ELEGOO 5PCS PFA Release Liner Film for Saturn 2/8K/3/4/4 Ultra/4 Ultra 16K Resin 3D Printer 273x176mm, 0.127mm Thickness with Stronger Release Functionality and 92% Light Transmittance

Works great with the Elegoo Saturn 3 ultra. Easy to use and easy to understand instructions on which side is which.

**edit** This was user error. I'm updating to 5 stars. I was overexposing by ~1.5 seconds and causing excessive adhesion to the PFA. I was using a bad calibration model for the particular resin I was using. These sheets perform as they should and they do have the best packaging of any brand of release film I've ever used. Keeps them flat, clean and protected while in storage. I have gone through 5 sheets from two orders in the last week. I am getting insanely high peel force with loud pops and printer jumping on each layer, even when curing only 1sqcm region. Saturn 4 16k, used an 80mmx80mmx8mm spacer when changing out the sheet each time. Did this product recently change? Did I just get a bad batch? These sheets have worked fine for me in the past. Pulling my hair out trying to figure out what the issue is. Curing at 4.5seconds per layer, resin is heated to 30c, I ran calibration tests, 3.5 seconds was definitely underexposed, so there's no way I'm massively overexposing, and again, very loud pops with even with very small cure area.

The release film worked flawlessly, but the operator did not🤦 Make sure the film is even when you put the first layer of screws in, and after you tighten the 2nd layer screws, the film will be taut and good! When you get a chunk of resin stuck on it, use a plastic scraper, or you will be replacing your film again. Seems obvious in hindsight, but the nicely sharpened metal scraper is quite effective in cutting the film. You'd THINK that it'd be even more obvious after you cut the stock film, but that would be incorrect. Sigh. I've made 20 prints with this (the 3rd) film with no tearing

The sheets do the trick, but sometimes I wish the trick was easier. If pre-identified whole point and easy to pierce points existed, these sheets would be perfect. Also, maybe put a remove me sticker on both sides of the film or you will have fun undoing all your work. Regarding functionality and print quality, these sheets are fine, no issues of yet. They seem to be very durable and the seal is tight. Worth the price, but really only if you get the larger pack, you will need them eventually anyways.

Works as intended, east to install.

5/5 I have to admit im a bit of an Elegoo Fan boy. Love their line up of printers and products. These are perfect for replacing the release liner after a failure in the cold winter.

Works well

Very good protector, if you see bubbles after you fix it, dont worry about it, it doesnt effect the print at all
