I just did my very first TPU print after years of printing PLA and PETG, and I've gotta say: That stuff sticks like a mofo on the textured PEI plate..!!
The print turned out great and the default profile in BS needed very little tweaking.
I'm currently using Fiberology MattFlex 40D.

What do you guys use to ease the removal?
I've seen normal glue sticks, IPA and liquid glue made for 3D printing, but I figured it would be cool to ask the fine people here.

If you do use glue: Do you stick with a smooth PEI or maybe something else?

All feedback is appreciated!

Thanks in advance!

This is the first time I've had this much issue removing a print.
I knew it would stick fairly well on the textured PEI, but this was a whole new level. A bit surprised I didn't peel it, to be honest.

I'm leaning the same direction as those people: Buying a stick and keeping it around for those few times I do use TPU. PETG and PLA is still 98% of what I print, and they both come off easily on textured and PLA easily on smooth.

The question I'm stuck with though: Textured with glue or smooth with glue for TPU?

I used to throw the textured pei plate with the sticking print into the freezer for 15 min, made removal much easier. Now I just add baby powder onto my build plate, and remove the print at room temp. Much easier, a little messier

I've read that PEI makes TPU much more difficult, and switched out my PEI plate to my plain glass plate because of the horror stories. I just rattled off some TPU last night using glass and a single pass of a PVA glue stick, and it was super easy to get on and off the plate. Like if PETG was a bit stickier.

I suspect that cleaning the glue off the textured sheets is a bigger pain in the butt than off the smooth. But I say that as someone who never tried to clean PVA off of PEI.

Wait what?

The freezer trick I've heard of, but baby powder?
Applied before printing then, I guess?

My printer is enclosed and I'd wory about the aux fan blowing it everywhere.
Even with 0% fan for first layer, I'd never be able to perfectly distribute it under only the print...

Turn off the heat on the hotbed. TPU doesn't need it, and it makes removal much easier if you don't heat the hotbed.

Also reduces the amount the printer heats your room by 90% or so.

I've got a textured PEI bed and when I've printed TPU, the adhesion has been perfect, i.e. good enough that the part wasn't going to go anywhere unless I wanted it to, but still easy enough to remove when the print was done and the bed had cooled. I guess it could vary from filament brand to brand, so it's possibly worth trying the same brand as I used, which was cheap Geeetech stuff. It's £8 a roll, and I've used their cheap PLA for ages. I wouldn't recommend their ABS+, though, as it seems to break down at the lowest temperature that gives reasonable layer adhesion.

I've never had too much trouble removing TPU from a textured PEI plate. If the part doesn't want to come off, lift up a corner of the part with a knife and put a drop of IPA under it.

I use a bit of glue and try to remove it when it's still warm but not hot.
Zero issues so far.

Never tried it myself, but "functional print Friday" channel on YouTube uses IPA after printing with slow steady prying to remove stuck tpu. The IPA wicks under the print and releases it.

In my experience, TPU benefits from a higher first layer - it prefers being just "deposited" by the nozzle instead of slightly squished like for PLA and PETG. You can try raising your Z adjustment by 0.02 - 0.05mm and see if that makes it easier to remove.

If you work with transparent TPU and don't want it to turn white, print slow and cold.
