Earth Agenda Foundation together with Chulalongkorn University’s Faculty of Veterinary Science, the Department of Marine and Costal Resources and SCG use 3D printing to create an artificial coral reef structure. Following its placement on the sea floor of the Gulf of Thailand in 2020, a variety of marine species have been seen on this complex, stable and durable underwater house. A broken piece of coral can grow on the 3D printed artificial coral reef over a period of time. (Photo courtesy of Earth Agenda Foundation)
