3D-printed coral reefs

rrreefs is adopting an innovative approach to counteract the global extinction of coral: the interdisciplinary team uses self-developed, modular clay structures from 3D printers to build artificial reefs that provide young corals with optimal conditions for growth. Within a few years, these structures develop into resilient and self-sustaining coral reefs.

Coral reefs are among the most valuable and, at the same time, most endangered ecosystems on our planet. Although they cover less than 1 per cent of the oceans, they are home to around 25 per cent of all marine species, making them one of the most species-rich habitats on Earth. However, due to climate change and the associated rise in sea temperatures, polluted oceans, and heavy use of coastal waters, they are dying off at an alarming rate. This results in the loss of irreplaceable biodiversity and habitats, as well as essential protection for coastal regions. Corals not only prevent erosion but also act as breakwaters, serving as a natural barrier against storm waves and tsunamis. They also secure the livelihoods of millions of people worldwide and function as natural CO₂ reservoirs.

rrreefs accompanies every restored reef with scientific studies and close monitoring. The team uses the results to continuously improve the reef structures. The holistic approach in the fight against coral extinction also includes art and educational projects. rrreefs considers art as a catalyst for individual action and social change: the reef structures become art objects in exhibitions that stimulate dialogue and raise awareness of the importance of coral reefs. The educational programmes and workshops with local partners, through which the association ensures the necessary transfer of knowledge, are also aimed at achieving this.

With our support, rrreefs is revitalising a destroyed reef in Pujada Bay, Philippines. Around 250 square metres of reef habitat will be created there, and the reef’s regeneration and the development of biodiversity will be scientifically monitored for three years.
