ExtrudoWhy is my 3D print petg stuck too hard to the bed?
Petg stuck too hard to the bed is usually caused by petg bonds unusually strongly to glass and some pei surfaces at high bed temperatures. The finished PETG print is extremely difficult to remove and may damage the bed surface

What it looks like
The finished PETG print is extremely difficult to remove and may damage the bed surface
Most likely cause
PETG bonds unusually strongly to glass and some PEI surfaces at high bed temperatures
How do I fix petg stuck too hard to the bed? Step-by-step
- 1
Lower bed temperature slightly
Reduce bed temperature by 5-10°C within PETG's recommended range (usually 70-90°C).
Done when: Print releases with normal effort once bed has cooled
- 2
Let the bed cool before removing
Wait until the bed has cooled to room temperature before trying to remove the print — PETG releases much more easily once cool.
Done when: Print pops off with light pressure after cooling
- 3
Use a release agent
Apply a thin layer of glue stick or a PETG-specific release agent to the bed before printing.
Done when: Print releases cleanly without excessive force
