The structural design of the post office has been validated by IIT Madras
India's first 3D-printed post office has come up at Cambridge Layout, Bengaluru. The post office was inaugurated by Union Communications Minister Ashwini Vaishnaw on Friday (August 18, 2023). Later, he also shared a video explaining the technique used in the building's construction.
Prime Minister Narendra Modi hailed the development and described the post office building as a testament to India's innovation and progress.
"Every Indian would be proud to see India's first 3D printed Post Office at Cambridge Layout, Bengaluru. A testament to our nation's innovation and progress, it also embodies the spirit of a self-reliant India. Compliments to those who have worked hard in ensuring the Post Office's completion," Prime Minister Narendra Modi tweeted.
L&T Construction designed and finished the 1,000 square feet Halasuru Post Office using this innovative technology within a tight timeframe of 45 days.
According L&T Construction, while the technology has been approved by the Building Materials and Technology Promotion Council (BMTPC), the structural design of the post office has been validated by IIT Madras. The 3D printing of the post office building was cast in Situ’ at the job site in an ‘open to sky’ environment, using a fully automated 3D printer.
A press release issued by the company in April 2023 had described 3D concrete printing as an emerging technology that has the potential to transform construction practices by quickening the construction process and enhancing overall build quality. Using a robotic printer, 3D printing technology deposits concrete layer-by-layer in accordance with the 3D model drawing input.
The process requires a delicate balance of concrete properties, including flowability, quick hardening for load-bearing capacity, green concrete status for inter-layer bonding, and sufficient strength to ensure successful printing, the press release explained.
In construction using 3D printing, the material is printed under computer control to build a 3- dimensional product. A robotic arm is used to spread this concrete mixture, which has special adhesives for rapid drying, layer by layer.
In 2021, Union Finance Minister Nirmala Sitharaman had inaugurated India's first 3D printed house. Constructed on the campus of IIT Madras, it was developed by Tvasta Manufacturing Solutions.
A year later, in December 2022, the Indian Army completed construction of its first 3D printed House Dwelling Unit for solders. Constructed in 13 weeks time using the latest 3D Rapid Construction Technology, the building is earthquake resilient and follows green building norms.
