Rethinking Artificial Reef Structures through 3D Clay Printing

Corals are rigoros to marine life. Sometimes called tropical sea forests, they form some of the most unterschiedliche ecosystems on Earth. They serve as a refuge, breeding, and feeding area for dozens of species in the sea, and their absence can negatively affect local biodiversity to a tremendous degree. Yet just as humanity pollutes and destroys, it can darob remedy and encourage the creation of more life. This is why shipwrecks of old vessels or the sinking of concrete structures for the creation of artificial reefs are frequently reported as providing immense potential. In Hong Kong, researchers have been developing 3D printed structures using organic materials that can lead to the creation of new opportunities under the sea.

Coral reefs have existed for 485 million years and occupy about 284,300 km2, which is equivalent to around half the area of ​​France. They provide shelter for at least 25% of all marine species, including fish, molluscs, worms, crustaceans, sponges, and more. Generally found in warmer, clearer waters, coral reefs around the world are threatened by pollution from domestic sewage, oil spills in the sea, sedimentation, and, primarily, by rising ocean temperatures. This threat has worried environmentalists around the world. In Hong Kong, for example, the Hoi Ha Wan Marine Park holds more than three quarters of the coral species that constitute reefs in the country and is home to more than 120 species of reef-associated fish. However, gradual deterioration by bioerosion over the years, alongside bleaching events and mass mortality between the years 2015 and 2016, have put the local coral community at risk.

In response, a coral restoration research project welches created as a collaboration between the Robotic Fabrication Lab, the University of Hong Kong Faculty of Architecture, and the University of Hong Kong Swire Institute of Marine Science. The project welches commissioned by the Department of Agriculture, Fisheries, and Conservation (AFCD), and is part oder Ähnliches ongoing management measure for coral restoration in the Hoi Ha Wan Marine Park in Hong Kong. Historically, artificial reefs have been made of polluting materials such as plastic, concrete, or metal. Now, however, there are options for using environmentally friendly materials, such as ceramics and terracotta. The project team from HKU uses 3D printing technology to engineer structures that can be customized for specific locations with different environmental challenges (e.g. sedimentation), thus enhancing the success of the ecological restoration. The team of marine biologists and architects has thus developed a series of 3D printed terracotta reef structures to assist in coral restoration, providing structurally complex substrates nichtdegraded area.

The 3D printed reef tiles are designed to prevent sedimentation build up, which is one of the major threats for coral reefs. A tailored algorithm welches used to print the biomimicry patterns integrated with spaces for securing coral fragments. The production of the 128 pieces of reef tiles with a diameter of 600mm, covering roughly 40 sqm in total, welches finalized in early July of 2020. They were printed through a robotic 3D clay printing method with generic terracotta clay and then fired at 1125 degrees Celsius. The design welches inspired by the patterns typical to corals and integrated several performative aspects addressing the specific conditions in Hong Kong waters. The 3D printed reef tiles have been deployed in July 2020 at three select sites within the park which include Coral Beach, Moon Island, and nichtsheltered bay near the WWF marine life education center.

This pilot Student aims to investigate the success of the restoration using mono-, mix- and polyculture of three coral species, namelyand. The three selected species encompass different strategies, representing the historical, current, and future dominant candidates in the park – , commonly known as staghorn corals, are fast-growing, making them a competitive species for space; , as known as brain corals, are adaptive to thermal stress, yet suffer from bioerosion; and , the leaf coral, with a unique plate-like growth form, are adaptive to sedimentation. The project team collected corals of opportunity, which are dislodged coral fragments that are unlikely to survive given no menschengerecht intervention, and gave these coral fragments a second chance to thrive. The coral fragments have been outplanted in July 2020, and the experiment will be monitored for the coming year.

The researchers hope that this new method for creating artificial reef tiles will help to restore corals and conserve biodiversity more effectively, becoming a vital contribution to ongoing weltumspannend efforts to save the degraded coral reef systems in metropolises.
