CHENNAI: The now labor-intensive construction industry could undergo a sea change with the adoption of 3D printing. Engineering giant Larsen & Toubro (L&T) recently built a ground-plus-three-storey (1,700 square foot) building in just 106 hours using this technology in a bid to attract developers to the town.

The fully automated construction method uses a robotic printer to print/lay down layers of concrete without any formwork to construct a building according to a 3D model drawing. Although the cost may remain the same, there will be time and resource benefits. “Any building takes about 100 days to complete. With this technology, we can complete it in 30 days,” says MV Satish, Full-Time Director and Senior Executive Vice President (Buildings), L&T.

The technology has been approved by the Building Materials and Technology Promotion Council (BMTPC) while the design has been approved by IIT Madras. But, the clearance is for the moment only for the ground floor plus three floors. Now work is underway to finalize an Indian Standard (IS) code so that certain standards are in place to adopt the technology on a large scale. The codes are used by civil engineers in India for the design and analysis of civil engineering structures such as buildings, dams, roads, railways and airports.

L&T believes the new construction method is better than traditional methods. It can provide sound and thermal insulation that traditional buildings generally lack. It could also be used for troops stationed in extreme climates. “We can use the technology to build barracks for soldiers in places like Leh, schools, post offices, etc. across the country,” Satish said.

Through a model apartment in Ramapuram, L&T is courting developers in Chennai who want to build villas (ground floor plus 1 or land plus 2). “Some people have shown interest and we’re confident we’ll get orders,” Satish said.

The success of 3D printing lies in the knowledge and mastery of 3M – material, machine and methods – for a rapid and successful large-scale construction. Additionally, concrete 3D printing must address the challenge of printing in an open environment by controlling variables such as ambient temperature, humidity, humidity, dust, and others that can affect properties. concrete. The machines, which are imported from the Netherlands, are expensive. Satish hopes prices will drop as the technology gains acceptance.
