What is your nozzle width, shell width, line width, inner line width, outer line width, layer height and print speed?
My nozzle width is 0.4mm, the shell width is also 0.4, line width is 0.4, I tried 0.35 but it just got way worse. The wall has to be only 1 layer thick because of the weight. Layer height is 0.15, but i tried everything from 0.1 to 0.2. Print speed did not make any difference, I also tried every possible speed.
The stl-file is a closed model, which is printed without top/bottom layers. The thickness is not a part of the model.

What is your nozzle width, shell width, line width, inner line width, outer line width, layer height and print speed? Please answer all of these as any one of these values being off can create what I see in the photo above.
By the way this is called "underextrusion".
It looks like you are doing very thin one pass shell width. I recommend 2 passes. So if your nozzle is .4mm make the line width .35 to .4mm and the shell width exactly double this (.7mm to .8mm).
Hmm. Another thought - is the thickness of the wall part of the model? I was assuming this was a "solid model" but now I think maybe the thickness of the shell is controlled in the model itself. Please check the thickness in a few places along that leading edge curve - if that is not exactly equal to twice your line width it would do just what we see in the photo.
If you don't have the ability to examine stl files accurately you could upload it somewhere and post a link to the stl file for this print (please don't post a link to a location that has a dozen stl files - we need to know which file - the more work you make it for us, the less motivated we will be to help).
