1. A method for printing a plurality of discrete film segments of substantially uniform thickness over a target print area, comprising:

  • providing an array of multipore nozzles, wherein each multipore nozzle is fabricated to have a plurality of micropores arranged in a pattern and further wherein each multipore nozzle is configured to deposit a discrete film segment over the target print area;

    directing a gas stream comprising a carrier gas carrying a vaporized material through the array of multipore nozzles, wherein the gas stream is divided into a plurality of micron-scale gas sub-streams by the plurality of micropores in the multipore nozzles, each gas sub-stream comprising the carrier gas carrying the vaporized material;

    directing the gas sub-streams comprising the carrier gas carrying the vaporized material onto a substrate; and

    condensing the vaporized material on the substrate to form a plurality of substantially solid discrete film segments;

    wherein the plurality of micron-scale gas sub-streams from each multipore nozzle are positioned relative to each other to deposit a discrete film segment having a substantially uniform film thickness profile over the target print area.
