    摘要： An additive manufacturing system has a plurality of manifolds in an extruder. Each manifold is connected to at least one nozzle of the extruder to enable the at least one nozzle to extrude thermoplastic material through a corresponding aperture in a faceplate mounted to the extruder. A plurality of valves is configured between each manifold and each nozzle connected to the manifold to enable the nozzles connected to a manifold to extrude thermoplastic material from the manifold selectively. The faceplate is also configured for rotation about an axis perpendicular to the faceplate to enable different orientations of the nozzles in the apertures of the faceplate. The different manifolds of the extruder enable a plurality of thermoplastic materials having a different property to be extruded simultaneously so the materials can join to one another while the materials are at an elevated temperature.

    摘要： A method for compensating for inoperative ejectors in a three-dimensional object printer has been developed. A printer detects an inoperative ejector in a printhead. The printer identifies functional ejectors that print at locations adjacent to locations where the inoperative ejector fails to print a drop. The printer modifies firing signals for the functional ejectors so those ejectors print drops having an increased drop volume at the locations adjacent to locations where the inoperative ejector fails to print a drop. The printer prints a first layer of material drops using the modified firing signals. The printer advances the printhead in the cross-process direction between layers so that locations where the inoperative ejector fails do print a drop do not coincide between layers.

    摘要： 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.

    摘要： An aqueous inkjet printer is configured to evaluate and adjust multiple components within the printer with reference to image data of the surface of a rotating member obtained at different times during a single print cycle. The print cycle can be performed in a multiple pass manner to enable a single optical sensor to be used for generation of the image data. Alternatively, the print cycle can be performed in a single revolution of the rotating member and multiple optical sensors positioned about the rotating member to generate the image data.
