CBS Evening News reports that instead of paying tens of thousands of dollars for a factory-made prosthetic hand, the 12-year-old's father, Paul McCarthy, printed one.
The Massachusetts dad had spent two years searching for affordable ways to give his son a prosthetic. Finally, he found inspiration on the Internet. He told Fox that he found a YouTube video detailing the work of Ivan Owen, who used a 3D printer to create a prosthetic hand for a 5-year-old in 2011. Following in Owen's footsteps, McCarthy used a 3D printer purchased for his son's school and began working on the hand with his son.
