    Abstract: A method and structure for a piezoelectric ink jet printhead. The method can include forming a piezoelectric composite from a liquid sol-gel solution. A first layer of the liquid sol-gel solution can be deposited onto a substrate using, for example, a spin coat process, wherein the substrate may be a printhead diaphragm. The first layer may be partially cured, then a second layer of the liquid sol-gel solution can be deposited onto the partially cured first layer, which is then partially cured. Any number of layers of liquid sol-gel solution can be deposited to result in a piezoelectric composite having a suitable thickness. Subsequently, all of the partially cured layers are fully cured. Printhead processing can continue to form a completed piezoelectric ink jet printhead.

    Abstract: A method for printing a three-dimensional crystalline structure such as a chocolate layer wherein, after printing, the material has a desired crystal structure and a plurality of non-random cavities. An embodiment can include printing a liquid first layer of material with a printer onto a second layer of material having a crystal structure. Subsequently, the printed liquid first layer is processed to solidify the first layer. During the processing of the printed liquid first layer, the second layer functions as a crystal seed layer through physical contact with the printed liquid first layer and the second layer crystallizes with the crystal structure. In some embodiments, confections may be formed from high-quality chocolate, where the confection has a reduced caloric content with acceptable mouthfeel. In other embodiments, a confection may have a previously unrealized mouthfeel and taste.

    Abstract: A printer includes a printhead configured to eject high viscosity material and refill a reservoir in the printhead with high viscosity material. The printhead includes a transducer having an electroactive element and a member to which the electroactive element is mounted. An electrical signal activates the electroactive element to move the electroactive element and the member in the reservoir of high viscosity material. This movement thins the high viscosity material and enables the printhead to eject the thinned material while refilling the reservoir. The apertures through which the thinned material is ejected share a common manifold without separate chambers for each of the apertures.
