Black filament turns white on surface layer when pulled up

Hi Guys

I have been creating these thin black name plates with some mixed success.
They are about .60 mm in height. I can get a very smooth bottom first layer with either the lightly textured engineering plate or a smooth PEI plate.

Summary:
Overall I am just looking for a lightly textured build plate in which I can print a very thin material in black, that can be EASILY removed without damaging the print AND/OR without any post processing.

To date I have had mixed results when removing them from the build plate. I found Bambu Black Matte to be the best material so far, but I am open to other materials that may work better and come off more easily, if you know.

(PETG does not work well, it stick too well.)

Please note that I have adjusted filament and bed temps, model and filament settings and have used engineering and PEI plates, cool plates etc and even glues. I have even put the plate in the freezer.

Overall, when I remove them - there is always some areas that just don’t come up cleanly and they leave white marks or lines in various places where the material has “popped” off or “peeled” from.

I can only attribute it to being stress type marks on the plastic. If you reheat the areas with a heat gun the mark vanishes - but since the print is so thin - the heat usually warps the print and makes it unusable. (I use the heat gun trick, if needed, on much larger thicker prints with 100% success.)

I tried those new PEO plates (the ones with the mosaic, carbon fiber, herring bone patterns) - AND the model removes very easily. Just a slight lift and peels easily and leaves no marks. …BUT they have that pattern etching that transfers to the first layer and I don’t want that.

If there is another material that you know of that might help, please let me know.

BTW I ordered those new Cryogrip plates and waiting for them to be delivered. and will update.

Thanks

So in the meantime, this is a good solution that worked well for me

After you remove it, can you put the stressed face back onto the plate and just warm the plate up to 70 C or something?
That could be enough to resolve the marks without re-adhering to the bed.

I haven’t tried this before because it just occurred to me. If you try it and it works, please let me know!

That is exactly what I tried earlier today with the engineering plate and it did re-adhere to the plate. But that was a good idea. The hot water trick did work well though. Thanks for your reply.
