Key Points:
- The British Virgin Islands government is collaborating with the Association of Reef Keepers (ARK) and Rethink Rebuild Regenerating "rrreefs" to revive coastal reefs using 3D printed structures.
- The first 3D printed reef in the BVI measures 20 cubic meters, consisting of 254 individual clay bricks produced in Switzerland and assembled at Cistern Rock off Cooper Island.
- This approach aims to combat coral reef destruction, with scientists estimating that up to 90% of reefs are at risk of being wiped out by 2050 due to climate change and human activity.
- The project is part of rrreefs' mission to revive 1% of coastal coral reefs globally by 2033 using advanced 3D printing technology and scientific design.
- Similar projects have shown promising results, with coral recruits observed just eight months after installation in San Andrés Island, Colombia.
BVI's Innovative Approach to Coral Reef Conservation
The British Virgin Islands (BVI) government has initiated a pioneering project to revive its coastal reefs using 3D printed structures. This initiative is a collaborative effort involving the Association of Reef Keepers (ARK) and Rethink Rebuild Regenerating “rrreefs”, an organization based in Zurich, Switzerland. The project aims to address the critical issue of coral reef destruction, which has been exacerbated by climate change, hurricanes, bleaching events, and human activities.
The BVI’s coral reefs, including the 18-mile-long Anegada Horseshoe Reef, one of the largest continuous coral reefs in the Caribbean, have been severely impacted. Since 2005, more than 90% of these reefs have been endangered. This situation mirrors the global trend, with NASA scientists estimating that up to 90% of coral reefs worldwide are at risk of being wiped out by 2050.
The Science Behind 3D Printed Coral Reefs
The 3D printed reef structures deployed in the BVI are not simply artificial replicas of natural coral. They are scientifically designed to create complex habitats that facilitate coral recruitment and provide homes for various marine species. The structures are printed using clay, a material chosen for its environmental compatibility and structural integrity.
The design process involves creating modular clay reef systems that can be seamlessly integrated into deteriorating reef areas. These structures are specifically engineered to rebuild areas that have lost their ability to protect shorelines from erosion. The complex habitats created by these 3D printed structures are conducive to coral recruitment and provide suitable environments for fish species, crustaceans, mollusks, and other macrofauna.
Dr. Shannon Gore, Managing Director for ARK, explains: “The design of these 3D printed bricks can be seamlessly integrated within deteriorating reefs to rebuild areas that are no longer able to protect shorelines from erosion.” This integration of artificial structures with natural reef systems is a key aspect of the project’s approach to reef restoration.
3D Coral Reefs Implementation and Monitoring
The first 3D printed reef structure deployed in the BVI measures 20 cubic meters and consists of 254 individual bricks. These bricks were produced in Switzerland and shipped to the Virgin Islands in late 2023. The structure was assembled on-site at Cistern Rock off Cooper Island, a location chosen for its popularity as a snorkeling and dive site and its proximity to ARK’s existing coral nursery.
Over the next two years, ARK will closely monitor the 3D printed reef to assess its impact on marine biodiversity. They will track coral recruitment, fish populations, and other marine life around the structure. This monitoring process is crucial for understanding the effectiveness of the 3D printed reefs and informing future deployments.
Ms. Argel Horton, a Marine Biologist and Environmental Officer at the BVI’s Ministry of Environment, Natural Resources and Climate Change, expresses optimism about the project’s potential: “Once it starts thriving, it can be replicated and integrated into our existing reef system so the Territory’s coastal defense can protect us from intense hurricanes, storms, and flooding in our critical low-lying communities.”
Implications for coral reef conservation efforts worldwide
The BVI project is part of a broader global initiative by rrreefs to revive 1% of coastal coral reefs by 2033. Similar projects have been implemented in other parts of the world, with promising results. In San Andrés Island, Colombia, where a similar structure was installed in 2021, the first coral recruits were observed just eight months after installation. The abundance and biodiversity around the artificial reef are now reported to be equal to that of natural reefs in the area.
The success of this project could have significant implications for coral reef conservation efforts worldwide. As Marie Griesmar, Co-Founder of rrreefs, states: “We look forward to seeing how this reef evolves over the coming years and how we can implement more of these types of reefs in the BVI.”

Frequently Asked Questions (FAQ)
3D printing creates complex structures that mimic natural coral habitats, providing a base for coral recruitment and a home for various marine species.
The reefs are printed using clay, which is environmentally compatible and provides the necessary structural integrity.
In a similar project in Colombia, the first coral recruits were observed just eight months after installation.
While currently focused on omena in Lake Victoria, the principles of rapid cooling and drying could potentially be adapted for other small fish species in different regions.
By reviving coral reefs, the project helps restore natural coastal defenses against storms and flooding, while also supporting marine biodiversity.
