How to Upgrade Your nFEP Film to ACF Film?

The new Phrozen ACF film is designed with a non-stick and smoother film surface for more efficient 3D printing. Compared to FEP and PFA (nFEP) film, the ACF film features a better release, significantly reducing the printing time and increasing success rate.

Before Installing the New ACF Release Film

Before starting this tutorial, there are two things you need to know:

1. This tutorial can also be a reference for Sonic Mighty 8K and/or other resin 3D printers that use a similar type of resin vat.
2. To protect your 3D printer from damage and reduce print failures, we recommend using Isopropyl alcohol (IPA) or 95% sanitizing alcohol to remove any residual resin on the film.

You can also read our warranty policy for ACF film.

How to Remove the Old PFA (nFEP) Film

Step 1: Clean the entire resin vat with Isopropyl alcohol (IPA) or 95% sanitizing alcohol. Please clear out the junction between the screws thoroughly.

Step 2: Use the 3 mm Allen wrench to remove the 4 corner screws. Then use the 2.5 mm Allen wrench to remove the remaining screws on the bottom.

Step 3: Put the resin vat aside and flip the metal frame.

Step 4: Use the 2 mm Allen wrench to remove all the remaining screws.

Step 5: After removing all screws, the metal frame can be removed. Remove the old PFA (nFEP) film from between the metal frames.

How to Install the New ACF Film

Step 1: Use 95% sanitizing alcohol to clean up the residual resin on the resin vat. 

Step 2: Put the ACF film on a table and slowly peel off the protective film. When installing the new film, make sure that the glossy surface of the ACF Film is going to be in the resin vat, while the matte surface will face the LCD screen.

Step 3:  Install the new ACF film in the following order:

1. One of the metal frames.
2. The new ACF film with glossy surface on top.
3. The other metal frame.

Step 4: Use the 2 mm Allen wrench to tighten the 8 screws in the corners diagonally. Then tighten the rest of the screws. You can also poke the ACF film with Allen keys before tightening the screw, so it’s easier to screw in.

How to Install the New ACF Film Onto the Resin Vat

Step 1: Install the new ACF film onto the resin vat according to the following sequence:

1. Turn the resin vat upside down
2. Place the new ACF film with metal frame and make sure that the matte surface is facing up.

Step 2: Use a  3 mm Allen wrench to tighten the 4 screws on the corners of the vat diagonally.

Step 3: Then, use the 2.5 mm Allen wrench to tighten the rest of the screws diagonally. Make sure all the screws have been installed properly.

Step 4: Make sure to cut off any excess ACF film around the vat. 

Step 5: Your ACF film replacement is now complete!

Congratulations!

You've complete the installation of your new ACF film. Now you are ready for faster and more stable printing ! You can also watch the tutorial video here for more visual demonstration:
