Saving coral reefs by 3D printing more?

Can we save the coral reefs by 3D printing more? Not reefs themselves, of course: those are built by living creatures, the coral ... but by 3D printing the substrate that corals can attach to and kickstarting the process of reef construction. In this TechFirst, we chat with marine biologist Astrid Kramer and 3D printing expert Nadia Fani about their crowdfunding startup, Coastruction. Scientists say we've lost half the world's coral reefs, and that puts a quarter of the world's fish at risk. Astrid and Nadia are trying to help reverse that, with the help of 3D printing and local groups all over the planet. Their proposed 3D printer uses sand and other local materials, and can adapt the size and shape of the substrate to local needs as determined by depth, tide, waves, shoreline, and more.
