FEP Film

FEP and PFA (nFEP) films may start to have signs of wear and tear after printing for a while. Once it has major signs of wear and tear, dents, deformation, or piercings, it may be time to replace it. There are a few conditions that indicate that the FEP or PFA (nFEP) film requires replacing, these signs include:

  1. Severe dents, bumps, and scratches.
  2. Too cloudy.
  3. Loss of tension.
  4. Pierced.
To check for holes in the FEP or PFA (nFEP) film, pour some alcohol into the resin vat and place a paper towel underneath it. If you notice any wet spots on the paper towel, it may indicate the presence of holes in the film. This simple test can help you identify potential issues with the film and take necessary measures to address them.

If your model falls into the resin vat, or resin tank, during the printing process, please use a yellow plastic scraper to check for solids. Don’t leave the remaining cured resin in the resin vat.

DO NOT use the metal scraper to scrape up cured resin. 

After printing, gently use a soft scraper to scrape cured resin off the FEP or PFA (nFEP) film. If this doesn't work, use your fingertip to push the bottom of the FEP or PFA (nFEP) film, as shown in the GIF down below.

This will create a separation between the FEP or PFA (nFEP) film and the resin. Then use the scraper, or use your hand while wearing a glove, to pick up the cured resin. 

Once the resin hardens, it will become difficult to clean the FEP or PFA (nFEP) film, leading to a reduction in the FEP or PFA (nFEP) film’s overall lifespan.     

If you're struggling with prints that stick to the building plate, we recommend checking out our guide on how to avoid this issue. Click here to learn how.


Why does it happen?

We would like to let you know that this issue occurs due to static electricity being generated within the enclosure causing the resin to splatter. If the surrounding weather is dry, this phenomenon takes place. This happens because air holds less moisture at colder temperatures than warm and humid in the summer. Moisture assists in conducting electrical charges, so a lack of moisture in the air creates the perfect environment for static electricity to build and make the resin splash inside.

 FEP film, PFA (nFEP) film, and ACFare all transparent sheets that allow UV light to pass through, facilitating the easy curing of resin. These films are attached to the resin vat, serving as the surface for printing the resin 3D model. Depending on the frequency of usage, all three films may need to be replaced periodically.


What’s the Difference Between the Three?

The ACF (Advanced Composite Film) is a newly introduced resin printing film that surpasses the previous PFA (nFEP) and FEP options. With a smoother surface and reduced suction force, the ACF film offers superior performance, resulting in a higher success rate for resin printing, particularly with fast-curing resins.


When seeking support for your printer, you may be asked to provide the printer's serial number. The serial number uniquely identifies your printer and can be used to confirm warranty coverage, troubleshoot issues, and order replacement parts.


To locate the serial number on your printer, simply look for the white label on the rear of the device. On the label, you should see a combination of uppercase letters, numbers, and barcodes.


Remember to keep this information safe and accessible, as it will be useful if you ever need to seek support or service for your printer.

In order to slice your files using the Sonic Mighty 12K Upgrade Kit with the Chitubox Slicer, we would recommend you to follow the steps in the guide below:

1. Open Chitubox

3. Click on Add option.

4.  Go to Phrozen and choose Mighty 8K

5.  Here you can rename your printer to Mighty 12K or any other name as per your choice.

6. Uncheck "Lock Ratio".

7. Change the X and Y Resolution to the following values:

X: 11520 px

Y: 5120 px

8. You are all set to start slicing your model and print with your new Mighty 12K Upgrade Kit.



Note: Please make sure to select the resin type and adjust the print parameters based on the resin you are using.

Post processing

Once you’re done printing, remember to filter out excess resin. Don’t leave excess resin in the vat as this might lead to solids forming within the liquid which will affect the printing process.  

Step 1: Please filter out the excess resin using a funnel.

Step 2: Preserve the resin in an opaque plastic bottle. Do not store new resin and used resin in the same container.

