  "field": "Additive manufacturing and 3D printing",
  "definition": "A transparent thermoplastic film, abbreviated as FEP, used as the non-stick bottom surface of the resin vat in mask stereolithography (MSLA) and digital light processing (DLP) 3D printers. Its key properties are high UV light transparency and a low-friction surface, which allows newly cured layers to peel away cleanly with minimal force during the printing process. The FEP film is a consumable component that requires periodic replacement when it becomes clouded, stretched, or damaged.",
