Saturn Film vs Mars Build Plate
Release Film Material
The ELEGOO Saturn 10-Inch PFA Release Film 5-Pack uses PFA material for its release surface. PFA is a fluoropolymer known for high chemical resistance and durability. It withstands corrosive resins and high temperatures without degrading quickly. The ELEGOO Mars 4 Ultra Aluminum Build Plate does not use a release film in its primary construction. Instead, it relies on an oxidized black sandblasting laser-carved surface. This surface provides the necessary texture for resin adhesion and easy removal. Since one product is a film and the other is a solid metal plate, they serve different roles. The Saturn part is a consumable layer, while the Mars part is a structural component.
UV Transmittance
The Saturn PFA film boasts 92% UV transmittance. This high percentage allows light to pass through efficiently. Faster and more even resin curing results from this property. You get higher speeds and success rates with superior print quality. The Mars 4 Ultra build plate does not list UV transmittance specifications. It is made of aluminum alloy, which is opaque. Light must pass through the LCD screen and the release film to cure the resin. The build plate only reflects or absorbs light after the resin has cured. Therefore, the Saturn film directly impacts the curing process speed. The Mars plate does not influence UV transmission.
Build Plate Material
The Mars 4 Ultra build plate is constructed from aluminum alloy. This material ensures the platform is non-deformable with good flatness. It provides a stable and reliable surface for printing. The Saturn PFA film is not a build plate. It is a thin film that sits on top of the LCD screen. The Saturn film is transparent and measures 0.43 inches in height for the package. It does not provide the rigid support structure that the aluminum plate does. The aluminum plate supports the weight of the print. The film protects the screen. They are made of entirely different materials for different functions.
Surface Texture
The Mars 4 Ultra plate features a double-sided oxidized black sandblasting laser-carved surface. This texture increases model adhesion during printing. It also allows for easy removal of the printed model. The surface helps improve the overall printing success rate. The Saturn PFA film features a smooth, flawless surface. It is free of wrinkles, scratches, and bubbles. This smoothness minimizes the risk of print failures caused by uneven curing. The film prevents resin adhesion to the screen. One surface is designed for adhesion. The other is designed for non-stick release. Both textures are critical for their respective roles.
Chemical Resistance
The Saturn PFA film exhibits excellent resistance to corrosive chemicals. This is vital for resin printing, where liquid resins can damage materials. The film ensures reliable results in demanding conditions. It also resists high temperatures. The Mars 4 Ultra aluminum plate does not explicitly list chemical resistance specifications. However, aluminum alloys generally handle resin exposure well. The plate screws have end caps to prevent resin from flowing inside. This design feature aids in cleaning and post-processing. The Saturn film protects the LCD from chemical damage. The Mars plate protects the printer bed from deformation. Both offer protection, but the film explicitly highlights chemical resistance.
Choose the right ELEGOO part
Users wanting faster, higher success prints
The Saturn 10-Inch PFA Release Film offers 92% UV transmittance. This specification allows for faster and more even resin curing. The smooth, flawless surface minimizes wrinkles and bubbles. These factors lead to higher success rates and superior print quality. You benefit from effortless part release and reduced print failures every time.
Users needing stable, non-deforming build surfaces
The Mars 4 Ultra Aluminum Build Plate is made of aluminum alloy. This material ensures the plate remains non-deformable with good flatness. You get a stable and reliable platform for your printing needs. The double-sided oxidized black sandblasting surface increases model adhesion for higher success rates.
Users wanting easy cleaning and maintenance
The Mars 4 Ultra Aluminum Build Plate features screw end caps. These caps prevent resin from flowing inside the screws. This design ensures your build platform is easy to clean. You can remove printed models easily. The included Allen wrench allows you to replace or fasten screws as needed for maintenance.
