University students use 3D printer to make prosthetic arm for young violin player

It took a year to get it right, but now Isabella Nicola, a 10-year-old from Fairfax County, Virginia, can comfortably play the violin, using her new pink prosthetic arm.

When she was born, Nicola's left arm was only partially developed. A year ago, five George Mason University students started to design a prosthetic for her, and they have spent the last 12 months working together on the perfect fit; she provided feedback for the students, who then tweaked the prosthetic — made with a 3D printer — to make it more comfortable. "I am very grateful," she told NBC Washington. "Without these people, I don't think I'd be able to play the violin. I don't think I'd be able to play any instrument." Catherine Garcia
