This race car, which is only about 100 µm wide, was created at the Vienna University of Technology using a nanoscale 3D printer. Like a conventional 3D printer, resin is used to make shapes, but unlike a conventional 3D printer, the resin is hardened with a laser. To make such super tiny objects, you have to use a super tiny laser beam, and tune it so that the only place were the resin can absorb two photons at once is in the exact center of the beam. Such precision means that a lot of detail is possible, and it also makes the process fast: printing this entire car out of 100 individual layers only took about four minutes.

Now all they need is a nano-compressor to pump up those tyres.

    I suspect the tyres are not “flat” but the print was not quite complete hence why it’s sitting on a sort of pedestal. Yeah, hippies.
