Micromechanical gears. Coloured scanning electron micrograph (SEM) of planetary gear components from a miniature electrical motor. The parts were made from a reservoir of an acrylic liquid, which was polymerized in the areas where computer-guided lasers were aimed at it. Planetary gears comprise a series of gears around a central (sun) gear, allowing all the gears to share an axis. Magnification: x12 when printed 10 centimetres wide.
