¶ Overview
After replacing the resin, a small amount of the previous resin may remain in the Automatic Feed System. This guide provides instructions to minimize cross-contamination between different colors or types of resin.
¶ Required Tools
- 300–400 ml IPA
- 300–400 ml new resin
¶ Procedure
¶ Method 1: Flushing the Automatic Feed System with New Resin
This method will consume some resin but effectively reduces the risk of color bleeding or cross-contamination
- Thoroughly clean any residual resin from the automatic feed tank and resin vat using IPA. Allow the tank and vat to air dry completely.
- Pour 300–400 ml of new resin into the automatic feed tank.
- On the touchscreen, start a print job to load the resin into the vat.
Once the print job begins, the resin will automatically load into the vat. Cancel the print before the LCD screen starts exposing
- On the touchscreen, tap Recycle Resin.

- Repeat the cycle several times (Start Print → Wait for resin to load into vat → Confirm pump has stopped → Tap Recycle Resin) until the Automatic Feed System are fully cleaned.
The resin used for cleaning the feed lines can still be used for printing on other machines, though minor color contamination is possible.
¶ Method 2: Cleaning the Automatic Feed System with IPA
-
Thoroughly flush any residual resin from the automatic feed tank and resin vat using IPA. Allow the tank and vat to air dry completely.
-
Pour 300–400 ml of IPA into the automatic feed tank.
-
On the touchscreen, start a print job to load the IPA into the vat.
-
Once the IPA has been loaded into the vat, cancel the print job.
-
Tap Recycle Resin on the touchscreen to return the IPA to the automatic feed tank.
-
Repeat the cycle multiple times (Start Print → Wait for IPA to load into vat → Cancel Print → Tap Recycle Resin). Afterward, pour out the IPA from the automatic feed tank.
-
With the automatic feed tank empty, run the pump one final time by tapping Recycle Resin to allow any remaining IPA to fully evaporate before resuming normal use.
