Kelvin6k, the creator of ‘the world’s most affordable construction 3D printer’, is revolutionizing the construction industry with its cutting-edge robotic and sustainable construction solutions. The company’s crowning achievement to date is the construction of India’s first onsite 3D printed building – using a “Made in India” 3D printer – a 300 square foot office that was erected in just ten days using their proprietary construction technology.

Developed in-house within a remarkably short span of four months, the company’s 3D printing robots are not only custom-built and technologically advanced, but also affordable – with the Indian market specifically in mind. The robustness, simplicity, and affordability of Kelvin6k’s machines have stirred international interest, making the company competitive in the global market.

Currently, Kelvin6k is one of the only Indian firms capable of manufacturing large-scale onsite concrete 3D printers. With the initial financial support of $125,000 from Ondeck, the company’s printers significantly undercut international competitors – costing just a fraction of their global counterparts. This affordability has sparked demand from both local and foreign buyers, especially from the US, Dubai, and Canada.

Kelvin6k’s ambitious vision for the next 2-3 years is to lead the global construction 3D printing market by providing affordable solutions worldwide. The company aims to automate processes like foundation laying, reinforcing concrete, plastering, and painting – addressing the growing need for quick and affordable housing solutions in the face of India’s escalating urban housing crisis.

Dr. Pradeepkumar Sundarraj, CEO and founder of Kelvin6k, believes that “everything that can be automated must be automated.” With a name inspired by the sun’s surface temperature (6000 Kelvin), the startup reflects his enthusiasm for solar energy.

The company’s concrete 3D printing technology has drawn global attention for its onsite printing capability, a first for an Indian company. The printers offer a cost-effective alternative to importing pricey technology – helping to reshape the narrative of technology transfer.

The growth of innovative Indian startups like Kelvin6k is turning the tables on the traditional technology adoption cycle – where India typically receives technologies after they’ve run their course in Western countries. Kelvin6k, instead, is ready to export superior technology. Dr. Sundarraj and his co-founder, Dr. Ravi Kant Upadhyay, believe in the vast potential of their field – foreseeing a significant expansion of the current construction market. They’re reportedly committed to educating people about concrete 3D printing and its benefits – advocating for its adoption as an efficient technology that can transform house construction from a months-long process into a matter of days.
