    摘要： A printing system includes a housing, a track supported by the housing, and a cart which rides along the track. The printing system also includes print heads which eject material onto the cart. To prevent material from inadvertently accumulating on the track and the housing, the cart also includes a wiper configured to wipe the material from at least a portion of the housing. The printing system also includes at least one collection tray configured to direct and/or collect the material wiped from the housing. The printing system further includes a coating applied to outer surfaces of at least some of the elements of the housing, the track, and the cart to further prevent the material from inadvertently accumulating on the track and the housing. The coating can be a siloxyfluorocarbon coating.

    摘要： An appartus 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.

    摘要： A disconnect fitting adapted for use with a phase changing composition including a fitting base having a first fitting base end, a second fitting base end and a fitting base opening therebetween, a pin capture disposed within the fitting base opening, a displaceable pin secured within the pin capture, a fitting socket having a first fitting socket end, a second fitting socket end, a fitting socket opening therebetween, the second fitting socket end secured to the second fitting base end, and a valve at least partially disposed within the fitting socket opening. When the displaceable pin is in an unloaded condition, the displaceable pin extends in a direction of the second fitting base end, and when the displaceable pin is in a loaded condition, the displaceable pin is compressed in a direction of the first fitting base end. The pin capture permits passage of the phase changing composition through the fitting base opening when the displaceable pin is in the unloaded condition or the loaded condition. The disconnect fitting permits a secure connection of the fitting base and the fitting socket regardless of the state the material when the base and socket are disconnected.

    摘要： A maintenance system for maintaining a scalable printhead array comprises: a pair of tracks disposed in parallel and on opposite sides of a printhead array; a shaft extending between the tracks and configured to engage with each track to move along the tracks; a plurality of maintenance modules mounted in series along the shaft between the tracks and configured to move along the tracks with the shaft to perform maintenance operations on a plurality of printheads of the printhead array, the tracks being configured to guide the shaft and the plurality of maintenance modules along a path from a resting position to an operating position the printhead array and from which at least one of the plurality of maintenance modules performs a maintenance operation on at least one printhead of the printhead array; and an actuator configured to move the shaft along the tracks.
