6.6.4 Cleaning the slider
The slider is mounted on top of the Light Processing Unit (LPU) housing and allows for smooth
movement of the LPU housing across the flexible film interior. The slider also houses the glass
optical window. A clean slider protects the flexible film and preserves print quality. For detailed

Skin irritant: Resin and solvent may cause skin irritation or an allergic skin reaction.
Wear gloves when handling liquid resin, resin-coated surfaces, or solvent. Wash skin
with plenty of soap and water.
Required supplies
Isopropyl alcohol Non-reactive nitrile gloves PEC*PADs or low-fiber paper
towels
To clean the slider:
1. Put on a new, clean pair of nitrile gloves.
2. Add a small amount of clean isopropyl alcohol to a PEC*PAD or low-fiber paper towel.
3. Wipe the PEC*PAD or paper towel across the slider to remove any dust or debris that
has accumulated. Do not wipe the dust or debris into the printer cavity containing the
glass optical window.
If dust or debris has fallen onto the glass optical window, use compressed air to clean in and
around the glass optical window to avoid scratching it. If the glass optical window is smudged,
refer to section
6.6.5 Cleaning the glass optical window .
6.6.5 Cleaning the glass optical window
The glass optical window is embedded in the slider and mounted on top of the Light Processing
Unit (LPU) housing. During a print, laser light from the LPUs passes through the glass optical
window and into the resin tank. A clean glass optical window preserves print quality. For
