Abstract
In a laser-assisted deposition system, a uniform layer of material is coated onto a donor substrate at a coating system, and portions of the material are jetted from the donor substrate to a receiving substrate at a printing unit, leaving residual portions of the material on the donor substrate. In order to not waste the residual portions of the material, the donor substrate with the residual portions of the material is returned to the coating system where the residual portions of the material are aggregated into a blob and subsequently recoated onto the donor substrate. The blob may be formed by translating the residual portions of the material towards an interface formed by two coating rollers, a squeegee and the donor substrate, or a film and the donor substrate.
