Perimeters bulging out at a specific height

Bambu Lab A1 Series General Discussions
1

Hi everyone,
I’m experiencing an issue while printing a PLA model on a Bambu Lab A1 using Bambu Studio.
At a certain height (always the same), the outer perimeters start bulging out noticeably compared to the rest of the print. This happens exactly when the geometry narrows and the perimeters become smaller.

  • Slicer: Bambu Studio (latest version)
  • Printer: Bambu Lab A1
  • Material: PLA
  • Temperature: 220 °C
  • The issue occurs only with this model and always at the same height

Thanks in advance to anyone who can help!

If it’s just the model, it’s likely that it is causing the issue, especially if other things print fine. I assume you’ve tried another model with similar height to see?
