L&T Construction completes India’s first 3D printed building

DUBAI, January 17, 2021

India's top engineering conglomerate Larsen & Toubro (L&T) said one of its units, L&T Construction has 3D printed the country's first two-storeyed building using concrete mix developed by its inhouse team. This is its second building made with printer supplied by Cobod, a leading global developer of modular 3D construction printers.
 
A $21 billion technology, engineering & construction conglomera, L&T is ranked among the world's top 30 contractors. 
 
The two storeyed building (G+1) of 65 sq m was completed using 3D printable concrete mix developed by their inhouse team, based on locally available raw materials and methods for integrating reinforcement with the 3D printed concrete in an open to sky environment.
 
The 3D printing was successfully completed by using a printer supplied by Cobod and with the support of Cobod. 
 
The new building, which is located close to Chennai in the southern state of Tamil Nadu, is the second facility L&T has made with the Cobod printer, the first being a one floor 22 sq m building with a bedroom, hall and kitchen. 
 
V Satish, L&T director & senior executive vice president (buildings) said: “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.”
 
The printing made by L&T marks an important new milestone, where a conventional type real concrete has been printed by a conventional construction company now having adopted the 3D printing technology, believed to be the future of construction.
 
Henrik Lund-Nielsen, the founder and general manager of Cobod, said: “L&T Construction’s project marks a huge step forward for our industry, on a global scale."
 
"Not only is the project showing that more and more conventional construction companies are adapting 3D printing, but the 3D printing of a real concrete made by L&T themselves is significant, as this helps to drive down the cost even further. It is really impressive how L&T developed the 3D printable concrete and applied integral horizontal and vertical reinforcement in the building,” he added.-TradeArabia News Service
