Maintaining clarity and eliminating obstruction in the path of the laser are essential to the Form 2’s best performance. The Form 2 is equipped with a glass optical window directly under the resin tank. This window helps seal the optical path and keeps dust from entering the inside of the printer. Occasionally, the outside of the optical window may need to be cleaned to remove dust.

1. Disengage the Wiper

Pull the wiper toward the front of the printer to release the wiper’s foot from the mount. Set the wiper aside, resting on the far right edge of the resin tank. Manually slide the wiper mount to the center before removing a resin tank.

2. Cover Resin Tank

Wear gloves and hold the tank by the front tabs, sides, or rim, to avoid getting fingerprints on the internal and external surfaces of the window.
Do not rub or scratch and do not allow resin on the underside of the tank.

3. Remove Build Platform and Resin Tank

Always remove the build platform before removing the resin tank to avoid dripping leftover material onto the optical window.

4. Dry Wipe

Use a lint-free cloth or paper towel, such as a microfiber cloth or PEC*PAD, to remove dust from the window.

5. Wet Wipe

Proceed with a wet wipe if the dry wipe does not clean the glass completely. Only use IPA to clean the glass surface as any cleaning solution may degrade the anti-reflective coating. If resin has dripped onto the window, use a small amount of IPA with the cloth or paper towel. Wipe slowly, pulling the cloth toward you moving from the left to the right side of the optical window until you have cleaned the entire surface.
After cleaning with a wet solution, wipe the glass surface again with a dry wipe to remove any streaks.


Avoid using cleaners or materials that could scratch or leave residue on the glass surface of the optical window.
