Low-cost 3D printed hand suits man for daily needs (w/ video)
(Phys.org)—Jose Delgado, Jr., a 53-year-old man born without most of his left hand, has given positive feedback about a $50 3D prosthetic hand. He talked about all it can help him do in a video that was presented by the person who helped make the hand. Delgado's account, praising the hand for enabling good day to day functionality, made the rounds of tech sites this week. The story drew interest not only because this is a 3D-printed prosthesis but also because he said that, in a number of ways, he liked it better than his $42K myoelectric prosthesis. (A myoelectric-controlled prosthesis is an artificial limb that you control with the electrical signals generated naturally by your own muscles.) Delgado's myoelectric hand tapped into muscle signals on his arm to trigger the closing or opening of the fingers.
