Micro 3-D Printer Makes Dust Mite Size Spacehip |
 As
with most things, once a physical entity or concept has been produced
there is always the 'need' to build one on the macro scale and on the
micro scale. Here we have a 150-mm-long spaceship that was built by
German's Nanoscribe
GmbH using a 3-D laser photolithography printer. A scanning electron
micrograph was needed to capture a picture of the model due to its smallness.
It took about 50 seconds to create the model out of a photosensitive
powder (a video captures the process). Of course the purpose of the
exercise is not to be able to create spaceships the size of a dust mite,
but to demonstrate the capability using an object that the public will
be familiar with and impressed by. A micro-size 3-D model of a fountain
pen just wouldn't cut it.
