Abstract: An additive manufacturing process comprising adding a support to an object model to create a modified object model f an object with a support to be built. The support extends from an object end coupled to the object to a distal end to be engaged with a carrier to support the object. A build model is created by arranging the modified object model within a virtual build volume with the distal end of the support at a defined location within the virtual build volume. Instructions are then provided to build a build cake corresponding to the build model, the build cake comprising the object with support and non-solidified build material.

Abstract: In one embodiment, a roll spindle comprises two roll supports and a differential.

Abstract: A method in a printer comprising a first printhead to dispense a first printing fluid and a second printhead to dispense a second printing fluid, the first and second printheads being arranged on a common scan axis that is substantially perpendicular to a media advance direction. The method comprises controlling movement of the first and second printheads relative to a media being printed, between a first index position and a second index position, the second index position being downstream of the first index position, and wherein the movement occurs during a time period between a forward scan and a reverse scan of the first and second printheads across a media being printed.

Abstract: In some examples, a first heating stage heats a print medium to a first temperature in a printing region when printing latex ink on the print medium, and a curing heating stage heats, in a curing zone, the print medium to a curing temperature greater than the first temperature to cure the latex ink on the print medium. A cooling stage located between the first and curing heating stages cools the print medium by directing a first part of airflow from the cooling stage to a printing zone, the cooling performed after the print medium has been heated by the first heating stage and prior to heating of the print medium by the curing heating stage. A second part of the airflow is directed from the cooling stage to the curing zone.

Abstract: Methods for curing ink printed on a print medium are disclosed. The methods comprise heating air to a temperature suitable for curing the ink, and blowing the air through a plurality of holes onto the print medium.

Abstract: In one embodiment, a roll spindle comprises two roll supports and a differential.

Abstract: Systems and methods for printing are described. One example is a tension module for a printer including a throughput roller including a length to diameter ratio of at least 10:1 and a material on the surface thereof having a friction coefficient value less than 1. In addition, the module includes a plurality of pinch rollers arranged parallel to the throughput roller and, the pinch rollers supporting the throughput roller and providing a pressure on a print medium when passed along the throughput roller. Further, the module includes a motor to rotate the throughput roller. Still further, the module includes a tension lever including a plurality of stops, each of the stops being associated with one of a plurality of tension settings. Manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the pinch rollers on the print medium.

Abstract: In one example, a platen for supporting a print substrate includes multiple support surfaces that together define the full extent of a substrate support area of the platen. Each support surface is oriented parallel to other support surfaces along a line that is oblique to a direction the print substrate is to pass over the support surfaces when the platen is in use in a printer or other liquid dispenser.

Abstract: A controller controls a first heating stage to heat a printing medium to a first temperature in a printing region when printing latex ink on the printing medium, and controls a second heating stage to heat the printing medium to a second temperature greater than the first temperature in a curing region to cure the latex ink on the medium. The controller controls a cooling stage located between the first and second heating stages to cool the printing medium after the printing medium has been heated by the first heating stage and prior to heating of the printing medium by the second heating stage.

Abstract: In one example, a printhead assembly for dispensing liquid on to a substrate includes a first printhead to dispense a first liquid and a second printhead to dispense a second liquid different from the first liquid. The position of the first printhead is not adjustable along a line of substrate advance and the position of the second printhead is adjustable along the line of substrate advance.

Abstract: A printing device and method for printing a latex ink on a printing medium is disclosed. The printing device comprises a heating stage for heating the medium at least during printing the latex ink on said medium, a further heating stage for curing the latex ink on the medium and a controller arrangement for individually controlling the heating stage and the further heating stage, whereby the controller arrangement is arranged to reduce the heat output of the heating stage during a non-printing mode of the printing device and to reduce the heat output of the further heating stage during a non-curing mode of the printing device.

Abstract: Systems and methods for wide format ink printing are described. In one embodiment, a tension module for wide format inkjet printers is described which includes a throughput roller comprising a material having a length to diameter ratio of at least 10:1 and a friction coefficient value less than 1.
