7.1.5 Clean Upper-Build-Chamber Door

This section assumes you have either shut down or disabled the Printer you are inspecting.
Because it is made of acrylic, the upper-build-chamber door requires special cleaning instructions that must be followed to
avoid damage and printer downtime. Inspect the door for material splashes and dust/debris (particularly on the inside of the
door).
Clean Acrylic Door
This door must be cleaned with a specialty product such as Novus No. 1 or Brillianize. A mild solution of soap or detergent and
water can also be safely used. DO NOT use window-cleaning fluids with ammonia (such as Windex or Formula 409), gasoline,
denatured alcohol, carbon tetrachloride, or acetone. Using any of these will cause the acrylic to crack.
1. Apply the cleaning product with a damp, nonabrasive, lint-free cloth. Using a microfiber cloth or cellulose sponge is also
acceptable.
2. Rinse with a nonabrasive cloth and clean water.
3. Blot-dry with a chamois cloth, damp cellulose sponge, or microfiber cloth to prevent water spotting
4. Remember to clean both sides of the door.
5. In rare cases, the door can acquire a static charge, which can attract material to its surface. Material can also splash onto the
door if a failed build falls off the platform and into the resin tray. If there is material on the door, follow Steps 1-4, above,
and then wipe down the door with an anti-static cloth to dissipate any charge that might be there.
Note: Grease, oil, and tar may be removed with hexane, naptha or kerosene. Be sure to wash these solvents
off quickly to prevent damage to the acrylic.

7.1.6 Clean the Touch Screen and Keyboard

1. Ensure that the Controller's touch screen does not have material, dust, or other debris on it. Inspect the touch screens on
the Printers, as well. The Controller/Printer should be powered off to prevent accidental touch interaction.
a. If it has dust or other debris on it, used compressed air and/or a microfiber cloth to clean it.
b. If it has material on it, pour EtOH or IPA on a nonabrasive cloth and spot clean; finish with an overall wipe down with a
fresh cloth and IPA.
2. Ensure that the Controller's keyboard does not have material, dust, or other debris on it. Before cleaning, ensure that the
keyboard is powered off.
a. If it has dust or other debris on it, use compressed air and/or a microfiber cloth to clean it.
b. If it has material on it, pour EtOH or IPA on a nonabrasive cloth and spot clean; finish with an overall wipe down with a
fresh cloth and IPA.
