This is a concept test of a mechanical prosthetic finger. The e-NABLE community of volunteers http://enablingthefuture.org/ makes 3D-Printed prosthetic hands available free to children. A new material, Taulman Bridge Nylon filament looks promising for creating 1-piece models with living hinges using FDM printing. This experimental finger will hopefully fit in the forefinger slot of the Flexy-Hand 2 by Gyrobot. The goal is to design a hand with fingers that can be printed in one piece so that the assembly will be reduced to stringing up the tendons.
The model was tested in our early days of printing nylon, and the testing suggests that living hinges on nylon fingers could be successfully developed. More testing is needed.
