The underwater coral reefs of the world are some of our Earth’s most diverse and fascinating, living, breathing ecosystems. Unfortunately due to pollution, climate change and other negative factors, coral reefs are in extreme danger of extinction, with 90% of Earth’s coral projected to die out by 2050.

However, efforts have been underway around the world to provide the world’s oceans with 3D printed coral reefs which may be able to keep the reef biodiversity safe and intact. Over the past several years, many fascinating technologies have emerged from growing natural coral from 3D printed structures to fish preservation, with a variety of materials and 3D printing technologies.
