A new exhibition dedicated to innovations in 3D printing has opened at the Science Museum in London.
The exhibition, called 3D: printing the future, includes a printed scaffold for a bladder and a skull, plus a prosthetic arm which features structural and electronic components printed simultaneously.
We also hear from the BBC's Evan Davis and meet his mini 3D self.
