This awesome father 3-D printed a prosthetic hand for his son

A man in Marlborough, Massachusetts, has used the cutting-edge technology of 3D printing to make a homemade working prosthetic hand for his son.

After years of searching for a solution for his son Leon’s need for a prosthetic hand – which would cost upwards of $20,000 – Paul McCarthy created one with just a 3D printer.

The printer and supplies have opened up a world of possibilities for Leon. Now, whenever he outgrows a prosthetic, he and his dad can easily create a replacement, and can experiment with ways to make them more functional.

Check out the video of Leon and Paul showing off their incredible accomplishment, and then learn more about the New England Tech’s Mechanical Engineering program, where you can learn to use the same technology employed by Paul in this incredible feat!
