College students 3D print out medical prosthetic hands: cost as little as $15

Ryan Bouricius, a university physics student from Ithaca College, once again demonstrated how 3D printing technology can be used to create functional and very affordable prosthetic hands. By making innovative design, reference and improvement of other open source prosthetics, the student can develop the prosthesis to grasp, hold, and even write.

It is well known that one of the medical applications of 3D printing is the production of functional prosthetic hands. While 3D printed devices may not be as smooth or unobtrusive as professional designs, an affordable and customized solution has been proposed to help many people who cannot afford expensive prosthetic implant treatments. Especially for children, as children have been growing, fixed-length prostheses can't meet their needs, and there is an easy way to make custom-made prosthetic hands that will be particularly attractive.

Borricius is a teaching assistant at the Ithaca Academy's 3D printing lab. Inspired by many open source designs, he created his own 3D printed manual prosthesis, which he can print and assemble 3D printed hands in a single day. After successfully completing his first hand, he decided to make some adjustments and improvements to his design.

First, Bouricius changed the direction of the thumb of the 3D printed prosthesis so that it could grip the object more effectively. He also made some other adjustments to improve the grip of the 3D printer. Like many other 3D printed hands, Bouricius' prosthetic movement is controlled by the user's wrist movement. During the development process, he tried to use the prosthesis as much as possible, not only to see how it works, but to better understand how to live with the prosthesis.
