Metal Tank vs PFA Film Specs
Release film material
The ELEGOO Saturn 2 and 3 Metal Resin Tank comes with a pre-installed FEP release film. This standard film is functional but may require replacement sooner due to wear. In contrast, the ELEGOO Saturn 10-Inch PFA Release Film 5-Pack uses PFA material. PFA offers superior non-stick performance and chemical resistance compared to FEP. It prevents resin adhesion more effectively, ensuring easier part release. You get five sheets in the pack, providing a longer supply than a single FEP film. This material choice supports higher print quality by minimizing surface defects.
Build structure
The metal tank is constructed from anodized aluminum, making it durable for long-term usage. It includes a lid to protect against dust and UV light. The design features neat screws to fix the vat in place and feet on the bottom to keep the FEP film from touching your workbench. This provides a stable, rigid structure. The PFA film is just a thin, transparent sheet without any structural housing. It relies entirely on the existing printer vat for support. If you need a complete replacement assembly, the metal tank offers a robust, self-contained unit, whereas the film is just a consumable part.
UV transmittance
The PFA release film boasts 92% UV transmittance. This high transmission rate enables faster and more even resin curing. It leads to higher speeds and success rates with superior print quality. The metal tank includes a pre-installed FEP film, but its specific UV transmittance percentage is not listed in the provided data. Standard FEP films typically have lower transmittance than PFA. Therefore, the PFA film likely allows for more efficient curing cycles. You may experience shorter layer times with the PFA film compared to the standard FEP included with the metal tank.
Compatibility
The metal tank is designed specifically for the ELEGOO Saturn 2 and Saturn 3 resin 3D printers. It is sized for these models and works with all types of resin. The PFA film is compatible with a broader range of devices. It supports the Saturn 2, Saturn 3, Saturn 4, Saturn 4 Ultra, and Saturn 4 Ultra 16K models. It also fits other 10-inch LCD 3D printers. If you own newer Saturn 4 series printers, the PFA film is the only option listed. For Saturn 2 or 3 users, both products are compatible, but the film offers more versatility across different printer generations.
Durability and resistance
The anodized aluminum tank is built for durability. It resists physical damage and provides a long-lasting housing for your resin. The PFA film exhibits excellent resistance to corrosive chemicals and high temperatures found in resin printing. This ensures reliable results in demanding conditions. However, the film is a consumable item that wears out. The metal tank is a permanent fixture. You will likely replace the PFA film multiple times over the lifespan of the metal tank. The tank provides structural longevity, while the film provides chemical and thermal resilience during the printing process.
Choose the right ELEGOO tank or film
You want a complete replacement vat
This metal resin tank is a full assembly made of anodized aluminum. It includes a pre-installed FEP film and extra lid. The sturdy build protects your printer and keeps dust out. You get a ready-to-use vat that fits Saturn 2 and Saturn 3 models, ensuring proper alignment and stability for consistent prints.
You need long-lasting release films
This pack provides five PFA release films. PFA offers 92% UV transmittance for faster curing and better print quality. The smooth surface prevents wrinkles and bubbles, reducing print failures. It resists corrosive chemicals and heat, making it durable for demanding resin printing tasks across Saturn 2, 3, 4, and Ultra series printers.
You prefer standard FEP compatibility
The metal tank comes with a pre-installed FEP film. FEP is a standard release material that works with all resin types. The anodized aluminum body is durable for long-term use. This option is ideal if you want a complete unit with neat screws and feet to keep the film off the workbench.
You want to upgrade film quality
Upgrading to PFA films improves release performance significantly. The non-stick surface ensures effortless part removal. With high UV transmittance, resin cures more evenly and quickly. This 5-pack allows you to maintain high print success rates over time, supporting various Saturn models including the 10-inch LCD printers for superior results.
