India’s First 3D-Printed Artificial Reefs:
Tamil Nadu is set to deploy India’s first 3D-printed artificial reef modules under the second phase of the Pradhan Mantri Matsya Sampada Yojana to support marine habitat restoration.
- The pilot deployment is scheduled off the Ramanathapuram coast and will test six newly developed reef designs in coastal waters.
Scientists will assess the durability and ecological performance of the modules under local coastal conditions before considering larger-scale deployment. - The project is being carried out in collaboration with the Visakhapatnam Regional Centre of ICAR-Central Marine Fisheries Research Institute. Each module weighs about 1 tonne and has been developed by Chennai-based startup Tvasta, an IIT Madras-incubated company.
- Unlike conventional reinforced concrete reefs, these modules are made without iron reinforcement and have complex 3D-printed structures with crevices, folds and attachment surfaces.
- The design aims to increase porosity, surface area and habitat suitability for corals, sponges and other reef-associated marine organisms.
- The initiative, funded jointly by the Centre and State in a 60:40 ratio, is part of a wider artificial reef project across 213 sites in Tamil Nadu and is expected to benefit traditional fishing communities through improved fish stocks and healthier marine ecosystems.
