Mixing Material in the Resin Tray

Print material 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 Material Stirring and Curing Chart for information on stirring materials.

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

CAUTION: Ensure that the comb is clean before each use. To clean the comb, wipe it with a nonabrasive cloth and the recommended solvent (depending on the material it stirred before).

 

  1. Run the mixer through the material, 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 material, careful not to put too much pressure on the resin-tray film. Do this for the time prescribed in the Material Stirring and Curing Chart, or until all material that has stuck on the resin-tray film has been scraped off. You are looking for stuck-on material spots like that which is circled below:

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

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 print material 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 items that have been in contact with liquid material.

CAUTION: Take care not to slosh material out of the resin tray while stirring. If this happens, you will have to clean the parts of the printer that the print material got on.
  1. Repeat the stirring process as indicated by the Material Stirring and Curing Chart.

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