3D printing enables the smallest complex micro-objectives
3D printing revolutionized the manufacturing of complex shapes in the last few years. Using additive depositing of materials, where individual dots or lines are written sequentially, even the most complex devices could be realized fast and easy. This method is now also available for optical elements. Researchers at University of Stuttgart in Germany have used an ultrashort laser pulses in combination with optical photoresist to create optical lenses which are hardly larger than a human hair.
