    Abstract: 3-D printers include a transfuse station having at least one roller on one side of an ITB supporting the ITB, and a transmission device on the same side of the ITB. A charge neutralizer is included on a second side of the intermediate transfer surface. The charge neutralizer outputs an opposite charge to neutralize existing static charge on a layer of the build material and the support material on the ITB, before the layer reaches the transfer station. Additionally, the intermediate transfer surface transfers the layer to a platen each time the platen contacts the second side of the intermediate transfer surface, at the transfer station, to successively form layers of the build material and the support material on the platen. Also, the transmission device outputs acoustic waves to cause the layer to move from the intermediate transfer surface to the platen, or to the layers on the platen.

    Abstract: A printing system for forming three-dimensional objects includes two laterally spaced rails, each of the rails have an internal cavity extending through the rail along a longitudinal axis. The printing system further includes two heating devices, one heating device is connected to the internal cavity of one of the two laterally spaced rails and the other heating device is connected to the internal cavity of the other of the two laterally spaced rails to enable each heating device to heat a surface of the rail in which the heating device is positioned. The printing system further includes a platform configured to move along the laterally spaced rails. The printing system also includes at least one of a pair of scrapers, wiper pads, and wiper blades mounted to the cart.

    Abstract: An apparatus detects inoperative inkjets during printing of three-dimensional objects. The apparatus includes an optical sensor that generates measurements of a height, a diameter, and a position for test dots formed on a substrate with material ejected from a printhead. These measurements are analyzed to detect inoperative inkjets to enable printhead maintenance at appropriate times to maintain the operational status of the inkjets in the printhead.

    Abstract: An apparatus detects inoperative inkjets during printing of three-dimensional objects. The apparatus includes an optical sensor with a predetermined focal plane. The optical sensor is moved to a position that enables the sensor to generate image data of material drops ejected by a group of inkjets in a single row of a printhead. These image data are analyzed to detect inoperative inkjets to enable printhead maintenance at appropriate times to maintain the operational status of the inkjets in the printhead. The optical sensor is moved along a length and width of the printhead to enable the sensor to generate image data of all the inkjets that eject material from the printhead.

    Abstract: A fuser fluid composition is disclosed, including a non-fluorinated functional silicone fluid, and a non-fluorinated non-functional silicone fluid, where the non-fluorinated functional silicone fluid is present in the fuser fluid composition in an amount of from about 1 wt % to about 30 wt % based on a total weight of the fuser fluid composition, and the non-fluorinated non-functional silicone fluid is present in the fuser fluid composition in an amount of from about 50 wt % to about 99 wt % based on a total weight of the fuser fluid composition. The non-fluorinated functional silicone fluid may include an amine-functional group. A cleaning web and a fusing subsystem for a printing system may include a material impregnated with the fuser fluid composition.
