초록 ▼

A method of printing is provided where printing is using a first printing unit having redundant nozzles. Then, the method may include stopping the printing with the first printing unit while continuing the printing with active nozzles of a second printing unit. The method may include inspecting the first printing unit and identifying faulty nozzles, then designating the faulty nozzles as inactive and designating inactive nozzles of the first printing unit as a new active nozzle. According to some embodiments the method may include moving the first printing unit to an inspection zone prior to inspecting while continuing the printing with active nozzles of a second printing unit and moving the first printing unit back to the printing zone after inspection and continuing the printing with the first printing unit.

1. A system for producing printed electronics by depositing conductive ink, the system comprising: a housing configured to house at least one movable print unit and a motor configured to move the at least one movable print unit, wherein the at least one movable print unit includes a plurality of nozzles configured to deposit patterns of electrically conductive material on an object;a conveyor configured to move the object relative to the housing;a memory for storing a print file containing specifications of a printed electronics pattern; anda controller configured to selectively move the conveyor in a manner enabling the electronics pattern to be printed on the object, wherein the controller is configured to cause printing of multilayered conductive lines forming a conductive path on the object in a single pass,wherein the housing is further configured to house a plurality of movable print units, and each of the movable print units being independently movable relative to the other movable print units during printing and including one or more fixed print heads, and wherein positions of the plurality of movable print units are determined by an optimization calculation; andwherein the optimization calculation takes into account: specific image data; andnozzle status data, wherein nozzle status data includes nozzle jet direction. 2. The system of claim 1, wherein the conveyor includes a platform defining a width of a print area. 3. The system of claim 1, wherein the housing is located in a fixed position facing the conveyor. 4. The system of claim 1, wherein the housing is configured to move the at least one movable print unit relative to the conveyor. 5. The system of claim 1 further includes a visual image detector, the visual image detector being configured to acquire images of droplets of the conductive material deposited from the plurality of nozzles indicating conditions of the plurality of nozzles. 6. The system of claim 1, wherein the housing is further configured to house a plurality of movable print units configured to move along a plurality of printing axes, and wherein at least two of the print axes overlap. 7. The system of claim 1, wherein the controller is further configured to: designate a first subset of nozzles as active nozzles and a second subset of nozzles as inactive nozzles;move the conveyor to locate the object underneath the first subset of nozzles; andinstruct the first subset of nozzles to print the electronics pattern on the object. 8. The system of claim 1, wherein the at least one movable print unit includes multiple movable print units and the controller is further configured to use data regarding relative strengths of the plurality of nozzles to determine a homogenized print head arrangement for the multiple movable print units. 9. The system of claim 1, wherein the at least one movable print unit includes multiple movable print units and the controller is further configured to select a first subset of print heads for depositing material on a substrate, while a second different subset of print heads is undergoing a maintenance procedure in a position outside of a print area. 10. The system of claim 1, wherein each line is printed using a repeating pattern of output. 11. The system of claim 1, wherein the optimization calculation comprises: determining a homogenized print head arrangement for the plurality of moveable print units. 12. The system of claim 1, wherein the positions of the plurality of movable print units are capable of being dynamically changed during printing by the controller.
