    Abstract: An additive manufacturing system and method for improving the certainty of removing or etching excess substrate from a stack of printed substrate slices to arrive at a 3D object. The approach includes printing a pseudo image as a shell layer around a desired object slice with less polymer (e.g., thermoplastic) material than the 3D object solid layer slice. This slows the etching process when this pseudo image is reached. The pseudo image may be printed to surround the object polymer image on a printed substrate sheet as a shell that provides notice during the excess substrate removal/cleaning process that the desired polymer image is nearby and extra care must be taken to avoid removal of the desired polymer image. The pseudo image may have a 3D patterned surface that can be recognized by a person doing the sandblasting or recognized automatically by an automated 3D object finisher.

    Abstract: A pin actuated printhead includes an orifice through which a material is ejected, a chamber to hold the material to be ejected, a channel connecting the chamber to the orifice, and an actuated pin, to enter the orifice and to eject the material from the orifice. The printhead is configured to eject a material with a viscosity of 10,000 cP or more at an elevated temperature.

    Abstract: An electrostatic ink jet printhead having an electrostatic actuator with improved resistance to adverse effects resulting from misalignment of a body layer to a gap standoff layer. In an embodiment, first and second portions of the gap standoff layer each have a first width and first and second sections of the body have each have a second width that is wider than the first width. Even with an amount of misalignment, the first and second sections of the body layer define nodes for an actuator membrane, thereby maintaining an effective width (WE) of the actuator membrane that is equal to a target width (WT) of the actuator membrane.
