2. Helping adorable animals get back on their feet.
Buttercup the duck was born with a backward left foot. Thanks to a 3D-printed design by Mike Garey, Buttercup can now walk comfortably again. Read more here. (Warning it’s one of the cutest things you’ll ever see.)
5. Powering our smallest devices.
Leave it to Harvard. Researchers there have figured out how to 3D print lithium-ion batteries that are “the size of a grain of sand.” This means more energy for lots of devices, from the newest smartphone to the smallest hearing aid.
8. Printing vital organs.
Wait lists are notoriously long for organ transplants. Wouldn’t it be a lot easier if you could just print a new one? Surgeon Anthony Atala is working on a project with a 3D printer that “uses living cells to output a transplantable kidney.” Mind = blown. Kidney = saved.
13. Saving the environment.
Some of the printers are helping to save the day just by the nature of how they work. The Filabot for example, “grinds and melts old plastic items to make 3-D printing self-sufficient.” So, if you need more “ink” for your 3D printer, you can just look in your recycle bin.
