Abstract: Systems and methods for coating of a thin film with a viscous material, such as a liquid, a paste, or an adhesive, at a desired thickness. In such a system, two films move adjacent to one another, optionally in opposite directions, atop two rollers separated by a known gap that defines a coating thickness, with the material being transferred from one film to the other. The rollers may be maintained in their relative positions by springs and/or linear actuators and positioned using linear encoders. In alternate arrangements, the material to be coated could be low viscosity material such as a polymeric solution. Air knives may be provided near the gap to create an air flow that aids in preventing the free flow of low viscosity materials outside the bounds of the film during coating.

Abstract: Systems and methods in which dot-like portions of a material (e.g., a viscous material such as a solder paste) are printed or otherwise transferred onto an intermediate substrate at a first printing unit, the intermediate substrate having the dot-like portions of material printed thereon is transferred to a second printing unit, and the dot-like portions of material are transferred from the intermediate substrate to a final substrate at the second printing unit. Optionally, the first printing unit includes a coating system that creates a uniform layer of the material on a donor substrate, and the material is transferred in the individual dot-like portions from the donor substrate onto the intermediate substrate at the first printing unit. Each of the first and second printing units may employ a variety of printing or other transfer technologies. The system may also include material curing and imaging units to aid in the overall process.

Abstract: Systems and methods for dispensing liquid materials as may be used in applications for coating flexible films and the like. Such a film may be coated by dispensing a rheological material onto its surface while drawing the film through a gap between a pair of rollers. The gap defines the thickness of a layer of the material applied to the film and is maintained at a desired width by microwires positioned through the gap. Another film across the gap from that to which the rheological material is applied aids in the coating of the layer and a contact area of the second film may be adjusted relative to the gap, e.g., when changing materials or when the coating film becomes abraded or deformed.

Abstract: A system of solid free form fabrication (SFF) is disclosed. The system comprises: receiving SFF data collectively pertaining to a three-dimensional shape of the object and comprising a plurality of slice data each defining a layer of the object. The system also comprises, for each of at least a few of the layers, dispensing a building material on a receiving medium, straightening the building material, and selectively ablating the building material according to respective slice data.
