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!

    I just use my textured sheet and remove very carefully - but I tend to use harder TPUs which makes flexing the sheet more effective.

    I have heard people say that TPU is the reason they still keep a glue stick handy and the Prusa material matrix says to use it on their smooth PEI sheet. And it suggests a polypropylene sheet is also applicable without glue stick.

      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?
