L&T Construction, a subsidiary of Larsen & Toubro, recently announced that it has built a multistory building using 3D printing technology. The building is said to be the first of its kind in the country and proves that 3D printing technology can be used for construction purposes as well.

The printed two-story building, covering a 700 square foot area, is located at the Kanchipuram plant of Larsen & Tourbo. It uses a special concrete mix along with traditional construction materials. Welded mesh was also used along with vertical iron reinforcement bars to satisfy the Indian codes of construction and make the building cost-effective. A fully automated 3D printer was employed for the construction work, which took 106 hours to print. The building was built ‘in situ’ by placement of one 3D printed layer over another.

3D printing is a technology used by printers to construct a three-dimensional object by printing layer upon layer. The construction vertical of 3D printing technology is still under research around the world. The 3D printed housing model builds hope for fast and affordable housing in the country.

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
