Two tip wipe assemblies are located in the rear of the oven, one for model and one for support. Each assembly consists of a flicker and a brush. The tip wipe assemblies keep the printer’s tips and tip shields free of purged material debris and material buildup.
The tip wipe assemblies are mounted behind the purge chute and extend through the purge chute via two slots cut into the chute’s exterior.
After material is purged from a tip, the tip passes across the tip wipe assembly. The flicker cuts the purged material from the end of the tip and knocks it into the purge chute.
The brush cleans the tip and tip shield. Purged material debris is guided down from the tip wipe assemblies to the bottom of the oven chamber via the purge chute.
