AI Verdict
A 0.15mm FEP film for Mars 4, Mars 5, and Mars 5 Ultra printers, offering 95% UV transmittance and a non-stick surface.
This FEP film is specifically designed for the Elegoo Mars 4, Mars 5, and Mars 5 Ultra, matching their required dimensions (206mm*146mm) and thickness (0.15mm). Its high UV transmittance (95%) directly supports the printers' curing process, making it a direct replacement for maintaining print quality.
If you're constantly replacing FEP, look for nFEP or ACF films, which are often cited for longer lifespan or faster printing, though they might have different installation nuances.

- Offers good release performance, allowing for easy model removal without damage.
- Boasts durability for up to 60,000 cycles, extending replacement intervals.
- Resistant to corrosive chemicals and high temperatures encountered in resin printing.
Cons
- Installation requires careful tensioning to avoid print failures or film damage.
- Can be accidentally damaged during print removal if models stick too strongly.
- Potential for resin leaks onto the LCD screen if the film is damaged, requiring extensive cleaning.
- Some users report needing to adjust printer settings significantly after FEP replacement to achieve successful prints.
- The replacement process involves numerous small screws, which can be time-consuming.
Dimension Scores
The 95% UV light transmittance directly contributes to accurate curing and detailed print results.
While described as 'easy to install', the process of replacing FEP film typically involves disassembling the vat and carefully tensioning multiple screws, which can be fiddly for some users.
This FEP film is specifically sized for Elegoo Mars 4, Mars 5, and Mars 5 Ultra printers, limiting its use to these specific models.
The film is rated for up to 60,000 releases and is resistant to chemicals and high temperatures, indicating a longer lifespan compared to generic films.
Best For
- Owners of Elegoo Mars 4, Mars 5, or Mars 5 Ultra printers needing FEP film replacement.
- Users experiencing print adhesion issues or visible wear on their current FEP film.
- Individuals seeking to maintain optimal UV light exposure for precise resin curing.
Not Recommended For
- Printers not compatible with 206mm*146mm FEP film dimensions.
- Users unwilling to perform detailed installation involving multiple screws and tensioning.
Watch Out For
- Accidental FEP damage can occur when removing prints that stick too strongly, as reported by a Mars 5 Ultra user who damaged the FEP on their first test print.
- Incorrect FEP tension during installation can lead to print failures; one user found their nFEP was too tight initially after replacement.
- Resin leaking through a damaged FEP film can harden onto the LCD screen, necessitating careful scraping to avoid screen damage.
- Some FEP films come with a protective layer that, if not removed, can cause print problems.
- The FEP replacement process involves unscrewing and re-screwing up to 14 perimeter bolts and 18 smaller bolts, which can be fiddly.

What Buyers Say
While the product has a high rating of 4.6/5 from 89 reviews, specific detailed user feedback regarding complaints is not readily available from direct searches. However, general FEP film experiences suggest that proper installation and tensioning are critical to avoid print failures. Users have reported issues like prints sticking to the FEP, leading to accidental damage during removal, and the need to adjust printer settings significantly after replacement.
“Man, this FEP is okay, but I swear every time I change one, I spend an hour messing with screws and then another day trying to get my prints to stick right again. Why can't it just work?”
Common Praise
- Non-stick surface helps prevent resin from adhering to the film.
- High 95% UV light transmittance supports faster curing times.
- Smooth surface without wrinkles or bubbles ensures even resin adhesion.
- Good release performance makes model removal easier.
- Rated for a long lifespan of up to 60,000 cycles.
Common Complaints
- Prints sticking to the FEP, causing damage during removal.
- Difficulty achieving correct FEP tension during installation, leading to print issues.
- Resin leaks onto the LCD screen if the FEP is compromised.
- Needing to significantly adjust exposure settings after FEP replacement for successful prints.
- The installation process involves many small screws and can be time-consuming.
Ownership Tips
- You might need to reset the FEP counter in your printer's maintenance menu after replacement, though some users report printing successfully beyond the 60,000 layer guideline if no defects are visible.
- Careful cleaning of the resin vat and frame with IPA is crucial during replacement to prevent contamination.
- Applying PTFE lube or WD40 to the FEP is a common user trick to help prevent prints from sticking.
- The FEP film's tension is critical; too tight or too loose can cause print failures, and it might need to 'work in' over a few prints.
- Always check for and remove any protective films on new FEP sheets, as missing them can cause unexpected print issues.
Frequently Asked Questions
What printers is this FEP film compatible with?
This FEP film is compatible with the ELEGOO Mars 4, Mars 5, and Mars 5 Ultra resin 3D printers.
What are the dimensions and thickness of this FEP film?
The film measures 206mm*146mm and has a thickness of 0.15mm.
How does this FEP film affect print speed and accuracy?
It has a 95% UV light transmittance, which helps ensure faster and more accurate curing of the resin, leading to high-quality models.
How often should I replace the FEP film?
The film is rated for up to 60,000 cycles, but replacement frequency depends on printing volume and resin types. Replace it if you notice print quality decline, increased adhesion issues, or visible wear.
Is installation difficult?
Installation is described as quick and easy, but it involves disassembling the resin vat, carefully placing the new film, and evenly tightening multiple screws to ensure proper tension.
Buying Guide
When you're dealing with resin 3D printing, the FEP film is a consumable part that sits at the bottom of your resin vat. It's what separates your liquid resin from the UV light source and allows your prints to form. Over time, it gets worn, scratched, or even punctured, and you'll need to replace it to keep getting good prints. Getting the right size and thickness for your specific printer is non-negotiable.
Film Dimensions (206mm*146mm)
This is like the screen size on your phone; it has to perfectly match the opening of your printer's resin vat. If it's too small, resin leaks; too big, it won't fit right and can cause tension issues.
Thickness (0.15mm)
Think of this like the gauge of a guitar string. Too thick, and it might block too much UV light or be too stiff, affecting print release. Too thin, and it could tear easily. 0.15mm is a common balance for durability and flexibility in many resin printers.
UV Light Transmittance (95%)
This is how much UV light gets through the film to cure your resin. A higher percentage means more light reaches the resin, leading to faster curing and more accurate details in your prints, like a clear window letting in more sunlight.
Alternatives
If this film doesn't fit your printer, search for FEP films matching your specific vat dimensions and a thickness of 0.127mm to 0.15mm. For enhanced durability or faster printing, look for nFEP or ACF films compatible with your printer model.
