Pros
- Includes 6 FEP films, providing multiple replacements for extended use.
- Features 95% light transmission, which is crucial for accurate UV curing.
- Designed with non-stick and low friction properties to aid print release.
- Comes with protective films on both sides to prevent scratches before installation.
- Compatible with a wide range of popular LCD 3D printers, including ELEGOO Mars series and Photon Mono.
Cons
- The 0.15mm thickness might be too thick for some printer models or specific print settings, potentially causing print failures.
- Requires careful, even tightening during installation to prevent wrinkles and print issues.
- FEP film is a consumable that degrades over time and with use, requiring periodic replacement.
- Some users report that standard FEP film, like this, may not offer the same release performance as newer '2.0' or nFEP alternatives.
Dimension Scores
The 95% light transmission and non-stick properties meet the standard requirements for resin 3D printing.
While instructions are included, the FEP film replacement process itself requires careful handling and precise tensioning, which can be challenging for new users.
The film's dimensions (140 x 200mm) and stated compatibility cover a wide array of popular resin 3D printer models.
FEP film is inherently a consumable that degrades with use and can be easily damaged, making its durability average for the material type.
Best For
- Resin 3D printer owners needing multiple FEP film replacements for common printer models.
- Hobbyists and small-scale businesses looking for a cost-effective FEP film supply.
- Users who are comfortable with the FEP film replacement process and proper tensioning.
Not Recommended For
- Users seeking the absolute longest-lasting or lowest-stick FEP film alternatives like nFEP or PFA.
- Beginners who are intimidated by the precise installation process required for FEP film.
Watch Out For
- The 0.15mm film thickness has been reported by some users to be problematic for certain printer calibrations, leading to failed prints.
- Improper or uneven tightening during installation can cause the film to wrinkle, leading to immediate print failures.
- Forgetting to remove the protective films on both sides before installation will prevent UV light transmission and cause print failures.
- FEP film can be easily damaged by spatulas or failed prints, leading to leaks and requiring immediate replacement.

What Buyers Say
Many users find this KOYOFEI FEP film to be a functional and cost-effective replacement for their resin 3D printers. The inclusion of 6 sheets is a recurring point of satisfaction, offering good value. However, some users have noted that the 0.15mm thickness might be a bit much for certain machines, potentially requiring adjustments to print settings or leading to adhesion issues. The installation process, while guided by included instructions, demands precision to avoid wrinkles and ensure proper tension, a common hurdle for many. The protective films are a thoughtful addition, but forgetting to remove them is a common mistake that causes immediate print failures.
“Dude, these FEPs are fine, you get a bunch for the price, but seriously, make sure you pull off those protective films and tighten them down like a drum or your prints are gonna be trash. I had to re-level after changing it, too.”
Common Praise
- The 6-pack provides a substantial supply of replacement films, offering good value.
- Films arrive with protective layers on both sides, preventing scratches before use.
- The film's non-stick surface contributes to successful print separation.
- The 95% light transmission supports accurate curing of resin.
Common Complaints
- The 0.15mm thickness can be too much for some printers, causing prints to fail or stick.
- Installation requires careful, even tightening to prevent film wrinkles and print issues.
- FEP film wears out and needs frequent replacement, which is an ongoing cost and effort.
- Some users find the films prone to damage from failed prints or cleaning tools.
Ownership Tips
- You'll probably go through these faster than you think, especially if you have failed prints that puncture the film.
- The 'instructions on the packaging' are helpful, but watching a video on FEP replacement makes a huge difference for getting the tension right.
- Always keep a spare on hand; a punctured FEP can leak resin onto your LCD screen, which is a much bigger problem.
- The 0.15mm thickness might require slightly different exposure settings or lift speeds compared to thinner films.

Buying Guide
When you're buying FEP film for your resin 3D printer, you're essentially getting the transparent bottom of your resin vat. This film lets the UV light cure your resin while allowing your print to peel off cleanly. It's a consumable part, meaning it will wear out, get cloudy, or get punctured over time. You'll need to replace it periodically to keep your prints looking good and prevent resin leaks.
Dimensions (140 x 200mm)
This is the physical size of the film. You need to match this to your printer's resin vat frame, otherwise, it won't fit or won't cover the print area properly.
Thickness (0.15mm)
The thickness affects how much the film flexes during printing. Thinner films generally release prints easier but can be less durable. Thicker films are more robust but might require more force to release, potentially causing print failures if your printer isn't calibrated for it.
Light Transmission (95%)
This number tells you how much UV light passes through the film. A higher percentage means more light reaches the resin, leading to more accurate and consistent curing of your layers.
Alternatives
If you're looking for FEP film that lasts longer or has even better release properties, search for 'nFEP film' or 'PFA film,' but expect to pay more.
