Weekly Maintenance

Cleaning the Oven Chamber

The purge chute is designed to guide purged material debris from the tip wipe assemblies to
the bottom of the oven chamber for disposal. Purged material debris then collects within the
bottom of the oven chamber, beneath the platen. Do not allow excess material debris to
accumulate in the oven chamber as this could cause damage to the printer. Clean the oven
chamber on a weekly basis to remove build material debris and dust. A standard vacuum can
be used to clean this area if needed. If excessive accumulation occurs vacuum the oven
chamber as needed.

Cleaning the Platen

The steel platen provides the level surface on which parts are built (see
platen overview). A substrate is securely affixed to the platen by the substrate ejection handle.
If debris collects on the platen, it can adversely affect substrate adhesion.
1. Remove the substrate from the platen.
• Push down on the substrate ejection handle to release it from the platen.
• Slide the substrate from the platen.
2. Carefully remove purged material debris that have fallen into the openings of the platen.
• A standard vacuum can be used to clean the platen.

Monthly Maintenance

Clean/Inspect Tip Wipe Assemblies

The tip wipe assemblies should be cleaned once a month. While cleaning the assemblies,
inspect the flicker/brush assemblies for wear and replace as necessary when wear is detected.
Once material is purged from a tip, the flicker portion of the tip wipe assembly passes across
the tip's opening, cutting purged material off in small segments. The brush portion of the tip
wipe assembly then passes across the tip's opening cleaning the tip and its tip shield. As a
result, the flicker will wear at the location where the tip contacts its surface and eventually
develop a notch large enough for the tip to completely pass through the flicker; a notched
flicker cannot properly cut purging material. Similarly, material can become embedded within
the bristles of the brush resulting in clumping; clumped bristles cannot properly clean a tip or its
tip shield. The tip wipe assembly should be replaced once a significant notch develops within
Warning: Hot Surface Hazard
Always wear proper heat protective gloves and clothing when handling items inside
the oven, as surfaces within the oven can be very hot.
