摘要： 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.

摘要： 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.

摘要： 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.

摘要： A maintenance method for a three-dimensional printer includes operating a platform to move along a second track past a first position where the second track is coupled to a first track, and along the first track in a process direction to a position opposite an ejector head positioned opposite the first track. The method operates the platform to (1) perform an operation on the ejector head positioned opposite the first track, (2) move the platform along the first track to a second position that is past the ejector head in the process direction, and (3) operates a switch to selectively couple the first track to the second track at the second position. The method also operates the platform to move past the second position to enable the platform to return to the second track.

摘要： A latch apparatus for retaining a flexible circuit cable within a receptacle mounted on a circuit board comprises a latch body having a second planar side comprising opposing alignment pins positioned at a first edge and a second edge of the body. A second end of the body comprises alignment protrusions extending from the second end in a first direction. The second end also comprises clamping protrusions extending from the second end in the first direction. The clamping protrusions are a distance from the alignment protrusions equal to a thickness of the circuit board. A latch member extends from the second end. The latch member comprises a linear clip surface extending from the latch in a direction perpendicularly away from the second planar side, and the linear clip surface runs in a second direction and has a length less than a width of the receptacle.

摘要： Devices and methods for a setscrew device. An elongated cylindrical rod has a first threaded portion with a first diameter and a continuous spiraling thread, an unthreaded shank portion with a second diameter, and a second threaded portion having the second diameter and a continuous spiraling thread. The second diameter is smaller than the first diameter. The unthreaded shank portion is located between the first threaded portion and the second threaded portion forming a step. A bias element is disposed on the step and surrounds the second threaded portion. A compression element is threaded onto the second threaded portion and operatively connected to the bias element.

摘要： An optical sensor enables a level of reflective fluid to be detected. The optical sensor includes a prism mounted at one end of a housing. The prism has an exterior surface that is parallel to the end of the housing and a width that corresponds to a width of the end of the housing. A photoemitter and a photodetector are mounted at another end of the housing to enable light emitted by the photoemitter to be reflected by the prism when the prism contacts reflective fluid and to enable light emitted by the photoemitter to pass out of the sensor when the prism is in contact with air.
