Reddit reviews FEP Film for UV 3D Printers | 0.2mm Thick | 4-Sheets | 280mm x 200mm Per Sheet | HD Optical Grade | Available in 3 Thicknesses

Was the model printed where the wrinkles formed? Because the lost details were probably due to that. I’ve never had the wrinkling issue but it seems like it’s due to the film not bing tight enough (Just guessing). Is the film tight, like if you tap it is it almost like a drum? First I’d try printing stuff on the edges where it’s not wrinkled and see what happens. If you still are receiving sup par results you can weigh the pros and cons of tightening the film. I would try this as a last resort as it may just make your film useless and have to buy more. If you do try to tighten the film use this official video by anycubic ( https://m.youtube.com/watch?v=DLi3chV43LQ ) I’m thinking that when you replaced the film you may have used a cap that was too big thus leaving you with excess film. I used the cap from a bottle of isopropyl alcohol and kept it under the film until I had all the screws done sandwiching the two pieces of metal. If you have to buy new film I’d recommend this from amazon ( https://www.amazon.com/gp/aw/d/B07GRSGQN6?psc=1&ref=ppx_pop_mob_b_asin_image) you get 4 sheets for $20 which I think is cheaper than buying official anycubic stuff. I use it myself and it seems to work well (haven’t used it very much)

(Edit: I’d also recommend making the figure more vertical. That may make the details better. If that doesn’t work I’d try adding 1 second to the normal layers. Use use the light supports as opposed to medium and heavy since your print is small. But you may have to add some supports, the auto support isn’t always accurate (use auto but then add what’s needed). One thing I’m not sure is necessary or not but every time I print I re level my plate and don’t turn the machine off until I print to ensure that the print is level (doesn’t look like that was your problem though). Lastly, the thing about your resin hardening in the bottom of the vat can easily be fixed if you move your printer to a spot not exposed to sunlight.
Hope this helps, update me if it does or doesn’t

I just did a tear-down of my printer last night and replaced my FEP for the first time. I too had resin on my screen. I was able to remove 99% of it by carefully dropping iso on the screen where the resin was and letting it sit for a bit until it started to really evaporate. I then took a plastic scraper and very, very, very gently scraped the resin off. Wiped off remaining iso, then took windex and got it nice and clean and shiny.

As for FEP, I just installed this FEP last night, but I didn't have time to try out my handiwork, but I can update when I run a print today. I can say that I went with the 200 micron thickness and it was a pretty tight install--I think if I go with this again I am going to go with 150 or even 100 micron thickness.

I picked up a pack of the FEP Film for UV 3D Printers from The 3D Club on Amazon. You get 4 sheets, but you can cut them in half for 8 sheets for $19.95. Saw a review on these for the Photon so I decided to try them, haven't had the chance yet, however.
