Clean Resin Tray

You must clean the resin tray if:

  • You believe the resin tray has foreign debris or partially cured print material in it.
  • You are using a different print material in the same resin tray.

Every time you remove the resin tray for any reason, you should also inspect/clean the catch tray, as in the section Clean/Replace the Catch Tray.

NOTE: The elevator must be at its upper limit and the print platform must not be in the printer during this procedure.

NOTE: Two iterations of this process tends to be enough for a fully cleaned resin tray. If you find that you need to repeat this process more than once, consider spending more time brushing the membrane/tray when soaked in >90% alcohol solvent.

NOTE: Avoid touching the bottom of the membrane during this procedure. If resin is observed on this surface, spot clean with >90% alcohol solvent by squirting/pouring solvent on the area with uncured resin. Finish by drying with compressed air. Do not touch Part-Cleaning Brush or any other tool to the bottom of the membrane.


  1. Push in the tension-arm release lever and lift tension arm.
  2. Using nitrile gloves and using both hands, slowly lift the resin tray out of the printer.

CAUTION: Take care not to hit the resin tray on the elevator arms, printer lid, or other printer components during removal.

  1. You may remove partially cured print material and debris from the tray in one of two ways (please only choose 1):
    1. Pour the contents of the tray over the tray corner into your hazardous waste container. The Resin Mixer may be used to guide print material and debris out of the tray.

      CAUTION: Do NOT use the Platform Scraper to clean the resin tray, as it will easily puncture the resin-tray membrane.


    2. Rather than discarding the print material, you may also choose to keep this print material in its bottle. Use a glass funnel or solvent-resistant plastic funnel, along with a 190 micron automotive paint filter, to pour the print material back into its ORIGINAL bottle. When the tray is almost empty, use the plastic resin mixer to guide the last bits out. Discard the filter, as well as the cured print material it picks out, according to all government regulations.

      CAUTION: Do not pour print material into any bottle other than the one it came in. This is for two reasons: 1. The bottle has been designed to safely store resin without evaporation or curing inside; and, 2. You must scan the barcode on your bottle every time you print. Failure to scan the correct bottle will result in the machine storing incorrect levels of material remaining, as well as making it impossible for 3D Systems to track the material use should any print material issues arise.


  1. Place resin tray in its garage.

TIP: You may place a paper towel or clean-room wipe on your cleaning surface, so as not to get print material and/or solvent directly on it. This can also prevent foreign debris from dirtying or puncturing the tray's membrane. If you use this tip, be sure to discard the paper towel/wipe after each cleaning.


  1. There are two different cleaning solvents you might use in this step, depending on which material was in the resin tray:

    1. For any material EXCEPT for Figure 4 RUBBER-BLK 10: Pour approximately 250 mL of >90% alcohol into resin tray and use the Part-Cleaning Brush to gently agitate the material on the membrane and tray edges.

    2. If cleaning Figure 4 RUBBER-BLK 10 out of the tray: Pour approximately 250 mL of Propylene Carbonate into resin tray and use the Part-Cleaning Brush to gently agitate the material on the membrane and tray edges. RUBBER-BLK 10 has some material components that do not dissolve in >90% alcohol. Do not use >90% alcohol for this step.

  2. After brushing all surfaces that were in contact with resin, discard dirty solvent according to all government regulations.

  3. Rinse the resin tray with clean >90% alcohol solvent and discard solvent according to all government regulations. It is okay to use alcohol for RUBBER-BLK 10 in this step.



  1. Dry membrane gently with 30 psi dry compressed air using an air gun attachment, or allow tray to air dry.


  1. If uncured print material remains within the tray, repeat steps 5-8.
  2. If uncured print material remains on the outer edges of the resin tray:
    1. Wipe clean with a lint-free paper towel soaked with >90% alcohol (~15mL). Dispose of used paper towels and gloves discard according to all government regulations.
    2. Dry membrane gently with 30 psi dry compressed air using an air gun attachment, or allow tray to air dry.



  1. Inspect the resin tray to ensure no uncured resin and/or foreign debris remain.


  1. Discard all paper towels/wipes used throughout this procedure according to all government regulations.

The resin tray can now be stored in the Resin-Tray Garage or filled with new resin for printing.


You can also store the resin tray in the printer with the cover from the garage on top, as seen below.
