Built in 43 days: India’s first 3D-printed post office inaugurated in Bengaluru-

Union
Minister for Railways, Communications, Electronics and IT Ashwini
Vaishnaw on Friday dedicated to the nation India’s first 3D-printed post
office located in Bengaluru’s Cambridge Layout.
The
post office, which was virtually inaugurated by the Union minister from
the General Post Office building, was completed in just 43 days – two
days ahead of its deadline. Its construction was carried out by Larsen
& Toubro Limited with technological support from IIT Madras under
the guidance of Professor Manu Santhanam, Building Technology and
Construction Management Division, Department of Civil Engineering.
“Bengaluru
always presents a new picture of India. The new picture that you saw
today in terms of this 3D-printed post office building, that’s the
spirit of India today. That’s the spirit with which our country is
progressing today,” minister Vaishnaw said.
The
post office covers a built-up area of 1,021 sq ft. Its construction was
carried out using 3D concrete printing technology which is a fully
automated building construction technology wherein a robotic printer
deposits the concrete layer by layer as per the approved design, and
special grade concrete – which hardens quickly – is used to ensure
bonding between the layers for the purpose of printing the structure.
George Abraham, head of operations (south and east), L&T, explained,
“It is because of the robotic intervention that involves pre-embedded
designs, that we were able to complete the entire construction activity
in a period of 43 days as compared to about 6-8 months taken by
conventional method.”
