What makes a perimeter "external"?
As a beginner I could not find the answer, even after searching for an hour. Maybe I'm missing a crucial piece of information or concept 🙂
What makes a perimeter "external" or "internal" + what is the difference?
In the following model, all parts facing "up" are marked as "internal infill". Isn't the quality of "internal infill" lower than "external perimeter"?
Can these areas be marked as "external perimeter"?
Any thoughts?

Welcome!
An external perimeter is one that forms an external vertical face of the object being printed. An internal perimeter is any additional perimeter that sits behind that. You are able to specify how many perimeters you want in PrusaSlicer. In your picture, the 'external' perimter is orange and 'internal' perimeter is yellow. If you change the number of perimeters in the print settings, you will see how this works.
The red infill in the picture is actually not 'internal' infill, it is 'top solid' infill. It forms an externally facing surface and is usually printed at a slower speed than other types of infill in order to maximise quality.
Hope that helps!

Ah! The color of "internal infill" and "top solid infill" look a bit similar on a big screen 🙂 Now it makes sense!
Thank you
