable to conventional structures in terms of durability, with a lifespan of 50 to 100 years.
Reacting to the news, Biotech giant Biocon’s executive chairperson Kiran Mazumdar-Shaw said, “Country’s first 3D-printed post office coming up in Bengaluru – hope this is the shape of things to come!!”
The post office project, which was proposed in August 2022, was supposed to be completed within a month. However, the execution was later delayed. L&T Construction is optimistic that the project will be completed within the stipulated 45 days.
India's first 3D printed post office is under construction at Halasuru, Bengaluru.
