Resin Mixer

Resin that is left in the resin tray between builds needs to be stirred periodically. In this case, you would use the Resin Mixer to stir the resin, as seen below. Refer to the section Premix Resin Before Cartridge Installation for information on how long to stir the resin.

CAUTION: Failure to sufficiently mix resins before each build may result in color deviation and/or print failure.

CAUTION: Ensure that the mixer is clean before each use. To clean the mixer, wipe it with a nonabrasive cloth and Isopropyl Alcohol (IPA) or Ethanol (EtOH).


  1. Run the mixer through the resin, with the sharp end (A) facing down. Grip the mixer on the indented gripper (B). Please see the images below for the proper stirring technique.

CAUTION: Do not scrape the mixer's blade from side to side like a knife. Rather, move it back and forth like an ice scraper.


  1. Holding the mixer slanted, run it back and forth through the resin, careful not to put too much pressure on the resin-tray film. Do this for the time prescribed in the section Premix Resin Before Cartridge Installation, or until all resin that has stuck on the resin-tray film has been scraped off. You are looking for stuck-on resin spots like that which are circled below:


  1. After stirring, allow the resin mixer to drip resin back into the resin tray and then wipe excess resin off the resin mixer with a nonabrasive cloth. Clean the resin mixer with IPA or EtOH after each use, so as not to contaminate another resin tray with a different resin type.
  1. Repeat the stirring process as indicated in the section Premix Resin Before Cartridge Installation.

CAUTION: Putting too much pressure on the resin-tray film can dent or puncture the film, rendering the tray unusable. The film cannot be replaced by itself; if the film is damaged, the whole resin tray must be replaced.

CAUTION: Puncturing the resin tray will force a full tray's worth of resin into the catch tray. Use extra caution when handling a full catch tray.

CAUTION: If the resin tray gets punctured, discard it in the same way you would other materials that have been in contact with resin.

CAUTION: Take care not to slosh resin out of the resin tray while stirring. If this happens, clean the parts of the Printer that the resin got on.
