ELEGOO5PCs PFA Release Liner Film Saturn LCD 3D Printer 260 x 185 MM and 0.127mm Thickness with Stronger Release Functionality

For failing prints:Step one. Re flatten your build plate. Use two sheets of copy paper for a good starting thickness.Step two. Did you claibrate your resin? Not all screens/models have the same "brightness", so don't trust the suggested exposure times. Get a small calibration test and tune it using the suggested times as your starting point. Manufacturers suggest exposure on one resin was 2.5s. 3.2s worked best for me.Step three. Check your old FEP film for scratches. Lots of scratches? Dents? Replace. These are wonderful and last a long time as long as you're not scratching them and abusing them. I learned the hard way not to use paper towels to clean them when changing resin, even those will scratch the film. Don't use any tools to pry stuff off that's stuck to the film. Instead, press from the underside of the film and a corner should come off or the whole piece stuck to the film may pop off. I use a silicone head from a retired spatula for mixing resin in the resin vat to further protect the FEP film. I've only had to change one so far with almost no problems printing.

These are my tips to improve release film life. The tray shown is after at least 25 prints. I damaged it with a metal putty knife with very light pressure. Stupid, would have been good for more prints.1) Use a silicon edge squeegee to clear off the resin from the resin tray. This was a 6" wide squeegee that I cut down to 3". Two swipes and the tray is clean. Cut the squeegee to just the right width, do it in one swipe.2) WITH THE RESIN REMOVED, NEVER, EVER USE A TISSUE, PAPER TOWEL OR EVEN A MICROCLOTH TO WIPE THE TEFLON FILM. WITH or WITHOUT ISOPROPYL ALCOHOL (IPA).3) Use a squirt bottle to rinse the Teflon film, then swipe it off with the silicon edge squeegee. Air dry.4) After 5 or so 3D prints, ultrasonic clean the empty tray in IPA, air dry.5) Only use plastic tools to remove failed prints!

Exchanged this lining with existing lining on our 3d Tiger Printer and it works exactly the same. These sheets run a few bucks each while purchasing a new basin through the manufacturer costs us $126 each.

After several days of back and forth with Elegoo on whether I received the 2.0 FEP or 1.0 when I ordered the 2.0 we finally figured it out. Elegoo changed their 2.0 FEP name on the envelope to PFA. The naming is confusing but if you don't see the RED 2.0 on your Envelope but see PFA you have the new 2.0 version. Very confusing on Elegoo's part for no reason, but hope this help's with the mess I had to deal with.

The directions do not explain that each sheet is 3 layers. The two outer layers must be removed before installing
