Watch A Spaceship The Width Of A Hair Get 3-D Printed In Real Time | Popular Science


Some of the tiniest (although technically not truly nanoscale?) and speedy 3D printing. The process, called two-photon polymerization, focuses an infrared laser (essentially using a microscope in reverse) into a photosensitive resin. Where the spot where the laser is most intense polymerizes and hardens. Once the rest if the resin has been washed away you are left with the printed object.

This video shows a Hellcat spaceship from Wing Commander Saga, the length of which is about the width of a human hair – 125µm x 81µm x 26.8µm (l x w x h), being printed in less then 50 seconds by one of nanoscribe‘s 3D printers.
