3D Printed Coral Will Save our Marine Life

The endangerment of coral reefs and the effects it is having on our marine life is alarming. Researches have been searching for a way to help this situation. One idea is to replace those damaged reefs with 3D printed supplement models.

“New research by the University of Delaware’s Danielle Dixson and UD alumnus Emily Ruhl has shown that 3D-printed objects do not impact the behavior of coral-associated damselfish, or the survival of a settling stony coral. Further, the study demonstrated that fish showed no preference between materials used to 3D-print artificial corals. This opens the door to using environmentally friendly materials, such as biodegradable cornstarch instead of plastic. With mounting concerns about plastic pollution in the marine environment, it is timely evidence that can support environmentally conscious decisions about what is put in the ocean.

In laboratory experiments, the researchers studied the behavior of damselfish and mustard hill coral larvae in the presence of a coral skeleton and four 3D-printed coral models made from different filaments. Blue-green damselfish (Chromis viridis) are a common coral-associated fish found in the Indian and Pacific Oceans, while mustard hill corals (Porites astreoides) are a stony coral found in the Caribbean Sea.”
