Systems and methods for residual material collection in laser-assisted deposition

A printing system, comprising a coating system configured to create a uniform layer of a material on a donor substrate, and a printing unit configured to transfer the material in portions from the donor substrate onto a receiving substrate such that residual portions of the material remain on the donor substrate, wherein the printing system is configured to return the donor substrate having the residual portions of the material remaining thereon to the coating system for reclamation of the residual portions of the material on the donor substrate,

• wherein the coating system includes a dispenser of the material to deposit the material onto the donor substrate, and the coating system is further configured to transport the donor substrate with the material thereon towards and through a gap with a first gap width defined by a first coating roller and a second coating roller to create the uniform layer of the material on the donor substrate, the uniform layer of the material having a thickness that is defined by the first gap width, and
• wherein the reclamation of the residual portions of the material on the donor substrate is effected (i) by modifying the gap to have a second gap width that is narrower than the first gap width, and (ii) using a film at least partially disposed within the gap to aggregate the residual portions of the material on the donor substrate while the residual portions of the material are translated towards an interface between the film and the donor substrate, the interface disposed within the gap.
