ABSTRACT:
A microfluidic printing apparatus includes at least one ink reservoir; a moveable plate having a plurality of delivery chambers in an array each for forming an ink pixel, and a plurality of microchannels connecting the reservoir to a delivery chamber; and a plurality of microfluidic pumps each being associated with a single microchannel for supplying ink to particular delivery chambers. The moveable plate moves between different positions for permitting the delivery chambers for sequentially delivering ink from an associated microchannel into its associated delivery chamber to control the amount of ink delivered to each delivery chamber; and a computer for controlling the microfluidic pumps and the movement of the moveable shutter plate for causing the correct amount of ink to be conveyed into each delivery chamber.
