World’s Largest 3-D Printed Reef Installed at Summer Island Maldives
The world’s largest 3-D printed reef was submerged at Summer Island Maldives this summer, in what is hoped could be a new technology-driven method to help coral reefs survive a warming climate. The artificial reef, assembled with hundreds of ceramic and concrete modules, was submerged at Summer Island’s ‘Blue Lagoon’ – a sandy part of the lagoon, where the resort hopes to create a new coral reef ecosystem.
The project started in a lab in Melbourne, Australia, where industrial designer Alex Goad of Reef Design Lab used sophisticated computing modeling to design reef structures similar to the coral reefs found naturally in the Maldives. A large 3-D printer whirred away for 24 hours to print moulds of the reef structures. These moulds were cast in ceramic – an inert substance, similar to the calcium carbonate found in coral reefs. The ceramic moulds were shipped to the Maldives, and filled with marine concrete on the beach at Summer Island. 220 ceramic, concrete filled moulds were then slotted together, like a giant LEGO set, to create
the new reef.
The new reef sits in seven metres of water, close to the resort’s existing coral nursery. Fragments of coral from the nursery are being transplanted onto the 3-D reef, where they will grow and colonise the structure. As Alex explains: “3-D printing technology helps us to develop more innovative ways of protecting coral reefs. The technology allows us to mimic the complexity of natural reef structures, so we can design artificial reefs that closely resemble those found in nature. We hope this will be a more
effective way of growing and restoring corals.”
In a year or two, when the corals have grown over the 3-D reef, the resort hopes to have a new, natural looking reef, teeming with fish and marine life. If the 3-D printing technology proves more successful at growing corals than existing coral propagation methods, it could be a novel way of helping coral reefs survive a warming climate.
The Maldives is one of the world’s most climate-vulnerable nations. Rising sea temperatures pose a grave threat to the world’s coral reefs, and mass bleaching events are becoming more common and more severe. Summer Island Maldives has implemented a number of recent environmental initiatives, including the adoption of solar energy, a ban on the use of plastic straws, phasing out imported drinking water, and coral conservation projects.
Summer Island Resort Manager Mari Shareef explains: “Projects like the 3-D printed reef are popular among guests, who like that we protect our environment. And it’s not only for the guests. Our staff, most of whom are Maldivian, want to protect their environment too. Ultimately, we want to help promote a culture of environmental stewardship, not just at Summer Island, but across the Maldives.”

Renowned anti-whaling activist Paul Watson has been released from custody in Greenland after spending five months in detention. Denmark’s Justice Ministry rejected Japan’s request for his extradition, citing insufficient guarantees that his time already served in custody would be credited against any potential sentence.
The 74-year-old Canadian-American was arrested on July 21 in Nuuk, Greenland’s capital, when his ship docked to refuel. His arrest was based on a 2012 Japanese warrant related to a 2010 encounter in Antarctic waters. Japan alleged Watson obstructed operations and caused damage to a whaling research ship during efforts to disrupt illegal whaling. Watson has consistently denied these claims, maintaining his commitment to marine conservation.
Denmark, which oversees extradition matters for Greenland, concluded that while the legal conditions for extradition were met, the lack of assurances from Japan regarding time-served credit made extradition untenable.
In a video shared by his foundation, Watson expressed gratitude and relief, saying, “After five months, it’s good to be out… and good to know they’re not sending me to Japan.” He added that the most difficult part of his time in custody was being separated from his two young sons.
Watson is a pioneering figure in marine conservation, known for founding the Captain Paul Watson Foundation in 2022 after decades of activism with the Sea Shepherd Conservation Society. His bold efforts to defend marine life have earned him widespread support, including from celebrities and conservationists. His work has also been featured in the acclaimed reality TV series Whale Wars.
Watson’s lawyer, Jonas Christoffersen, praised the decision, stating, “We are happy and relieved that Paul Watson is now free.” He added that Watson is eager to reunite with his family and continue his vital work.
The arrest occurred while Watson’s vessel, the M/Y John Paul DeJoria, was en route to the North Pacific with a team of 26 volunteers to intercept a Japanese whaling ship. His foundation described the arrest as politically motivated and emphasized that Watson’s actions were focused on ending illegal whaling practices.
Japan resumed commercial whaling in 2019 after leaving the International Whaling Commission, asserting that whale meat is a cultural tradition. Conservationists, however, continue to challenge these practices, highlighting their impact on marine ecosystems.
Despite the challenges, Watson remains steadfast in his mission to protect marine life and bring attention to whaling practices. His dedication to ocean conservation has made him a globally respected advocate for the environment.
