Sovol 3D 5pcs Upgraded FEP Film Release Film with Holes Pre-drilled for Sovol 2021 Upgraded Version Resin Vat (with Only 1 Steel Ring), 200 x 140 x 0.15mm

These are my go to FEP films for my anycubic resin printer. Far fewer issues with sticking and botched prints.

Previously bought the sovol tank (which leaked and ruined my LCD) thought that the factory FEP was the issue. These are the recommended sheets for this Vat... leaked again! Messaged Sovol last week and have not responded.

Good quality FEP film. Its nice that the holes are pre-punched. I have purchased multiple times.

I Purchased these at the same time I purchased their vat for the Anycubic Mono 4K. I found out the hard way that you need to have spare FEPs on hand after the original got a hole in it and covered my screen with resin. They appear to be a perfect fit for their after-market vat. Only time will tell how they hold up to printing. Additionally, I plan on taping one of these over the LCD to prevent resin from curing on the LCD screen.

So it's nice to have pre-punched (and thusly pre-tensioned) FEP, but there's two gripes I have with this particular product:1. This fits Sovol vats, which have a 10-bolt pattern. Most 'Photon-like' vats have an 8-bolt pattern, so these replacement films only fit Sovol's aftermarket vat. I have both kinds in my lab, so now I have to stock two different films, or go back to manually tensioning and punching bulk film on the Sovol vats.2. The FEP quality isn't that great. Yes, I've removed the protective sheet from the FEP. Yes, both of them. There is a very audible ripping/pop sound during the raft layers, and I've replaced the film twice in the last dozen prints due to parts sticking to the film and not being removeable without damaging the FEP. It's fairly random if a print will succeed or not due to this. Yes, my bed is leveled.In short, is it nice to have pre-punched films? Absolutely, I'd just like an nFEP or something else with better survivability and lower maintenance.
