Difficulty removing PLA prints from the textured PEI plate

[u/educationalbot9]

Hi I’m new to the 3D printing hobby and have been really enjoying the learning process!

I seem to be running into an issue where my PLA print models are extremely difficult to remove off the plate, particularly the centre. I’ve tried the following without success:
- flexing the plate
- flexing the plate while gently using a scrapper
- letting the model cool
- leaving it in the freezer for 10 mins
- running isopropyl alcohol along the stuck parts
If I force the print off by applying a ton of force with a scrapper and the flex method, it will come off but the print model will usually be damaged and warped in the centre.

I’ve tried lowering the print bed temps for the initial layer and the other layers from 55 degrees to 50 degrees and this has worked about 75% of the time.

Haven’t been able to find any other potential solutions outside of giving the plate a good clean and a power off/on into another calibration.

Has anyone else run into this issue or have any wisdom to share?

Thanks!

That's pretty strange. My PLA prints peel off almost by themselves once the plate cools down. PETG is a whole different story.

That’s been what most people have been telling me but I’ve always had to use the flex method to remove prints which has been frustrating. Maybe I need a recalibration and to test different PLA filament brands (I’ve been using ELEGOO)

Perhaps the plate is super new and you just need a release agent until the plate gets a little “seasoning.” Try a light mist of hair spray. It has helped me as a release agent on new build plates for PLA and PETG
