AI Verdict
This 0.15mm FEP film with 95% UV transmittance is for ELEGOO Mars 4, 5, and 5 Ultra users needing replacements.
This FEP film is a direct fit for specific ELEGOO Mars printers (Mars 4, 5, 5 Ultra) and offers high 95% UV transmittance for quicker curing. However, its 0.15mm thickness and high transmittance mean you'll likely need to recalibrate your resin exposure settings to prevent print failures or loss of detail.
If you want to avoid recalibration or prefer a different feel, look for FEP films with the exact same thickness and stated transmittance as your printer's original film.

Pros
- Compatible with ELEGOO Mars 4, Mars 5, and Mars 5 Ultra LCD 3D printers, fitting 206*146mm vats.
- Features 95% UV light transmittance, enabling faster resin curing.
- Constructed from wear-resistant and chemically resistant FEP material.
- Offers a non-stick, smooth surface to prevent resin adhesion and ensure easy model removal.
- Designed to be UV stable, resisting degradation over time.
- Can withstand over 60,000 releases, indicating extended durability.
Cons
- The 0.15mm thickness and high light transmittance may require recalibrating exposure settings, potentially leading to overexposure and reduced detail if not adjusted.
- Some users have reported FEP film failing prematurely, leading to resin spills and cleanup.
- Achieving correct FEP tension during installation can be challenging, with too loose or too tight leading to print issues.
- The film's thickness might differ from original FEPs, potentially affecting release force and print parameters.
Dimension Scores
The film's 95% UV light transmittance and smooth, wrinkle-free surface contribute to accurate and high-quality prints.
While the film itself is non-stick, the installation process requires careful tensioning and potential print setting adjustments, which can be challenging.
This FEP film is specifically designed for a narrow range of ELEGOO Mars printers (Mars 4, 5, 5 Ultra), limiting its application.
Elegoo claims the film can withstand over 60,000 releases and is wear-resistant, chemically resistant, and UV stable, though some users have reported premature failures.
Best For
- ELEGOO Mars 4, Mars 5, or Mars 5 Ultra owners needing a direct replacement FEP film.
- Users seeking faster print times due to the 95% UV light transmittance.
- Individuals who prioritize a non-stick surface for easier model removal and reduced print failures.
- Those looking for a FEP film with stated wear and chemical resistance for longevity.
Not Recommended For
- Users of 3D printers not listed as compatible (e.g., FDM printers).
- Beginners unwilling to recalibrate print settings after FEP replacement.
Watch Out For
- Expect to adjust your printer's exposure settings; one user needed to drop from 3.2s to 0.6-1s to avoid overexposure after installing a new FEP.
- Be prepared for potential premature film failure; one user reported their FEP giving out after just two days, resulting in a resin leak.
- Installation requires careful attention to tension; an FEP that is too loose can cause print adhesion problems.
- The 0.15mm thickness might be different from your printer's original FEP, which could subtly alter print performance.

What Buyers Say
This FEP film is a bit of a mixed bag, mostly because its high 95% UV light transmittance means you'll probably have to dial in your exposure settings again, sometimes drastically. One user had to cut their exposure time from 3.2 seconds down to less than a second to avoid overcuring. While it's generally praised for its non-stick properties and smooth surface, there's a concerning report of a film failing after just two days, leading to a messy resin spill. Getting the tension right during installation is also a common point of discussion, as it directly impacts print success.
“Look, it's FEP, it works, but seriously, check your exposure times after you put this in, I had to drop mine way down or everything was overcured. And watch out, one of mine ripped super fast, what a mess.”
Common Praise
- The film's non-stick surface helps models release easily from the vat.
- The smooth surface is free of wrinkles, scratches, and bubbles, which helps resin adhere evenly.
- The 95% UV light transmittance allows for faster resin curing.
- It's wear-resistant and chemically resistant, suggesting it holds up well to resin.
- One user found it worked better than their Mars 2 Pro's pre-installed FEP.
Common Complaints
- Requires significant recalibration of exposure settings, with one user needing to reduce exposure from 3.2s to 0.6-1s.
- One user experienced a FEP failure after only two days, causing a resin leak.
- Getting the FEP tension correct during installation can be tricky and impact print quality.
- The 0.15mm thickness might be different from previous FEPs, potentially affecting print parameters.
Ownership Tips
- You'll definitely need to run calibration prints and adjust your resin exposure settings after installing this FEP, as its high transmittance changes things.
- Keep an eye on the film for any early signs of wear or damage, especially if you're doing a lot of printing, as some have reported quick failures.
- Take your time with the installation to ensure proper tension; a phone tuner app can help get it right around 330Hz, though factory settings might be lower.
- Have IPA and cleaning supplies ready, just in case of a resin spill from a failed FEP.

Buying Guide
When you're buying FEP film for your resin 3D printer, you're essentially getting the clear bottom of your resin vat. This film is what the UV light shines through to cure your resin, and your print peels off of it with each layer. Its quality directly impacts how well your prints stick (or don't stick) and how clear the light passes through. You need to match the size and thickness to your printer, and be aware that a new film often means tweaking your resin exposure settings.

Alternatives
If this film doesn't fit your needs, look for FEP or PFA films with different thicknesses (e.g., 0.127mm for some Mars 3 Pro models) or specific light transmittance ratings that better match your original film or desired print characteristics.
