Larsen & Toubro Construction (LNTECC), the Indian technology, engineering, construction, manufacturing and financial services conglomerate, recently constructed India’s first 3D printed building. The building was constructed at its Kanchipuram facility.
The ground plus one-floor structure occupies 700 square feet built-up area. L&T developed a special concrete mix using indigenously available regular construction materials as the material for 3D printing.
India’s First 3D Printed Building
The building was constructed at the job site and was completely 3D printed except for the horizontal slab members. According to the L&T officials, the 3D printing took close to 106 hours using a construction 3D printer.
According to M V Satish, Whole Time Director & Senior Executive Vice President (Buildings), “3D concrete printing is one of the technology disruptors with the potential to radically redefine construction methodologies and I am extremely happy that by demonstrating our growing expertise in 3D printing, we are well-positioned to push the boundaries of automated robotic construction,” said M V Satish, Whole Time Director & Senior Executive Vice President (Buildings).
Satish added, “3D printing will not only accelerate the pace of construction but also significantly improve build quality.”
This achievement will certainly give a huge fillip for the mass housing segment, with the objective of creating 60 million houses under the Housing for All by 2022 programme, Guidance, Tamil Nadu tweeted that the technology is the ‘future of Sustainable Construction’. Technology developers said the use of technology depends on how much it would cost to build a building.
This building follows an earlier structure built in November 2019. The team had 3D printed a 240 square feet 1 BHK building, in line with typical economic weaker section building layout, to explore the feasibility of this innovative technology. The building was printed with both vertical reinforcement bars and horizontal distributors using a welded mesh that satisfy provisions in the Indian Codes and optimise the cost of construction.
