Cleaning the SprintRay Pro S Resin Tank

Cleaning the SprintRay Pro S Resin Tank


Remove resin tank

To clean the tank, begin by removing the tank from its cradle in the printer.


Empty the tank

If there is any liquid resin left in the tank, pour it back into the original resin bottle through a mesh strainer to ensure no hardened chunks can contaminate your bottle. We recommend a standard paint filter of 200 microns or greater, though a finer mesh can still work. Make sure to do this quickly as the resin will begin to harden as soon as it is exposed to UV light!


Remove large resin chunks

If your tank has any partially-cured chunks of resin stuck to the bottom, peel them away gently. Take care not to use abrasive tools, as the bottom of the resin tank is extremely fragile.


Gently Wipe Inside of Tank

Using IPA 91% or greater, moisten your soft shop towels and gently wipe the inside of the resin tank, being careful not to apply too much pressure to the edges of the plastic film. Once clean, allow the resin tank to air dry for at least 15 minutes before refilling with resin, to prevent any potential contamination. Do not pour IPA directly into the tank as this can damage it.

Please Note: we do not recommend cleaning out tanks and adding a new type of resin. One tank per type of resin is the best way to ensure successful prints! If any two resins get mixed, it can lead to print failures -- especially if you then pour that mixture back into your original bottle. The best way to keep your printer running well for a long time is to maintain the integrity of your resin and your tank. Many customers have had success with using a label maker to add labels to their tanks including information such as the type of resin and the version number (Die & Model 1 vs 2, for instance).


Clean Underside Tank Glass

If any resin has been allowed to collect on the underside of the resin tank, clean with 91% or greater IPA, as well as a high quality glass cleaner, such as Windex. Hold a bright light (such as a flashlight or your smartphone flash) at a low angle and shine it across the surface to make sure you have cleaned all possible contaminants. If you see any colored streaks or lingering resin, clean the bottom again with the above procedure. Going slowly and methodically generally yields the best results!
