Su secreto es una tinta especial compuesta de nanopart\u00edculas de plata. Un l\u00e1ser en el cabezal de impresi\u00f3n hace que el compuesto fluido se solidifique nada m\u00e1s salir de su punta. Finalmente, un sistema de tres ejes capaz tambi\u00e9n de girar libremente permite dibujar estos alambres en cualquier forma imaginable.
