This New Technology Can Build 350 SqFt House In A Week At Minimal Cost

3D printing is not a new concept, it has been used by engineers and designers since last 3 decades, but only recently have these versatile machines made its way in the public. With an increase in accessibility, more and more companies are resorting to it. This technology has revolutionized sectors like aerospace, medicine and automobiles, the new addition to the list is construction. It plays a very important role in the construction sector because of its easier creation of prototypes, molds, and solid objects with the possibility of correction at the last minute.

In a country like India, where millions live in make-shift shacks made up of metal and wood with dirt floors, constantly exposed to rain and heat. 3D printing construction technology is a god-sent for them. The students and faculty members of IIT- Madras has come up with India's first 3D printing Construction technology in order to make homes quicker and cheaper for the have-nots. They claim to be able to build a house of 350 square feet in less than a week, at a cost cheaper than conventional methods.

“Usually, a concrete layer will take minimum 28 days to 30 days for curing. But, in our innovative technology, the concrete will set in 3 to 5 hours,” said Vidyashankar C, one of the co-founders of Tvasta Manufacturing Solutions to Deccan Chronicle. Tvasta Manufacturing Solutions, an additive manufacturing start-up founded by the team of four IIT - Madras students - Adithya VS, Parivarthan Reddy, Vidyashankar C and Santhosh Kumar- has developed the technology along with IIT Madras faculty members.

It took them 3 years to develop the 3D printing construction technology and 3D printer. “3D printing of concrete gives a new dimension to construction. This technology can best meet the complex demands of modern architecture with concrete,” says Prof Manu Santhanam, department of civil engineering, IIT Madras. The start-up aspires to completely automate construction work including placement of reinforcements and finishing, by re-envisioning the construction process

According to them automation and computerization of construction and development will not only bring greater efficiency and precision to the work but will also be more safe. Adding to that it will also get the required work done in lesser time with the use of fewer resources. “Due to the reduction of time in house building and less requirement of labourers, the building cost would come down. The operation of printers also would create skilled labourers,” says Vidyashankar to DC.

Though the cost and the construction time would cut down drastically, but it doesn't mean it will be less safe, even in that aspect the durability of the building would be greater than the conventional ones.

Having said that, they still have a long way to go. At present, they have come up with a proto-type 10 X 10-metre 3D printer. Soon the team hopes to come up with a bigger printer to enable it to build a house. “We will be building India's first 3D printed house within the next one year. The impact of 3D printing in construction will be mainly be brought into use for “Housing for All” scheme,” says Adhithya VS while talking to Deccan Chronicle.

Technology though always welcomed, one needs to keep in mind the feasibility of it. According Reuters, almost 40 million Indian population work at construction sites. India that is already struggling to feed its poor, is it ready for more jobless people? Think about it and let us know in the comment section
