Researchers at Technion University, Ben Gurion des Negev University and Bar Ilan University have collaborated on a project to help rebuild coral reef systems around the world using a 3D print model to create artificial coral structures Universities published.

With the global coral reef system worsening, the technology now being applied on the Eilat coast will help restore the diversity of the underwater ecosystem by introducing these fabricated structures into systems that are unlikely to be can regenerate itself.

Coral reefs around the world disappear for a variety of reasons due to natural and man-made causes, mainly due to overheating of waters affected by climate change, dynamite fishing, sunscreen chemicals, and invasive fish such as the lionfish, a species of fish that inhabits the inhabitants hunted by coral reefs.

Over 30 percent of the Great Barrier Reef, the world's largest coral reef system in the coral sea off the Australian coast, was thrown into the ground by heat waves in 201

6 and 2017, raising water temperatures for these natural systems to an uninhabitable level – scientists have indicated that as Earth's average temperature rises by another four degrees Fahrenheit, almost all coral reef systems around the world will be lost, used as essential nurseries. For many fish species that feed more than a billion people each year.

The 3D-printed reefs can mimic natural forms that attract different species of fish for artificial use. It is well known that many factors influence the possible recruitment of reef organisms, and especially fish. An important factor is the structural complexity of a coral colony that provides protection for the fish living there. The complexity of the coral structure has been shown to correlate with the species diversity of the reef, "the researchers said.

The 3D printer uses polylactic acid, a biodegradable and bioactive bioplastic derived from corn, manioc or sugarcane, to create columnar structures which are then incorporated into the water and individually planted with cultured coral to mimic the complexity of the coral reef ecosystems.

These efforts will theoretically lead important species of fish to return to these areas an attempt to revert to the barren reefs to completely reconstruct along the Eilat coast.

Scientists have used many different shapes, colors and materials to develop the final design product off the coast of Israel – leading indicators suggest The preferences of many of these species differ in contrasting combinations from Material and color while rejecting other combinations.

We are occupied by marine biologists and designers and are looking for new methods and tools to study the ecological functionality of coral morphology, "the researchers said." We believe that coral reef rehabilitation and management and the construction of artificial reefs are a better one Understanding the interactions of individual coral colonies with their inhabitants will require. "

In this particular study, scientists use 3D manipulation and printing to understand whether man-made structures can promote a natural ecosystem, the species of fish that are responsible for that The success of these ecosystems and the benefits of using advanced design tools such as 3D scanning and manipulation to create artificial corals are essential.

"A successful implementation of this study may improve our understanding of coral interactions with their environment Providing instruments for public exhibits such as large aquariums, thereby reducing the dependency on living corals, as well as valuable design guidelines and tools for the approach to matter, provide active re-establishment of coral reefs, "the researchers said.

"The biological results of the research need to be further processed and analyzed before they can be published, but the design part of the process ended with the second phase, in which 20 objects were installed for observation in the Red Sea and Invertebrates use the 3D printed corals and provide them with a good home to trust [in].
