This 3D printed bionic arm is also a smart one, so it connects to the wearer's smartphone. Developed by Japanese company Exiii, Handiii enables users to control the myoelectric hand with their nerves and muscles.

Handiii acts as a more affordable alternative to the expensive and homogeneous prosthetics at $300 USD. A regular prosthetic hand is hard to customize, let alone repair. The Handiii, however, uses an EMG sensor to read electric signals from the wearer's movements. Smartphones can then translate muscle signals into arm motions, allowing the user to control the device more naturally and instinctively.

The 3D printed bionic arm is able to be printed in a wide range of colors and is easily produced and replaced if necessary.
