Do I Need to Empty the Resin Tank After Every Use?

Knowing when to empty your resin tank is key to maintaining the quality of your prints or castings. While frequent cleaning isn’t always necessary, some situations do require it for best results.

When Should You Empty the Resin Tank?

It’s not essential to empty your resin tank after every use, especially if you continue with the same resin type and regular project intervals. However, if you plan to switch to a different resin or expect a long pause before your next session, it’s wise to empty and clean the tank. This practice helps prevent cured residue, contamination, and colour mixing issues.

How to Clean and Store Your Resin Tank

Start by pouring leftover resin into a clean mixing bucket or a sealed container. Carefully wipe out any residue from the tank with a lint-free cloth. For stubborn or cured resin, use an approved cleaner such as isopropyl alcohol (99.9%) on a soft cloth—but avoid soaking silicone parts. Let the tank air dry before storing it in a dust-free environment to protect its surface.

Tips to Prevent Cross-Contamination

Use designated tools for different resin types to avoid accidental mixing.
Employ a graduated measuring cup for precise resin dosages and easy pouring.
Clean all tools and containers thoroughly after each project, especially when changing resin brands or colours.

When This Matters Most

If you’re producing items for display, sale, or functional use, maintaining a clean resin tank is crucial to prevent defects and ensure professional results. It’s especially important for projects requiring colour clarity and surface perfection.
