When choosing an ACF vs PFA 3d printer accessory, you need to match the film to your resin workflow. Both options offer 92% UV transmittance for consistent curing and non-stick surfaces that help models release easily. They share similar chemical resistance and durability traits. The main difference lies in the material structure and specific printer compatibility. ACF uses composite technology for faster printing with RAPID resin, while PFA is a general-purpose film for standard resin workflows.
Key differences

|---|---|---|
| Release Film Type | ACF | PFA |
| Dimensions | 290mm*195mm | not listed |
| Film Thickness | 0.3mm | not listed |
| Pack Quantity | 3 PCS | 5 PCS |
| Specific Compatibility | Saturn 3 Ultra | Saturn 2, 3, 4, 4 Ultra |
Which one should you choose?
Choose ELEGOO Saturn 3 Ultra ACF Film 3-Pack if
- You use RAPID resin and need faster printing cycles
- You want a thicker 0.3mm film for added durability
- You print exclusively on the Saturn 3 Ultra
Choose ELEGOO Saturn 10-Inch PFA Release Film 5-Pack if
- You need a film compatible with multiple Saturn models
- You prefer a larger pack of 5 films
- You want a transparent film for standard resin printing
Verdict: Choose the ACF film if you prioritize speed with RAPID resin and need the specific thickness and size for your Saturn 3 Ultra. The PFA film is a better fit if you need broader compatibility across several Saturn models and want more films in the package. Both provide reliable release and UV transmittance for high-quality prints.
ACF vs PFA Film Specs
Film Type
The primary difference between these two options is the material composition. Product A uses ACF release liner film, which ELEGOO describes as a composite technology. This design includes one frosted side and one smooth side to prevent adhesion to the LCD screen. Product B uses PFA film. While the specific composite structure is not detailed in the provided data, PFA is known for its exceptional non-stick performance and chemical resistance. Both types aim to provide a smooth, flawless surface free of wrinkles or bubbles, but the underlying material science differs, which may affect longevity and release characteristics in your specific resin workflow.
UV Transmittance
Both films share identical optical performance regarding light transmission. Product A specifies 92% UV light transmittance, ensuring faster and more accurate curing of the resin. Product B also boasts 92% UV transmittance, enabling faster and more even resin curing. This shared specification means that neither film will significantly slow down your print speed or reduce layer accuracy due to light blockage. You can expect similar curing efficiency from either option, allowing for consistent print quality regardless of which film you choose for your ELEGOO Saturn series printer.
Film Thickness
Durability during the peeling process is often linked to thickness. Product A has a specified overall thickness of 0.3mm. This dimension is designed to prevent the release film from breaking during printing, ensuring it withstands everyday use and maintains quality over time. Product B does not list a specific thickness value in the provided data. However, it is described as durable and resistant to corrosive chemicals and high temperatures. If film tearing is a concern for you, the explicit 0.3mm specification of Product A provides a clear metric for robustness that is absent for Product B.
Printer Compatibility
You must ensure the film fits your specific printer model. Product A is explicitly designed for the Saturn 3 Ultra, with dimensions of 290mm by 195mm. It is not stated if this film fits other models. Product B offers broader compatibility, supporting the Saturn 2, Saturn 3, Saturn 4, and Saturn 4 Ultra, as well as other 10-inch LCD 3D printers. If you own multiple ELEGOO machines or a different 10-inch brand, Product B provides more flexibility. If you strictly use a Saturn 3 Ultra, both options work, but Product B covers a wider range of devices.
Pack Quantity
The number of films included affects how long you can go between replacements. Product A comes in a 3-pack. Product B is sold as a 5-pack. Since both films offer similar chemical resistance and UV transmittance, the quantity becomes a practical factor for your supply chain. Having five films means you have more spares on hand, which can be convenient for maintaining a continuous printing schedule without frequent reordering. The difference in count is significant, giving Product B a clear advantage in terms of volume provided for your resin printing needs.
Which ACF or PFA Film Fits Your Workflow
Users with Saturn 3 Ultra needing speed
Product A is designed for the Saturn 3 Ultra. It supports faster printing with RAPID resin. The 0.3mm thickness prevents breakage during use. One side is frosted and the other smooth. This composite technology helps prevent adhesion to the LCD screen. You get three films in this pack.
Owners of Saturn 3, 4, or 4 Ultra
Product B works with Saturn 2, 3, 4, and 4 Ultra models. It fits other 10-inch LCD printers too. You receive five films in this pack. The surface is smooth and free of wrinkles. It resists corrosive chemicals and high temperatures. This option offers broad compatibility for various ELEGOO resin printers.
Buyers wanting more films per purchase
Product B includes five films in the package. Product A only includes three. Both offer 92% UV transmittance for even curing. Both resist chemicals and wear. If you need more replacements at once, the five-pack is the practical choice. The transparent film ensures clear visibility during printing.

Frequently asked questions
Can I use ACF film on a Saturn 4 printer?
No, the ACF film in this comparison is specific to the Saturn 3 Ultra. The product data lists it as a 3-pack for Saturn 3 Ultra only. If you have a Saturn 4, you should look for the PFA option, which is compatible with Saturn 3, 4, and 4 Ultra models.
Which film provides better chemical resistance?
The PFA film offers reliable chemical resistance. The verdict notes that this type prioritizes chemical resistance and surface quality. ACF film focuses more on high UV transmittance and durability for faster printing speeds. Both maintain non-stick surfaces, but PFA is the better choice if you are printing with aggressive resins.
How many films come in each pack?
The ACF option comes in a 3-pack. The PFA option is available in a 5-pack. The PFA pack size is larger, which may be better for users who go through films quickly. The ACF pack is smaller, suited for those who prefer thicker liners and less frequent changes.
Is the ACF film thick enough to prevent breakage?
Yes, the ACF film is 0.3mm thick. This thickness helps prevent breakage during the printing process. The product data highlights its durability for Saturn 3 Ultra users. This structural integrity supports faster print speeds without the film tearing under stress.
Does the PFA film have a frosted side?
The provided data does not specify the surface texture for the PFA film. It is listed as transparent. The ACF film, however, has one frosted side and one smooth side. If you need a frosted surface for adhesion control, the ACF film is the documented choice.
Which film is better for RAPID resin?
The ACF film is the right choice for RAPID resin. The verdict states it delivers high UV transmittance, which supports faster printing with this specific resin type. The PFA film prioritizes chemical resistance and part release ease over maximum UV transmittance, making it less ideal for speed-focused workflows.
