3D Printed Clay and Oyster Shell Coral Reef to Enhance Marine Biodiversity

Using advanced manufacturing technology and digital fabrication techniques to design a modular structure which aims to promote coral growth and marine biodiversity.

For more information on my initial project proposal and to see how my idea has developed please check out my Implications and Applications Week.

I have decided to adapt my proposal to be more focused on the design elements of my module as I realised trying to achieve microbial induced precipitation (MICP) would not have been feasible in the time frame, it was also proving a challenge purchasing the required bacteria. I will now be looking at how I can use modelling software such as Rhino 3D, Grasshopper and Houdini to generate a module which promotes marine biodiversity and optimum larvae attachment. The material aspect will be focused on clay and/or calcium carbonate powder sourced from waste oyster shells.

I have partnered with a great 3D printing coral reef restoration organisation, RRReefs who have offered to take my module out to their site in the Philippines for further testing against their existing artificial reefs.

Below is my conceptual design poster.

Location¶

Pujada Bay, Philippines

In February 2024, RRReefs implemented their biggest reef project yet which spans over 100m² with 820 3D-printed modules made from terracotta clay. This project has provided a foundation for the marine ecosystem to thrive without further maintenance.

Having been declared a marine protected area in 1994, Pujada Bay, with its sheltered waters provides a suitable environment for coral growth and is a biodiversity hotspot of diverse ecosystems.

The Philippines contain almost 10% of the world’s coral reefs with exceptional biodiversity, but to date, 98% of the country‘s reefs are classified as threatened, with 70% at high or very high risk. It is estimated that less than 2% are still in excellent health status.

Call to Action¶

I have created a resources page for climate action - providing information on useful websites, powerful activists and insightful documentaries/podcasts to engage with.
