Abstract: A printer for digital printing in which conductive ink is deposited in metered amounts on a substrate. The printer includes a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. A computer controls movement of the wire by controlling the rotation of the wheel. As the motor rotates the wheel, conductive ink contained within the paint reservoir coats the wire and is drawn by the wire in front of an air stream, which pulls the conductive ink from the wire and carries it toward the substrate. The digital printing of conductive ink can be used to form conductive patterns, such as circuit elements, on the substrate.
