Advanced prosthetic arms and legs can make life easier for a lot of people. They are not always affordable though. Open Bionics is working on bionic hands with 3D printed components to bring down costs. These prosthetic arms are not only good looking but can be controlled through sensors placed on your muscles. You can flex your muscles to move the hand. The fingers can be moved independently and allow for different gripping modes.

As more mechanical components of the hand can be printed, the total cost drops dramatically. These prosthetic hands are made using flexible TPU and rigid PLA materials. They cost $1200, which is only a fraction of what premium robotic hands cost.
