Patent number: 7460921Abstract: A method and associated software and a system for automatic package marking makes use of specification of an image for a package. The specification includes specifications of data fields for marking on a package. Data values for the data fields are received from multiple data sources. Images are formed based on the received data values and the specification of the image.Type: GrantFiled: September 28, 2004Date of Patent: December 2, 2008Assignee: Markem CorporationInventors: Chris Sullivan, Simon Starkey, James Cupit, Jacob Harris

Publication number: 20080269940Abstract: Provided is a volume element printing system for printing a three-dimensional object. The system includes a first printhead group having a plurality of first printheads configured to print a first voxel layer on a substrate, and at least one second printhead group having a plurality of second printheads downstream from the first group. The second printhead group is configured to print a subsequent voxel layer on at least part of the first layer, said second printheads being reconfigurable as backup printheads for the first printheads in case of failure. The system also includes an object insertion device configured to insert an object into a cavity defined by the voxel layers, and a conveyor configured to convey the substrate past the printhead groups. Also included is a control system configured to control and monitor the printhead groups, the object insertion device and the conveyor, and dynamically to reconfigure the second printheads if failure of a first printhead is detected.Type: ApplicationFiled: July 14, 2008Publication date: October 30, 2008Inventor: Kia Silverbrook

Publication number: 20080269939Abstract: A method for building a three-dimensional object by depositing drops of material from a printing head onto a printing surface, layer upon layer is provided. The method includes providing data representing a layer of a three-dimensional object having X and Y coordinates, where X represents the direction of motion of the printing head; applying an X offset parameter for the X coordinate to compensate for inaccuracies caused by deviation of a drop flight trajectory between forward and reverse motions of the printing head; modifying the data based on the X offset parameter and printing the layer of the three-dimensional object according to modified data.Type: ApplicationFiled: April 15, 2008Publication date: October 30, 2008Inventor: Eliahu M. KRITCHMAN

Patent number: 7430731Abstract: Some embodiments of the invention are directed to techniques for electrochemically fabricating multi-layer three-dimensional structures where selective patterning of at least one or more layers occurs via a mask which is formed using data representing cross-sections of the three-dimensional structure which has been modified to place it in a polygonal form which defines only regions of positive area. The regions of positive area are regions where structural material is to be located or regions where structural material is not to be located depending on whether the mask will be used, for example, in selectively depositing a structural material or a sacrificial material. The modified data may take the form of adjacent or slightly overlapped relative narrow rectangular structures where the width of the structures is related to a desired formation resolution. The spacing between centers of adjacent rectangles may be uniform or may be a variable.Type: GrantFiled: January 3, 2005Date of Patent: September 30, 2008Assignee: University of Southern CaliforniaInventors: Adam L.

Patent number: 7416276Abstract: A method of printing a three-dimensional object is provided. The method comprises providing a plurality of stationary printhead layer groups, each layer group comprising at least one printhead for printing a respective layer of the object; conveying a partially-formed object past the layer groups; and simultaneously printing material from at least one printhead in each layer group, such that a plurality of different layers are printed simultaneously by the layer groups.Type: GrantFiled: February 15, 2007Date of Patent: August 26, 2008Assignee: Silverbrook Research Pty LtdInventor: Kia Silverbrook
