How to Clean a 3D Printer Resin Tank

The Importance of Cleaning Your Resin Tank

As a seasoned 3D printing enthusiast, you know that maintaining your printer is crucial to ensuring optimal performance and longevity. One of the most critical components of your printer is the resin tank, which holds the liquid resin used to create your 3D prints. Over time, resin residue can build up inside the tank, leading to decreased print quality, failed prints, and even damage to your printer. That’s why it’s essential to regularly clean your resin tank to keep it in top condition.

What You’ll Need

Before we dive into the cleaning process, let’s review the tools and materials you’ll need:

  • Nitrile gloves
  • Isopropyl alcohol (IPA)
  • Microfiber or lint-free cloth
  • Plastic scraper or spatula
  • Safety glasses (optional but recommended)

Step-by-Step Cleaning Process

Now that you have your supplies, let’s get started with the cleaning process:

  1. Put on your nitrile gloves and safety glasses (if using).
  2. Remove the resin tank from your 3D printer and empty any remaining resin into a separate container.
  3. Inspect the tank for any solidified resin or debris. Use a plastic scraper or spatula to remove any stubborn residue, being careful not to scratch the tank’s surface.
  4. Dampen your microfiber or lint-free cloth with IPA and wipe down the inside of the tank, making sure to remove any remaining resin.
  5. Pour enough IPA into the tank to cover the bottom and sides completely. Let it sit for at least 5 minutes to dissolve any remaining resin.
  6. Use your plastic scraper or spatula to gently scrape any remaining residue from the tank’s surface.
  7. Drain the IPA from the tank and wipe it down with a clean cloth.
  8. Repeat steps 4-7 as necessary until the tank is completely clean.
  9. Once the tank is clean, let it dry completely before refilling it with resin and returning it to your printer.

Tips for Maintaining Your Resin Tank

Regular cleaning is essential, but there are a few additional tips you can follow to keep your resin tank in top condition:

  • Use a separate tank for each type of resin you use to prevent cross-contamination.
  • Store your resin tanks in a cool, dry place away from direct sunlight.
  • Replace your resin tank periodically, as recommended by the manufacturer, to ensure optimal performance.

Safety Precautions

While cleaning your resin tank, it’s essential to take proper safety precautions to protect yourself and your environment. IPA is a highly flammable substance, so it’s crucial to use it in a well-ventilated area and away from any open flames or heat sources. Additionally, always wear nitrile gloves to avoid contact with the IPA and any remaining resin residue. Safety glasses are also recommended to protect your eyes from any splashes or spills.


If you’re experiencing issues with your resin tank even after cleaning it, there may be a more significant problem at play. Here are a few common troubleshooting tips to help you get to the root of the issue:

  • Check for any cracks or damage to the tank’s surface. If the tank is damaged, it may need to be replaced.
  • Check the tension on the FEP film, which sits between the resin and the printer’s LCD screen. If the tension is too loose or too tight, it can affect print quality and lead to resin leakage.
  • Check the printer’s firmware and settings to ensure they’re up to date and correctly configured.

If you’re still having issues, it’s always a good idea to consult your printer’s manual or contact the manufacturer for additional support.

FAQs – How to Clean a 3D Printer Resin Tank

What is a 3D Printer Resin Tank?

A 3D printer resin tank is a container in which the liquid resin is poured into the printer for the printing process. It is usually made of a high-quality polymer that can withstand the exposure to the UV light used in the printing process and is resistant to the aggressive nature of the resin itself.

Why should I clean my 3D Printer Resin Tank?

Cleaning your 3D printer resin tank is necessary to maintain the quality of the 3D prints and the lifespan of the printer. The tank must be cleaned after each printing process to remove the excess resin and prevent it from hardening inside the tank, which can damage the printer. Also, cleaning the tank helps to remove any dirt or contamination that can affect the quality of the successive prints.

How often should I clean my 3D Printer Resin Tank?

The resin tank of a 3D printer should be cleaned after each printing process. This ensures that the tank is clean and ready for the next print job. Additionally, if the printer is not being used for an extended period, it is recommended to remove any remaining resin from the tank and clean it before storing.

What are the steps to clean a 3D Printer Resin Tank?

To clean a 3D printer resin tank, you must first remove any excess resin using a spatula or scraper. Next, remove the tank from the printer and rinse it with IPA (isopropyl alcohol) to remove any remaining resin. Then, gently scrub the tank with a soft-bristle brush to remove any dirt or contamination. After cleaning, rinse the tank again with IPA and dry it with a lint-free cloth.

Can I reuse the resin after cleaning the tank?

Yes, you can reuse the resin after cleaning the tank. However, it is essential to filter the resin through a strainer to remove any debris particles. It is also necessary to check the resin’s density and adjust it if needed before using it again for printing.

What precautions should I take when cleaning the resin tank?

When cleaning the resin tank, it is essential to wear protective gloves and eyewear. IPA is a hazardous substance and should be used in a well-ventilated area. Additionally, it is recommended to wear a respiratory mask to avoid breathing in the IPA fumes. Finally, avoid using paper towels or other materials that can leave fibers on the tank surface.
