Please provide your 3MF project file. Are you using arachne slicing engine?

thanks, I will try it

Provided 3MF is not PrusaSlicer project file. (File - Save project as).

Ok. You may also try pressure equalizer feature (it can gradually slow down the speed of the external perimeter to the same speed as external perimeter).

There are some errors in the model. It is sliced correctly after repairing the model. I am attaching repaired model. [fixed_messy_slice_layer_15.zip](https://github.com/prusa3d/PrusaSlicer/files/13271542/fixed_messy_slice_layer_15.zip)

I just repaired it using built-in windows repair service (it is based on Netfabb).
