EPAX nFEP Film Sheet 200 x 140mm Thickness 0.125mm for E6/X1 and Other 5.5/6 inch UV Resin 3D Printers, Pack of 3 Films

I bought a Phrozen Sonic Mini 4K and all the research I had done prior to buying the printer pointed to the factory FEP being the cause of many printing issues, so I decided to immediately upgrade to nFEP. These EPAX E6 sheets fit the Sonic Mini 4K perfectly and performance has been stellar. I havent had any resin sticking to the sheet and there is no popping sound when the build arm pulls away from the vat while forming the base-layers. Ive heard that these sheets can last quite a long time as well. Im still on my first sheet and have about 60hrs of printing on it so far; the surface still looks good - some fine micro-scratches from cleaning but overall performance is still perfect.

Using this for almost a year and its works great!

NFEP has more flex and better adhesion resistance. This makes changing the film easier since you dont have to worry about tensioning the film correctly. I just slapped it on and tightened it down and it works perfectly every time!

Got this for my Mars Pro and I dont get FEP stick issues anymore. The only time I get minis stuck to this is when I mess up the supports.

[UPDATES AT THE BOTTOM] [If you see this review on Youtube posted by Lisa Woods, DO NOT CLICK ON ANY LINKS. That is a scammer/bot/asshole copying Amazon reviews.] Got around to installing this on an Elegoo Mars 3D printer a few days ago, Ive printed several almost-full plates with no issues. No need to clean or aerate the film between sessions. Re-level and find Z Home again if this sheet is a different thickness than your old FEP. The usual SUCCC-POP! peeling sound heard when the buildplate rises after printing bottom layers is greatly reduced (though its still loud when the plate is full). If the next time I empty the vat this non-FEP film isnt all dinged up, Ill bump up the rating to the max. If youre printing small stuff with standard gray/white resins I say stick to the cheaper FEP sheets. This non-FEP stuff (whatever it is) is probably better for black resin, if you print items with large surface area, or other stuff thats notorious for its reluctance to adhere to the buildplate. === [UPDATE 4/10/20] I must be at least on the 30th print session by now, mostly full buildplates, and this film is in way better shape than ordinary FEP. When you print the same thing constantly, the film will get dings from supports eventually, but theyre a lot fainter with this film. [UPDATE 1/13/2021] Its incredible that the same sheet from almost a year ago has held up so well. The only sign of deterioration on the sheet is a hazy patch near the middle that gets heavy use. Ive simply moved models off that area and they still print just fine. I think its important that you get your Z Home right for maximum durability. This is so the build plate doesnt lower more than it has to and prevent dinging the sheet with the supports as they print.

Because then more people will buy it, and I want them all for myself. But they deserve the 5 stars, so it wouldnt be fair. Im never ever going back to regular fep.. NFEP by EPAX is the biggest game changer Ive ever discovered with resin printing. For a year I used the traditional FEPs that cost like $15 for a 5 pack, they did the job but would always leave a gooey residue on the film after each print and would wear out QUICK. These nfeps dont leave a TRACE of cured resin goo on the film, Ive waited 2 weeks to leave this review and have ran over 10 full plate prints on one and not a single issue and looks brand new still with plenty of life left. UPDATE: Theyre crap. ordered another set and these lasted maybe 5 prints before it became stretchy and leaky, ruined my LCD because I trusted this product. Looks like in going back to regular FEP...
