![]() ![]() The details available to the printer include specifics of dimensions, and details whether a particular wall is load bearing and the thickness required. But instead of it being translated onto the ground by construction workers, a larger 3D printer takes a digital drawing to create a physical structure according to the scale finalised by the engineers. ![]() To build a 3D printed home is to begin at the basics of any construction plan: the blueprint. The company claims the materials as well as techniques used result in about a third of waste generated, compared with conventional construction. 3D printing can ensure that affordable, good quality housing is available to all Indians,” said Adithya VS, co-founder, Tvasta. “This technology can enable deep personalisation of construction. A 600-square foot, single-storey unit took three weeks to put together from printing to final construction, and the company said the cost was around ₹5.5 lakh, nearly a fifth of a typical 2-bedroom apartment in most parts of urban India. In April 2021, Union finance minister Nirmala Sitharaman inaugurated India’s first 3D printed home in Chennai (it is within the IIT-Madras campus), made by a tech start-up called Tvasta. ![]() Roughly five years later, in India and around the world, more people are beginning to understand what the prophecy meant. And if you 3D print it, they will come faster, cheaper and more sustainably,” Avi Reichental, CEO, chairman and co-founder of 3D printing company Nexa3D, said in 2018. Industry experts see 3D printing as the construction sector’s next big moment, and for a country like India, it holds a massive promise of affordable housing. Instead of four months in the above example, a 3D printed 2,000 square foot house can take as little as 7-10 days to erect. In other words, it is a far quicker way to create a structure – the build itself – than painstaking bricklaying and rebar reinforcement. Some essential supports and reinforcements can be prefabricated by the machine and incorporated into a house as it is being built. 3D printing in construction, also called 3DCP, makes use of robotics to deposit construction material in layers, creating walls, floors and roofs. The technology, in reality, has little to do with what the word printer typically evokes. Workers indulge in their work at the construction site of first-of-its-kind 3D printed post office building, in Bengaluru on April 11 (PTI) While it does not include the time taken to create the blueprints, or for power lines, windows and other finishing – it is still a long time, when compared to the newest building technology fast growing on the horizon: 3D printing. Typically, a 2,000 square foot home takes about four months to construct. ![]()
