Barber said his team is now looking to commercialize the discovery and even thinking it could be produced using 3D printing. The research also discovered that limpet teeth are the same strength no matter what their size, which overcomes a problem with many scaled up materials - they have "lots of flaws and can break more easily than a smaller structure, which has fewer flaws and is stronger.". Many products featured on this site were editorially chosen.
I thought, wow, this was interesting. “Engineers are always interested in making these structures stronger to improve their performance or lighter so they use less material.”. "It's going to be in transport structure because you save energy if you make a car half as light, reduce the weight by 50 percent," he said. Most limpets are less than 3in (8cm) long, but a West Mexican Limpet grows to be 8in (20 cm). What you believe about how life began really does matter.
