In doing so, this technique--which used to be measured by millimeters per second--can now cover five meters in one second. For the race car pictured above, that means rapidly laying down 100 layers of hardened resin each consisting of 200 single lines each in just four minutes. The race car itself is just 285 micrometers long and has to be imaged with a scanning electron microscope. But because the technique is now so fast, researchers now say this super-high-resolution fabrication technology can be applied to larger objects as well.
