High temp plate bubbling immediately

Bambu Lab X1 Series
1

I use the high temp plate with the included glue stick for ABS printing. My first plate developed some bubbles in the center and in other areas and I assumed it was because I tried to remove the print before the plate was fully cool. I worked around this as best I could, but yesterday I had to finally replace the hot sheet. I pulled the sticker off, cleaned the sheet, applied the new sticker using the handy dandy sticker applier, gently massaged the newly applied sticker to ensure uniform adhesion.
Then I made 2 ABS prints and it’s immediately bubbling in areas where there were no printed parts.
Has anyone else had this issue?

I have a similar experience with all of my plates that have a sticker.

From my experience the sticker of the hot plate (PEI) will settle after some time.
However, in addition I’m doing the following to get my plate flat again:

  • place the plate upside down so that the PEI sheet is touching the magnet surface (make sure nothing sticks to the PEI/clean the sheet)
  • optionally heat the bed to ~100C for about 10 minutes (I randomly selected this interval)
  • wait (for example over night)

So far the PEI has been flat again after this treatment.

same here… I have found that appyling the sticker, then leaving it for a day or two for the glue to set seems to help

Thanks for sharing this. The recommendation wouldn’t be to wait overnight as it’s a long period and would not help too much.

Here is what is our recommendations for solving the problem:

  1. Place the Cool Plate face down on the heated bed, with the Engineering side on top.
  2. Set the bed temperature to 100C and wait for 5-10 minutes
  3. Set the temperature to 30C and wait until the bed cools down to that temperature
  4. Remove the plate and inspect it, to see if the bubbles are removed.

This should help solve the bubbles on the plate.

I had the same bubble issue. I cleaned the glue stick off the build plate. I then flipped the plate, set bed to 100c and ran for 30 mins. It seems to resolve the issue. Well see if it holds up. Is this due to pulling prints off the bed before it cools?
