India’s first 3D printed house at IIT-Madras

It’s a small house measuring 600 square feet on the campus of IIT Madras. But the significance of this small house can be gauged from the fact that it was inaugurated (virtually) by none other than our Finance Minister Ms Nirmala Sitaraman. Its the country’s first 3D printed house built in just five days.

Chennai based TVASTA Manufacturing Solutions built it on a concept by IIT Madras 2016 batch alumni Adithya Jain, C Vidyashankar & Parivarthan Reddy. [email protected], a startup founded by IIT Madras alumni, is a part of the new incubator of the Ministry of Housing and Urban Affairs established at IIT Madras. “This advancement will open doors for all kinds of research and development in the construction world,” says Tvasta.

“Tvasta’s approach with concrete 3D printing and its applications has evolved over the years, leading to perfect execution of the models. Ranging from mesh walls, to stairway decor, we can help you reimagine your ideas in a limitless manner.”

The technique utilises a concrete 3D printer that accepts a computerised three-dimensional design file from the user and fabricates a 3D structure in a layer-by-layer. The cost is 20-30 per cent cheaper than conventional construction.

It may be recalled here that last year the infrastructure major Larsen and Toubro (L&T) had built a two storeyed house with the Tvasta Manufacturing Solutions in Kancheepuram. The 3D printed building, which has a built up area of 700-sq.ft and is located at L&T Construction’s Kanchipuram facility, has been built with a special, in-house developed concrete mix using indigenously available regular construction materials. The building was printed with both vertical reinforcement bars and horizontal distributors using welded mesh, that satisfy provisions in the Indian Codes and optimise the cost of construction. Barring the horizontal slab members, the entire building structure was 3D printed ‘Cast in Situ’ at the job site in an ‘open to sky’ environment within 106 printing hours, using a fully automated 3D printer.
