L&T Construction, the construction arm of the $21 billion technology, engineering & construction conglomerate, Larsen & Toubro, has 3D printed a G+1 (Ground plus one) building with reinforcement for the first time in India.

With the country aggressively pursuing the objective of creating 60 million houses under the Housing for All by 2022 programme, this achievement will certainly give a huge fillip to the mass housing segment, said the company.

“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).

He added, 3D printing will not only accelerate the pace of construction, but also significantly improve build quality.He added, 3D printing will not only accelerate the pace of construction, but also significantly improve build quality.The 3D printed building, which has a built up area of 700 sq.

feet and is located at L&T Construction’s Kanchipuram facility, has been built with a special, in-house developed concrete mix using indigenously available regular construction materials. The building was printed with both vertical reinforcement bars and horizontal distributors using welded mesh, that satisfy provisions in the Indian Codes and optimise the cost of construction.