Step 3: Store your opaque plastic bottle in a plastic zip-lock bag to reduce exposure to air.

Step 4: Make sure to preserve resin at a room temperature of roughly 15°C ~ 35°C or 59°F ~ 95°F in a dry environment and avoid sunlight.

After removing your 3D model from the building plate, the prints must be cleaned, washed, and post-processed thoroughly. The following guide includes two washing methods: the dunk and wash method and the Ultrasonic Cleaner method.

The Dunk and Wash Method

Step 1: Fill two basins with Phrozen wash or 95% alcohol, IPA.

Step 2: Rinse your 3D model in each basin and rinse for roughly 1 minute. Continue to wash the model until its surface is clean.

You may use a soft brush and lightly brush the model for better results. However, a toothbrush is not recommended as it may cause scratches on the 3D print.

Step 3: Once it’s done, place the 3D model to dry in a shaded area for 30-60 minutes before moving onto the post-curing process. You can also use a compressed air gun to fasten the process.

Step 4: After ensuring the 3D model is dry, you can now move onto the post-curing process.

DO NOT immerse your models for long periods of time into sanitizing alcohol, as this may cause models to break.

The Ultrasonic Cleaner

The Ultrasonic Cleaner is one of the most efficient ways for cleaning 3D prints. In the following guide, we will demonstrate the process of using the Phrozen Ultrasonic cleaner, which is currently available in our official store.


Step 1: Fill one basin and the Phrozen Ultrasonic Cleaner with Phrozen wash or 95% alcohol, IPA.

Cleaning liquids may become flammable and could evaporate fast, so please make sure you do not use the heating function. Make sure to operate the device within sight.

Step 2: Rinse your 3D model in the basin for roughly 1 minute in several rounds. This is to remove any uncured resin left on the model.

Step 3: Once it’s done, turn on the switch placed behind the Phrozen ultrasonic cleaner

Step 4: On the front panel, switch the left ON/OFF to OFF.

Step 5: The right indicates how long the machine is active. Set the timer for at least 30 seconds but below 3 minutes.


Washing with Phrozen Ultrasonic Cleaner

Step 1: Carefully place your 3D model into the basket of the Ultrasonic Cleaner.

Step 2: Turn ON the device by pressing the ON/OFF button on the right of the front panel.

Cleaning liquids may become flammable and could evaporate fast, so please make sure you do not use the heating function. Make sure to operate the device within sight.

Step 3: Once the cleaning process is over, switch off the Ultrasonic Cleaner, and then remove the model from the basket.

Step 4: Place the 3D model to dry in a shaded area for roughly 30-60 minutes before moving onto the post-curing process. You can also use a compressed air gun to fasten the process.

Step 5: After ensuring the model is dry, you can now move on to the post-curing process.

After cleaning, make sure to store the cleaning liquid in an airtight container and avoid exposing it to direct sunlight.


Why is Post Processing Important?

After every printing session, prints need to go through the washing and post-curing process. It is extremely important to know how to post-process your resin 3D prints. In this post, we will be sharing the ideal cleaning liquids that will maximize the quality and strength of your prints.


What Can I Use to Clean My Resin 3D Prints?

While 95 % Isopropyl Alcohol (IPA) and Ethanol Alcohol are our top recommendations for washing resin 3D prints, detergents such as Phrozen wash, Resin Cleaner can also be used to wash your resin 3D prints.

  • For the Water-Washable series, you can use water to clean your models.
  • For other Phrozen Resins you will need to use 95% alcohol or other detergents to rinse off your models. 

Burnout is the process of melting the Wax-like Castable Resin and letting it drain out from the mold. In order to produce a quality casting, we recommend the following burnout schedules below. Do note that these schedules are exclusive for Phrozen Castable Resins, including:

  1. Phrozen Castable Dental Resin
  2. Phrozen Castable Jewelry Resin
