A purge station assembly for use in an additive manufacturing system, which includes a purge station having a base bracket, a slide mount slidably engaged with the base bracket, and a contact head configured to clean a nozzle tip of a print head. The purge station assembly also includes a mechanism, such as a cable line, operably attached to the slide mount that allows an operator to mechanically move the slide mount relative to the base bracket from a location that is remote from the purge station.

Remotely-adjustable purge station for use in additive manufacturing systems

A linear motor includes a rotor rotatable relative to a surrounding rotor sleeve and about a central axis. At least one opening extends between an inner surface and an outer surface of the rotor. An externally threaded leadscrew extends through the rotor and along the central axis. An internally threaded nut is located within and mated to the rotor so as to rotate with the rotor about the central axis and ride along the leadscrew. A first cavity is located between the nut and a first bushing set against the inner surface of the rotor and a second cavity is located between nut and a second bushing set against the inner surface of the rotor. The at least one opening in the rotor forms a passage between the first and second cavities and is defined between the sleeve and nut so as to communicate excess lubricant.
