Resin Mixer

Material that is left in the print tray between builds needs to be stirred periodically with the Resin Mixer. Refer to the Material Stirring and Curing Chart and/or your material's Instructions for Use for information on stirring print materials.

CAUTION: Failure to sufficiently mix materials 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 the recommended solvent.


  1. Run the mixer through the material, with the sharp end (1) facing down. Grip the mixer on the indented gripper (2). Do this for five minutes. Please see the images below for the proper stirring technique.
Do not move the Resin Mixer's blade across the print-tray film like a knife. Rather, move it up and down similar to using an ice scraper.

  1. Holding the mixer slanted, run it back and forth through the material, careful not to put too much pressure on the print-tray film. Do this for the time prescribed in the Material Stirring and Curing Chart.


CAUTION: Putting too much pressure on the print-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 print tray must be replaced.

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

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

CAUTION: Take care not to slosh material out of the print tray while stirring. If this happens, you will have to clean the parts of the printer that the material got on.

  1. After stirring, allow the mixer to drip material back into the print tray and then wipe excess material off the mixer with a nonabrasive cloth.

  2. Repeat this process before every print job.

CAUTION: Be sure to clean the mixer with IPA between uses. Failure to do so risks mixing unstirred material or different material in with material currently in the print tray.
