FEP film (2 pcs) - CW1S

The FEP film (2 pcs) - CW1S by Prusa Research is an essential consumable for operating SLA/MSL 3D printers, specifically designed for the Original Prusa SL1 and compatible LCD-based devices. Unlike liquid resins, this is a mechanical component acting as a release layer between the resin vat and the print bed. This highly transparent FEP film (Fluorinated Ethylene Propylene) is characterized by exceptional chemical resistance to standard UV resins and excellent surface tension, which allows the first layer to adhere to the build plate without the printed object sticking to the vat. The film's mechanical properties are crucial for print quality: it provides the necessary flexibility for the peeling process (layer separation) while maintaining high tensile strength to prevent tears. This ensures precise details and smooth surfaces for miniatures as well as high stability for engineering parts. Installation is straightforward, requiring only the film to be stretched into the holder frame. Safety aspects include replacing the film upon mechanical damage to prevent resin leakage. Post-processing here refers to cleaning the frame and careful tensioning to avoid wrinkles. This film is suitable for all common standard resins, regardless of the application in dental, jewelry, or engineering fields.
