High speed fabrication of race car

In the video, a race car with dimensions of 330x130x100µm3 is fabricated. The structure consists of 100 layers, each made of an average of 200 polymer lines. It is finished in 4 minutes and resembles the CAD file at a precision of ±1µm.

A racing car in the photo above has a length of 100 microns. It was established in Vienna University with a special 3D-printer from the resin, which polymerizes under the action of laser radiation. Microsculpture is made up of 100 consecutively deposited layers, and the whole process only took about four minutes.
