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.
