Inspect Printer Lid

Inspect Dust Seals

There are strips of dust-sealing material around the underside of the printer lid. These strips must remain intact to avoid dust and other debris entering the print chamber. There are seven strips in total, as indicated below. If ANY of these strips is damaged or removed, cease printing until the strip is replaced. print-lid-dust-sealers.jpg

Inspect Printer Lid for Damage

Ensure that there is no damage to the printer lid that could hinder the printing process. Normal scratches are okay. Look for:

  1. Cracks in the lid's plastic. Any cracks could expose the printing area to ambient UV light, which could affect part quality and could also cure material in the resin tray.
  2. Breaks that do not allow the lid to close completely. If the lid does not fully close, the printing area could be exposed to ambient UV light.
  3. Breaks that do not allow the lid to stay open when lifted. This type of break will make many print processes more difficult and prone to error.

If any of these conditions is found to exist, contact 3D Systems Service for replacement information.

Clean Lid

The printer lid is made of acrylic and 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. NEVER use window-cleaning fluids with ammonia (such as Windex or Formula 409), gasoline, denatured alcohol, carbon tetrachloride, or acetone, which will cause the acrylic to crack. It is best not to have a print platform or resin tray installed during lid cleaning, so as not to contaminate either with the cleaner you are using.

  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 clear, clean water.
  3. Blot-dry with a chamois, damp cellulose sponge, or microfiber cloth to prevent water spotting

NOTE: Grease, oil, and tar may be removed with a good grade of hexane, naptha or kerosene. Be sure to wash these solvents off quickly to prevent damage to the acrylic.
