Both products from ELEGOO support 10-inch LCD resin printers like the Saturn series. The main difference lies in the film type and packaging. One offers a complete metal tank with pre-installed FEP, while the other provides a multi-pack of standalone PFA films. You need to decide based on your printer model and replacement needs.
Key differences

Which one should you choose?
Choose ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP if
- You need a complete replacement resin tank for your Saturn 2 or Saturn 3.
- You prefer a durable anodized aluminum vat that protects the film.
- You want a unit with the release film already installed and ready to use.
Choose ELEGOO Saturn 10-Inch PFA Release Film 5-Pack if
- You require a high UV transmittance rate of 92% for faster curing.
- You are upgrading to Saturn 4 or Saturn 4 Ultra models.
- You need a bulk supply of replacement films for long-term maintenance.
Verdict: The metal tank with FEP is best for users needing a full vat replacement for older Saturn models. The PFA 5-pack suits those prioritizing high UV transmittance and needing spare films for newer 4-series printers. Your choice depends on whether you need a tank or just the consumable film.
FEP vs PFA Film Specs
film durability
The ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP uses an anodized aluminum vat that is durable for long-term usage. This metal construction helps keep the FEP film from making contact with your workbench via feet on the bottom. In contrast, the ELEGOO Saturn 10-Inch PFA Release Film 5-Pack boasts excellent resistance to corrosive chemicals and high temperatures. PFA is generally known for higher heat and chemical resistance than standard FEP. The PFA film ensures reliable results in demanding conditions, while the FEP setup relies on the metal tank for structural support. This makes the PFA option better for harsh chemical environments.
uv transmittance
Print speed and quality often depend on how much UV light reaches the resin. The ELEGOO Saturn 10-Inch PFA Release Film 5-Pack features 92% UV transmittance. This high percentage enables faster and more even resin curing, leading to higher speeds and success rates with superior print quality. The data for the ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP does not list a specific UV transmittance percentage. Without this spec, you cannot confirm if the FEP film matches the PFA film's light efficiency. The PFA film explicitly supports faster curing, giving it a clear advantage in this category.
packaging quantity
You need to consider how many films you get in the box. The ELEGOO Saturn 10-Inch PFA Release Film 5-Pack comes as a 5-pack, providing multiple replacements for your printer. The ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP includes one FEP film pre-installed on the tank. It also provides an extra lid to keep away dust and UV light, but it does not include spare films. If you print frequently, having five films ready is more practical than starting with just one. The PFA pack offers better value for ongoing maintenance.
tank construction
The ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP is made of anodized aluminum. This metal vat is designed for long-term usage and includes neat screws to fix it in place. It also has an extra lid to protect against dust and direct sunlight. The ELEGOO Saturn 10-Inch PFA Release Film 5-Pack is just the film itself, without a tank. If you need a complete replacement unit, the metal tank is superior. However, if you already have a tank, the film is all you need. The metal tank offers more structural components for protection.
surface quality
Print surface finish depends on the film's smoothness. The ELEGOO Saturn 10-Inch PFA Release Film 5-Pack features a smooth, flawless surface free of wrinkles, scratches, and bubbles. This minimizes the risk of print failures for high-quality results every time. It also boasts exceptional non-stick performance, ensuring effortless peeling and release of printed parts. The data for the ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP does not describe the surface texture or non-stick properties of the pre-installed film. The PFA film explicitly guarantees a flawless surface for better print outcomes.
compatibility
Both products support ELEGOO Saturn series printers. The ELEGOO Saturn 10-Inch PFA Release Film 5-Pack is compatible with Saturn 2, Saturn 3, Saturn 4, and Saturn 4 Ultra models, as well as other 10-inch LCD 3D printers. The ELEGOO Saturn 2 and 3 Metal Resin Tank with FEP is specified for Saturn 2 and Saturn 3 printers. It also mentions Saturn 3 Ultra and Saturn 4 variations in the options list. Both cover the core Saturn models. The PFA film explicitly lists Saturn 4 support, while the tank focuses on Saturn 2 and 3. This is a tie for general Saturn compatibility.
Which ELEGOO resin tank fits you?
Need a ready-to-print complete tank
This option includes the anodized aluminum resin tank with the FEP film already pre-installed. You get a complete unit with protective feet and a dust lid. It is ready to use immediately on your Saturn 2 or Saturn 3 printer without needing to buy separate film or assemble components yourself.
Want faster curing and high durability
This pack provides PFA films boasting 92% UV transmittance for faster and more even resin curing. The material offers excellent resistance to corrosive chemicals and high temperatures. It ensures effortless part release and minimizes print failures, making it ideal for demanding conditions and high-quality results on compatible 10-inch LCD printers.
Need spare films for multiple printers
You receive five transparent PFA films compatible with Saturn 2, 3, 4, and Ultra models. This bulk pack allows you to swap films easily when changing resin colors or when a film wears out. The smooth surface prevents wrinkles and bubbles, ensuring consistent print quality across multiple builds without frequent interruptions.
