India’s first 3D printed house
Three IIT Madras alumni in 2016 founded a deep tech startup named. This company has now built the first 3D printed house in India. The single storey house is equipped with all modern amenities, a single bedroom, a kitchen and a hall. It has a built-up area of approximately 600 square feet.

Printing the whole process took around 21 days due to restrictions related to Covid 19. The company is able to print such structures in around 5 days.
Adithya VS, who is the CEO of Tvasta Manufacturing Solutions while speaking to The Better India, said that “Tvasta’s 3D printing technology is designed to bring digital technological advantages to the construction industry. The goal is to make the process accessible to all sections of the construction industry, including affordable housing and large-scale infrastructure construction. Reducing the overall time required for construction involves an order of magnitude change. What would take months to build can be built in days. “
He added that, “Currently the capacity is to print the superstructure of a house that would take 4-5 months to build conventionally in about 5 days. The technology has also been designed to be sustainable and green. The material used contains industrial waste and recycled materials. This reduces the overall carbon footprint of the structure during construction. “
The house was developed in collaboration with the Terwillinger Center for Innovation in Shelter from Habitat for Humanity. The main objective of building this structure was to showcase the research, development and manufacturing capabilities available in India.
Concrete 3D Printing technology offers many advantages such as reduction of construction cost, reduction of carbon footprint, use of environmentally friendly materials and many more.
Houses built using 3D printing technology can be customized according to the geographic and climatic conditions specific to a particular area. For this reason, additional costs such as cooling are reduced. It also helps reduce the overall energy consumption of the house.
While talking about the benefits of concrete 3D printing, Adithya VS said, “The cost reduction is achieved by increasing the productivity of the workers involved in the construction process. A structure that would take months to build can be completed in a few days; this contributes to huge savings on time and cost of capital. “
He also added: “There is also a saving on the amount of material used because 3D printing reduces the waste and the total amount of material needed to build a structure. The time saving is mainly due to the use of robotics and automation technologies. “
The material used for the construction of this structure is a proprietary 3D printable mixture which was developed by the company. Apart from this, natural materials such as mud can also be used for construction. In the future, according to Adithya, the company aims to introduce green materials in the construction industry.
Concrete 3D Printing technology is an automated manufacturing method of Tvasta Manufacturing Solutions. The technology is developed completely locally. The structure is intended to be used as a conference center at IIT Madras.
