FEP/ACF Maintenance Guide
Introduction
FEP and ACF films are essential components of your resin printer. Damaged or dirty films can ruin prints and waste resin. Here’s how to care for them.
1. What Are FEP & ACF Films?
-
FEP (Fluorinated Ethylene Propylene) is the transparent film at the bottom of resin vats
-
ACF (Advanced Clear Film) is a newer variant used in faster, high-end printers
2. How to Clean
-
After each print, pour resin back into the bottle using a filter
-
Wipe film gently with IPA using a soft, lint-free cloth
3. When to Replace
-
If the film is cloudy, scratched, or punctured
-
If prints keep failing despite correct settings
4. Best Practices
-
Avoid using sharp tools near the film
-
Don’t leave resin sitting in the vat for days
-
Store spare films flat in a clean envelope
Conclusion: With proper care, your film can last dozens of prints. Regular maintenance ensures consistent quality and avoids failed jobs.
