FEP foils
FEP foil is an accessory designed for 3D resin printing. Whether your 3D printer uses an SLA, DLP or MSLA laser, all these 3D printers have in common the need for release film.

Smart resin 3D printing
The key to it, of course, is FEP foil. This key element in resin 3D printing acts as a translucent physical barrier between the liquid resin and the curing source. It must withstand the high temperatures required to cure the resin, as well as have good mechanical resistance, as any damage can lead to serious leaks into the device and its components. A significant exploitation factor is the spatula itself - scratching off the prints over time will mean that the foils will simply have to be replaced, because the resulting dents and unevenness affect the final quality of the printout. The FEP material is characterized by high chemical resistance and non-stick properties. Thanks to these advantages, it has practically become a standard for anti-adhesive films for resin printing.
Replacing the FEP film
Our transparent FEP sheet allows UV rays to penetrate the resin and cure it. Over time, however, the foil can get dirty, scratched, clouded or worse, pierced and it needs to be replaced. Undoubted signs that a replacement awaits us are deep scratches on the foil, haze visible to the naked eye to such an extent that you can't see through it clearly and the fact that resin prints do not adhere to the plate. Cleaning it with sharp tools will most likely cause more damage. A simple way to check if the FEP film has micro-scratches is to carefully hold it up to the light and pour isopropyl alcohol on it and put a paper towel under it - water will not work in this situation due to its surface tension . If you notice wet spots on the paper towel, your FEP has holes. The replacement requires certain safety measures - it is worth taking care of gloves, transparent safety glasses and a mask.
