Chennai-based deep-tech startup Kelvin6K just made waves on Shark Tank India 5, securing a massive deal for their robotic 3D-printing tech.

Founders Dr. Pradeepkumar and Dr. Ravi Kant shared a bold dream: "By 2030, our target is to 3D print on the Moon and Mars."

This mobile robotic arm can 3D print structures on-site. It’s flexible, precise, and eliminates the need for traditional, labor-intensive methods.

Kelvin6K can print a 2,500 sq. ft. home in under a month—reducing construction timelines by 60% and costs by 30%.

Using a fly ash-based geopolymer "ink," they’ve achieved a 90% reduction in carbon emissions compared to traditional cement.

FY 23-24: ₹30 Lakhs FY 24-25: ₹72 Lakhs FY 25-26 (Projected): ₹2.5 Crores

While others stayed back, Ritesh Agarwal offered ₹1 Crore for 2.86% equity + 2.14% advisory equity to scale this infrastructure revolution.
