I can think of two problems:

First, not every Release Film is the same. You are talking specifically of FEP which is mostly used to describe the Release film and was commonly used for that but is the material that the Release film is made from. There are different types like the already mentioned FEP but also nFEP, PFA, ACF and probably others as well. Each of those materials has a different rigidity which would mean that they peel away from the Model sooner or later. According to this, FEP is much more flexible than PFA or ACF.

Second, the durability of the Release Film. Over time, the Release film will wear out and need to be replaced. They could become more flexible the more you use them. Cutting it too close could mean that your models will fail from one print to another.

Some other thoughts:

• How much the Release film flexes could also depend on the surface area being printed. More surface area could mean that the layer is sticking to the release film longer
• The same would apply to the Exposure rate because higher exposure rates make your layers stick more, including to your Release film
• Assembly also plays a role in this. Since you need to replace the Release film at some point, you could add more or less “slack” on the film which would throw off your previous test massively.

While I like the idea, I think it would signal a false sense of confidence in your printer because if you “dial in” your lift distance and the model then fails, people could start looking in the completely wrong direction to fix a problem. I mean, with that many variables to consider, people still download the validation matrix without adjusting their bottom and transition layers based on the description and then ask why their exposure test doesn’t work.

They already tried that with Anno 1800, didn’t work out that well.

They look so disappointed and concerned.

It’s a bit of an infuriating story that I had not so long ago.

I have a Playstation account and I recently wanted to log into that account on the PlayStation website. The Password I had saved in my Bitwarden Password Manager was apparently wrong. Okay, then I will just reset it, that’s fine.

I went through the Password reset process and generated a new Password, pasted it into the Password field and sent it and everything was fine. I tried to log in with that password and was told that the username or password was wrong. Okay, that is weird, since I reset the password just now the login name couldn’t be wrong because, well, I just used that for the reset.

I tried that several times with the same result and gave up.

A few months later, I wanted to try again and had the same problem. I wanted to sort that out so I went through the same process with the Support bot yet again which then told me that I should come back in the “office hours”. A company making 84 billion in revenue should be able to employ 24/7 customer service or at least tell me that when I request support and not let me go through the bot again.

So, I waited for the customer service personnel to be available and told them my problem. There I was told that “everything was looking fine on their end” and they quickly ended the support. I mean, yes, I was angry but wasn’t abusive to that person because if you couldn’t help me what should I do with my account, it also definitely wasn’t their specific fault. But I would, at least, have expected more than “Well, works on our end, sucks for you, bye”.

The next time I tried again and got a more competent Support dude and we ran through the same troubleshooting steps as before. Reset password (even though I just did that, again, through the bot), logged in again and failed again. This time they suggested that I could use a “normal” password that I don’t generate. THAT worked for some reason.

All of my generated passwords in Bitwarden are up to 32 long with all possible characters, depending on what the website allows or expects. If a website, for example, doesn’t allow 32 characters, I adjust and shorten it to the maximum length they allow. That worked without issues so far.

Well, turns out that the field that you use to reset your password has a character limit of 30 characters. But, this would be fine if the dialogue tells you that your password is too long, but it doesn’t. It just cuts off at 30 characters and happily saves that.

However, the Password field that you use to log in doesn’t have that restriction.

This means that you reset your password with a 32-character long generated password, which is saved in your vault, PlayStation saves a 30-long password and then you use the 32-long password to log in, which fails because it isn’t the same.

And this isn’t even mentioned in the password guidelines. It only said “min 8 characters” but not the maximum.
