A probe for an additive manufacturing system includes a probe body having a first air port therethrough between an inlet and an outlet, and a location sensing probe extending from the probe body. The location sensing probe includes a probe end and a probe bar, the probe bar coupled between the probe body and the probe end, and a channel surrounding the probe bar, the channel having an inner tube having an inlet proximate the probe body and an outlet proximate the probe end. A method of determining a position of an item being printed in an additive manufacturing system, includes probing the position with a location sensing probe having a resolution finer than a print resolution of the print head.

A 3D printer includes at least one consumable loading bay configured to supply filament from a consumable supply assembly to a print head and at least one drive assembly that is configured to advance filament to the print head from the consumable supply. Each drive assembly includes a follower wheel rotatable about a follower axis and a drive wheel spaced apart from the follower wheel. The drive wheel is rotatable about a drive axis and is located on an opposing side of a filament path from the follower wheel such that the follower axis and the drive axis are substantially parallel. The drive wheel further includes an outer surface extending between two ends and has at least one engaging portion that is configured to engage with the filament and at least one disengaging portion that is configured to disengage from the filament.

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.
