A maker of 3D printers for electronics, Nano Dimension builds machines like the DragonFly that print working circuit boards and antennas using special silver and dielectric inks — a fast, in-house alternative to traditional PCB manufacturing for engineers and product designers. The company was founded in 2012 in Ness Ziona, Israel, by a team of 3D-printing, electronics, and nanotechnology experts who wanted to speed up the slow work of prototyping circuits. Its DragonFly printers run "lights-out," meaning they can keep printing electronic circuitry around the clock with so little human help that you can literally turn out the lights and leave for the day.
