FEP film
From €23.00
A reliable optical-grade FEP film for resin 3D printers, designed to provide clear UV light transmission, smooth release, and consistent results across the vat.
It combines excellent optical clarity with low surface energy to help printed layers separate cleanly from the vat surface. This supports stable printing and reduces unnecessary stress on the model.
Choose FEP when you need a dependable, easy-to-handle replacement film for everyday LCD, DLP, and SLA resin printing. It is a high-quality universal option for miniatures, models, prototypes, and other resin printing applications.
The film is supplied in large pre-cut sheets with protective layers on both sides. It can be trimmed to the required size with scissors, making it suitable for a wide range of resin 3D printers and vat sizes.
Replace your FEP film when you notice scratches, dents, cloudiness, deformation, reduced print quality, or an increase in failed prints.
Key features
- OPTICAL-GRADE CLARITY. One of the clearest plastics for resin 3D printing available on the market. Provides excellent transmission of ultraviolet rays and visible rays. No significant light refraction or reflection.
- EXCELLENT RELEASE. FEP has the lowest surface energy of all plastic films. Displays excellent print release and anti-stick properties during printing.
- DURABLE. Resistant to high temperatures and chemically resistant to resin printing materials, making it suitable for regular, long-term use.
- UNIFORM THICKNESS AND CLARITY. Available in standard: 150 μm thickness. Provides consistent printing throughout the whole vat.
- LARGE, TRIMMABLE SHEETS. FEP film is pre-cut into 280 × 450 mm size sheets. The 280 × 450 mm sheet fits Sonic Mega 8K and all other smaller printers. One sheet can be cut into four 5.5-inch sheets with scissors.
- EASY TO HANDLE. Supplied as pre-cut sheets with protective film on both sides. Easy to cut with scissors to the required size.
Frequently asked questions
When should you replace your FEP film?
Replace the FEP 3D printing film if you notice visible scratches, dents, cloudy areas, resin leaks, deformation, poor layer release, or more frequent print failures. A worn or damaged FEP film can affect light transmission and layer separation, which may lead to lower print quality or failed prints.
How to replace FEP film?
- Always wear protective gloves to prevent skin contact with resin residue.
- Remove the resin vat and pour any remaining resin back into the bottle through a filter.
- Clean the vat with isopropyl alcohol (IPA) and allow it to dry completely.
- Unscrew the vat frame and carefully remove the old film.
- Remove any cured resin, dust, or residue from the vat and frame.
- Remove the protective layers from both sides of the new film. Place it flat over the frame without stretching it by hand.
- Refit the frame and insert the screws loosely. Tighten them gradually in a diagonal or cross pattern to distribute tension evenly.
- Place the frame back into the vat and tighten the remaining screws evenly. The film should become smooth and evenly tensioned.
- Carefully cut away the excess FEP around the outside of the vat using scissors or a sharp hobby knife.
- Fill the vat with a small amount of water and leave it on a paper towel for several minutes. Check for leaks, then empty and fully dry the vat before adding resin.
