Abstract: An apparatus for printing an image onto a curved surface of a three dimensional article. The apparatus principally includes a support fixture, an ink jet print head having a plurality of nozzles, and an articulatable robotic arm. One of the support fixture and the print head are mounted to and carried by the robotic arm. The robotic arm is moveable so as to cause relative movement of the print head along a series of scanning paths that follow the surface contour of the curved surface of the article. A controller is coupled to the robotic arm and is configured to cause articulation of the robotic arm. The controller causes the robotic arm to continuously locate the print head relative to the curved surface and to cause the plurality of nozzles to eject printing medium at predetermined locations along the scanning paths so as to form the image.

Abstract: A method for printing on the curved surface of a three-dimensional (3-D) article, such as a plastic window. The printing method generally comprises generating a 3-D surface with the desired image; defining print head paths; calculating imaginary, two-dimensional printing surfaces; projecting the desired image onto the imaginary, two-dimensional printing surfaces; inspecting and correcting for any missed portion of the projected image; calibrating and adjusting the projected image; and printing the projected image through the imaginary, two-dimensional printing surfaces, thereby, creating the desired image on the surface of the 3-D article.

Abstract: An apparatus for printing an image onto a curved surface of a three dimensional article. The apparatus principally includes a support fixture adapted to support the article, an ink jet print head having a plurality of nozzles, and an articulatable robotic arm. One of the support fixture supporting the article and the print head is mounted to and carried by the robotic arm. The robotic arm has more than three degrees of freedom of movement and is moveable so as to cause relative movement of the print head along a series of scanning paths that follow the surface contour of the curved surface of the article. A controller is coupled to the robotic arm and is configured to cause articulation of the robotic arm so as to move the print head along the series of scanning paths. The controller causes the robotic arm to continuously locate the print head relative to the curved surface of the article in a position suitable for printing as the print head is moved along the series of scanning paths.

Abstract: An apparatus and method for printing a conductive grid onto a plastic panel, and a resultant product. A nozzle is mounted to the end of an arm, and the nozzle is coupled to a source of conductive ink. A flow regulator, coupled to the ink source, regulates the flow rate of ink out of the nozzle and is controlled by a controller. The controller is further configured to apply an initial conductive trace onto a panel and to apply a subsequent conductive trace beside or onto the initial conductive trace to vary the volume of the grid line along a portion of its length.
