Overextruding or layer seams

[Ziogianni84 3]

Hi guys I have an issue, here it's

Is it an overextruding problem or layer seams? How can I get rid of it?

I'm using ultimaker pla and standard settings (UM3 fine quality)

The image shown a cleaner situation since I rubbed the inner side with my finger to remove the exceeding zits.

To me it looks like you are having issues with layer seams. You would have saw over-extrusion at the whole printed part not only at a few layers.

What you can do about that is to change your retraction settings.

The important settings to consider are retraction distance and retraction speed. If your retraction distance is not high enough, it will result in plastic oozing out of your nozzle when the printer finishes the outer perimeter. On the other hand, it’s important not to have this value too high as it can increase the chances of clogging your hot end (I believe)
