Abstract: Embodiments of the present disclosure generally relate to droplet ejecting additive manufacturing systems used in the manufacturing of advanced polishing articles. In particular, embodiments herein provide methods for aligning a plurality of dispense heads of the additive manufacturing system. In one embodiment, a method for aligning a plurality of dispense heads of an additive manufacturing system includes forming an alignment test pattern comprising droplets dispensed from each of the plurality of dispense heads, comparing the placement of one or more of the droplets to determine offset distances therebetween, and generating one or more timing offsets based on the offset distances. In some embodiments, the method further includes using the timing offsets to control the dispensing of droplets from one or more of the plurality of dispense heads in a subsequent additive manufacturing process.

Abstract: A robotic positioning system that cooperates with a sensing system to correct robot motion is provided. The sensing system is decoupled from the sensors used conventionally to control the robot's motion, thereby providing repeatable detection of the robot's true position. In one embodiment, the positioning system includes a robot, a controller, a motor sensor and a decoupled sensor. The robot has at least one motor for manipulating a linkage controlling the displacement of a substrate support coupled thereto. The motor sensor is provides the controller with motor actuation information utilized to move the substrate support. The decoupled sensor provides information indicative of the true position the substrate support that may be utilized to correct the robot's motion.
