L&T Builds India’s First 3D-Printed Post Office For Rs 23 Lakh

MV Satish, the senior executive vice president (buildings) at Larsen & Toubro, has confirmed to Moneycontrol that L&T is building India’s first 3D-printed post office for Rs 23 lakh in Bengaluru.

Two years after finance minister Nirmala Sitharaman inaugurated India’s first 3D-printed house at the Indian Institute of Technology Madras campus to boost affordable housing across the country, Larsen & Toubro is close to completing construction of India’s first public building in Bengaluru, using 3D-printing technology.

The building, a post office sprawled over 1,100 square feet, is being 3D-printed at a cost of Rs 23 lakh over 45 days. Although the technology cuts the construction time by 30-40 percent, the cost remains almost the same as for single projects, the company said.

“The technology has been approved by the Building Materials and Technology Promotion Council and the structural design has been approved by IIT Madras,” MV Satish, senior executive vice president (buildings) at Larsen & Toubro, told Moneycontrol.

3D printing construction ongoing.

Contrary to traditional construction methods, 3D-printing uses a robotic arm to create layers using a special concrete mixture fed into the system. The mixture has special adhesives for quick drying and other functions.

The system is controlled by an operator who feeds into the design and mainly controls the speed at which the mixture is funnelled out of the robotic arm according to the design plans.

The company announced in a securities filing late Tuesday that J&J will pay $9 billion to talcum powder cancer victims.
