  • System and method for detecting and remediating split inkjets in an inkjet printer during printing operations
    Patent number: 11850861
    Abstract: A method analyzes image data of a test pattern printed on an image receiving member by a printer to identify split inkjets in the printheads of the printer. The test pattern is formed by operating each inkjet of a printhead to form a dash and the areas of the dashes are compared to an average dash area to identify split inkjets. Firing signal parameters for the split inkjets are adjusted and subsequent firing signals are generated using the adjusted parameters. Image data of the pixels formed by the split inkjets are analyzed after the split inkjets have been operated using the adjusted firing signal parameters. If the pixel size for a split inkjets indicates that the split inkjet has been remediated, then the firing signal parameters are returned to their nominal values.

  • Sewing method and apparatus to increase 3D object strength
    Patent number: 11840784
    Abstract: An addition to additive manufacturing sews a number of printed substrate sheets together using industrial sewing machine technology. Portions of the final 3D object that will be solid are sewn together into bundles of the object with a needle protruding through the top of the bundle via a sewing machine with a looping mechanism connecting the thread loops under each bundle of printed substrate sheet layers. This will result in many well connected stack bundles that are then stacked in alignment to form the final stack. During heat and compression, the stitch thread may bunch together and become entangled with the cooled plastic of the final solid 3D object. Removal of the excess substrate may proceed as usual, since the sewing is applied only in the solid portions of the final object. The end result will be a part with much higher strength in the Z axis.
