One of them, calcium carbonate (CaCO 3), is standardly used as filler for the processing of polymeric materials. Much effort was dedicated to improving the properties and processing of such printed filaments, and various types of inorganic and organic additives have been found to play a beneficial role. The most common type of 3D printing uses the fused filament fabrication (FFF) method, in which materials based on thermoplastics or elastomers are processed into filaments.

Nowadays, additive manufacturing-also called 3D printing-represents a well-established technology in the field of the processing of various types of materials manufacturing products used in many industrial sectors.

Direct printing is slower and lower resolution, but it allows for individual customization and the creation of larger structures. Creating a mold means the structure can be easily and quickly reproduced, but the curing process limits the size of the mold. The two approaches offer complementary advantages.

In the second method, the support structure is printed directly using the CCP ink. The final structure is produced by filling the mold with CCP ink. In the first method, the model is printed, and the print is then used to cast a silicon mold. It also incorporates two different printing methods, both of which start with a scanned model of a coral skeleton. Unlike existing approaches, which rely on passive colonization of the printed support structure, 3D CoraPrint involves attaching coral microfragments to the printed skeleton to start the colonization process. Tests in aquariums have shown that CCP is nontoxic, though the researchers are planning longer-term tests. The team developed and tested a new approach called 3D CoraPrint, which uses an ecofriendly and sustainable calcium carbonate photo-initiated (CCP) ink that they also developed. However, most efforts have used synthetic materials, though work is being done to use hybrid materials. Researchers have tested several approaches to print coral support structures. In essence, the idea is to provide the corals with a head start so the reef can recover faster. “ Coral microfragments grow more quickly on our printed or molded calcium carbonate surfaces that we create for them to grow on because they don’t need to build a limestone structure underneath,” says Hamed Albalawi, one of the lead authors of the study. Here is the thing, the resulting restoration is slow because corals deposit their carbonate skeleton at a rate of just millimeters per year.Ĭharlotte Hauser and her team are exploring the use of 3D printing to speed up the process. Usually, to restore reefs, experts use concrete blocks or metal frames as substrates for coral growth. Coral reefs around the world are suffering from warming oceans and increasing pollution. For those who do not know, coral reefs are made up of rigid porous “skeletons” inhabited by the tiny coral polyps that built them.
