India is witnessing a transformative leap in the construction industry, driven by the rapid adoption of 3D printing technology. This innovation promises to not only accelerate building timelines but also contribute significantly to sustainable practices across the sector.
Chennai-based startup Kelvin6k has made a remarkable breakthrough, completing India’s first commercial onsite 3D printed buildings at the MES Tambaram military site. Using an indigenous SCARA robotic printer, these buildings – which include guard rooms and sentry posts – demonstrate the immense potential of 3D printing for construction, especially in remote and defence applications. The demand for 3D printing in construction is growing exponentially, particularly for projects in the defence sector, where speed and adaptability are key. Traditionally, constructing a 2,500-square-foot home would take about four months; with 3D printing, this timeline is slashed to just two weeks. Dr. Pradeepkumar Sundarraj, founder of Kelvin6k, noted the overwhelming demand, stating that the company is unable to keep up with orders. Their method uses locally sourced materials to construct buildings from scratch, including a pioneering zero-cement structure using geo-polymer mud.
This technological leap isn’t confined to defence alone. Architects are increasingly embracing 3D printing for residential and commercial projects, given its ability to create complex, custom designs that are difficult or impossible to achieve with traditional construction methods. Shashank Shekhar, CEO of MiCoB, a company that has worked on numerous defence-related projects, emphasised the sustainability benefits, pointing out that 3D printing reduces material wastage to near zero and can generate more efficient, environmentally friendly structures. The technology’s adoption in India gained national attention when the Ulsoor Bazaar Post Office in Karnataka became one of the first public buildings in the country to be constructed using 3D printing. This project, which would have taken six months with traditional methods, was completed in just 43 days.
Despite its promise, 3D printing is currently more expensive than conventional construction by around 10%. However, its long-term advantages—especially in terms of sustainability—are significant. Dhruv Gandhi, founder of Simpliforge Creations, a company known for designing the world’s first 3D printed temple in Telangana, highlighted the precision of 3D printing in material use, with negligible wastage compared to traditional methods. As 3D printing continues to make inroads into residential and affordable housing projects, its potential to address India’s housing shortage is immense. Sustainability is at the core of these innovations, offering the promise of reducing carbon footprints and revolutionising how we think about construction in the future. For the people of India, this technological advancement holds great promise not just for faster construction, but for a greener, more sustainable future. As demand for 3D printing grows, the vision of eco-friendly, cost-efficient housing that can be produced quickly and at scale is becoming a reality.
