3-D printed prosthetics help kid athletes compete

Children who use prothetics can quickly outgrow the expensive devices, but 3-D printing could make them cheaper and more efficient, Autodesk scientist Andreas Bastian told CNBC on Friday.

"There hasn't been an economical way of making prosthetics as they outgrow them at roughly the same rate they outgrow a pair of shoes. So if your shoes are costing thousands of dollars, it just doesn't make sense to keep buying them," Bastian said on "Squawk Box."

On the show, Autodesk technology futurist Jordan Brandt pointed out another benefit to 3-D printing.

"If you look at 3-D printing at large, what you're able to do right now is quickly iterate and customize things," he said.

This technology could also be translated into sports, added Eric Marcal, a kayaker born without his left hand.

"[With this], I can pull back much easier than I would've been able to," Marcal told CNBC.
