India’s First 3D-Printed Building With Indigenous Construction Materials

According to construction major L&T Construction, it has 3D-printed successfully a 700-square-feet building. It is said to be the first one in India.

To print the house, L&T used a fully automated 3D printer at their Kanchipuram facility with its in-house concrete mix made using indigenous regular construction materials.

L&T printed the building with both horizontal distributors and vertical reinforcement bar using welded mesh meeting the provisions provided in the Indian Codes while optimizing the constructing cost.

Apart from the horizontal slam members, the company said that it 3D-printed the entire building at the job site and in an “open to sky” environment in 106 printing hours.

L&T’s Senior Executive Vice President and Whole Time Director, M. V. Satish, said that he was extremely happy that the company could demonstrate its expertise in 3D printing. The company has the ability to push automated robotic construction’s boundaries.

3D printing will surely improve build quality significantly as well as accelerating the pace of construction.

The achievement of L&T is important as India is trying to reach the objective of the Housing for All by 2022 program, building 60 million houses.

In 3D-printing, using computer control, people print the material to build a 3D product, layer by layer. It is mostly used in manufacturing industries for prototypes, small batch production, and complex shape printing.

Back in November 2019, the team at L&T built a 240-square-free building with 3D-printing.
