Researchers have discovered that coral skeletons, which are complex and resistant to damage, are valuable for various applications in various sectors. They studied how these animals use calcium carbonate to biofabricate entire underwater cities and compared their 3D-printed recreations to those made by 3D printers. The study suggests that while we have not yet replicated the toughness of coral skeletons in our own hands, 3D printing and other methods could offer sustainable solutions for the future. The research also suggests that replicating corals' mineral and organic properties into materials that are equal and superior to those of synthetics. However, this approach involves creating a living system in which microbes and cells can grow and heal themselves using live organisms. The researchers believe this could yield significant yield in future fabric-like materials.
