After South African carpenter Richard Van As lost his fingers in an accident he decided to create a low-cost prosthetic hand for people without fingers.
Dubbed Robohand, the hand was designed by Richard working with a designer based on the other side of the world in Seattle.
The hand is printed out of PLA plastic resin using a MakerBot machine and combined with cables and screws to make the finished prosthesis. It is designed to be worn on the hand and to grasp its fingers the user folds their wrist. The design for the hand is freely available online, allowing anyone with a 3D printer and a few additional parts to build their own version.
This 3D printed titanium lattice has been designed to protect probes in future missions to Mars.
The protection is designed for probes that are intended to collect samples from the Martian surface and then return to Earth. The lattice crush zones are designed to absorb the impact of the probe upon crash landing on the Earth's surface.
The protective lattice has been designed by the UK-based Manufacturing Technology Council.
This is a mock design of a robotic arm that would relay a sense of touch and temperature to its owner.
The arm is the work of a team at the University of Nottingham in England, which is investigating how it could use 3D printers to build electrical, optical and even biological functions into the arm.
