This 3D-printed cast looks awesome

Have you ever worn a cast? I have not. But friends have told me they're uncomfortable. Hot and itchy. Plus, they tend to get kind of stinky. No more. With the advent of 3D printers, 3D-printed casts take care of the smell and itch issues, and now a man named Deniz Karasahin has designed the next step: a custom cast with an ultrasound device to speed up bone healing.

Karasahin's Osteoid is just a design concept right now. But it's based on sound science: low-intensity pulsed ultrasound (LIPUS) has been found to reduce bone healing time by nearly 40% with just one 20-minute treatment a day. The therapy has been tricky to administer, because it requires placing ultrasound leads on the skin directly over the bone injury. That's impossible with an old-school plaster cast, but not with a 3D-printed one.

Since this is a design concept, you probably won't find it in your emergency room anytime soon. But projects like this show the ingenious things that can develop when great ideas in science and design come together. Someday, people with broken arms will walk around looking like cyborgs.
