It's inevitable. You've gotten your printer dialed in, you're printing like a pro, and your prints are coming out sharp and perfect every time. Then, out of the blue, prints start failing. You start getting noticeable layer lines or surface imperfections in your prints. Your once perfect prints are now not printing like they should. Maybe you notice that your FEP film has dimples or creases in the surface. Or, even worse, you begin noticing resin leaking onto your screen.
If you notice any of the above, its likely time to replace your FEP film.
The FEP film is the layer of clear plastic stetched across the bottom of your resin vat. It's purpose is to allow UV light through and provide a surface for each layer of your print to cure. The FEP film is held in place under tension and it is this tension that allows the film to maintain a smooth surface but also have some give to it to allow the print to peel away from the film when the build plate lifts up after each layer.
Resin 3D printers require periodic maintenance to continue producing top quality prints. And for many, replacing the FEP film will be the first printer repair they will have to do. The consequences of ignoring a FEP that needs to be replaced can be dire. In addition to poor print quality, a damaged or worn FEP can rupture causing resin to leak all over your printer and workspace. Not only is this a big mess, but it can also end up damaging or destroying your printer.
