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.
An inside look at the LEGO Group's prototyping lab where they turn 3D CAD designs of their products into functional 3D prototypes using an Objet 3D printer. As seen on the Objet blog: http://blog.objet.com/
