I've been astonished by the problems 3D printing has been used to solve. For me the most amazing developments have been in medicine.
The 3D printed implants used to reshape Stephen Power's face, after he was seriously injured in a motorbike accident, are astounding. Models and guides that helped the surgeons were also 3D printed.
I'm really excited to see how 3D printing could make medicine more personalised in future.
These implants, along with other medical advances, are on display in 3D: printing the future, in the Antenna science news gallery.
