Inexpensive home-brewed prostheses created using 3D printers


Two low-cost, printable prostheses highlight the potential impact 3D printing could have on the quality of life for millions as the technology becomes more accessible around the world. Gizmag reports.

-- A complete set of mechanical prosthetic fingers - The design is free on Thingiverse with a public-domain license:

The fingers are controlled via cables and return bungees, which, while relatively low-tech, provide a functional and comfortable to wear prosthesis. The design can also be scaled for other individuals using Makerware software.quotesmarksleft.jpg

-- A prosthetic hand that could be cheaply created on a 3-D printer for amputees in developing countries:

The hand is purely mechanical and has no electronic parts. Inventor Eric Ronning, a mechanical engineering sophomore, could make the hand's design available on open-source 3-D printing sites such as Thingiverse, where it could be easily replicated for about $20.quotesmarksleft.jpg
