Is business that tight you can't replace this trash you sent me?
We were told by them that they will no longer reply to our emails.
I suppose they think we want to scam them for $20.
We will be filing a chargeback shortly instead. Would avoid unless you want a possible headache due to the owners arrogance.

I just wanted to ask did somebody else participated in this challenge?
I have a couple ideas that I would like to try and I need some FEP
Cheers!

Any suggestions on surface coatings that would offer resistance against resin corrosion?

Another point: you'll need more resin to fill the vat, but the unused portions of the vat that fall outside the imaging area serve as reservoirs. A good thing until you get really low. I've not bothered, but simple displacers could be dropped into place to push the resin to the middle.
Maybe some day I'll make this round vat out of heat-formed or cast clear acrylic?

FEP will deform a lot under just a bit of temperature increase if not tensioned properly. Just the weight of the resin on untensioned FEP will make it bow. I was pulling my hair out once when my previously perfectly working machine would not adhere to the build plate no matter what I changed. The only thing I did differently was change the FEP. I saw that it was sagging a bit so I added a bit more tension and it printed fine ever after. I now always listen for a good, tight tone when changing out FEP and retensioning. I do not use a substrate under my FEP (.005") but I see it might be a good thing for larger parts. I will never (did I just say that?) go back to any other method.

1. It helps form a seal. Most of the resin never makes it to the outer gasket because the FEP is stretched tight by a rounded tension ring. This is reassuring when 20 bucks in resin hovers over a $500 projector.
2. Wrinkles, in my experience, aren't pressed out by the weight of the resin. When I flipped my FEP to use the other side, I didn't get a perfect re-stretch. Subsequent prints had a wave. Not good.
3. I suspect having a loose FEP sheet would make cleaning more difficult because it wouldn't resist wiping pressure as strongly. Who knows...could be a non-issue.
Having established those points, if you support your FEP film with an undercarriage of glass or *acrylic, I suspect the FEP doesn't need to be crazy-tight like I have mine.
*good acrylic source: Walmart photo/document frames.
