You’ll have heard of 3D printing. Now there’s nano 3D printing, which uses a laser to print things as small as 100 nanometres – about 1000 times thinner than a human hair. It is far more revolution than evolution.

It is simple enough to print something big. Nano printing allows you to make a big object by printing lots of tiny objects and joining them together. This allows you to imbue that big object with special powers. A 3D printed bone scaffold (left), and a bone scaffold being colonised by cells (right, cells in green). The scaffold is about the width of a human hair.Credit:Nanoscribe The technology was pioneered by the Karlsruhe Institute of Technology’s Professor Martin Wegener, who […]
