3D printing could be the key to saving coral reefs

The death of coral reefs is one of the many consequences of human impact on the Earth. This, of course, is dangerous not only for marine life itself, but also for the survival of the growing human population on the planet. We received an encouraging report today and it is that scientists can use 3D printing to restore the world’s reefs.

Known as 3D Innoreef, this proposal aims to restore coral reefs around the world. According to data obtained by Chulalongkorn University in Thailand, the design of this technology, together with its composition, could help restore the existence of royal corals from 3D printed copies.

Work, They are based on a connection system similar to that used in LEGO pieces.. In this way, 3D models of corals are printed, which are subsequently attached to the ocean floor. The result is impressive and demonstrates nature’s inherent power of survival.

3D printing becomes an ally

Placed in groups of three, Innoref’s 3D elements are attached to the ocean floor. This creates a sort of refuge for coral larvae, known as planulas, which can begin to swim freely. Subsequently, these plans they will settle in the recesses of the 3D printed copies, where they will generate elements such as calcium carbonate.creating a real reef from synthetic.

What material are these 3D Innoref 3D printers made from? As they comment made of concrete. After printing, the concrete is coated with calcium phosphate, an essential element for the growth of natural corals.

For now, the technique being studied by developers at Chulalongkorn University seems to be bearing fruit. By installing several Innorefs groups on the coast of Chonburi Province in Thailand in 2020, much faster growth of coral reefs was found in the area. In fact, they grew faster than their natural counterparts, about 3-4 centimeters per year.

The benefits of 3D Innoref are not limited to coral growth.
