Has anyone thought about printing narrower lines in order to get sharper corners? Once Linear advance or Pressure advance is activated, you don't get bulging corners anymore... but can we do better?

Has this been implemented anywhere yet? Does it have a name?

You can totally extrude both narrower and wider than your nozzle. Heck, if you have a Slic3r based slicer like PrusaSlicer, Orca, SuperSlicer, etc and your extrusion width is expressed as a percentage, that percentage is a percentage of layer height - NOT nozzle diameter.

If you're using 0.2mm layers, your extrusion with is expressed as a percentage, and you're using a 0.4mm nozzle your extrusion with is less than your actual nozel diameter. Unless you're have 200% or more as the value.

I print most of my prints with a 0.4mm nozzle and 0.6mm extrusion width.

This is definitely not true of OrcaSlicer, at least not anymore. I’m running an 0.6mm nozzle and 120% layer width at 0.2mm layer height results in 0.72mm line width, not 0.24mm.

It makes more sense for this parameter to be relative to the nozzle width if you ask me. But that doesn't change that you can extrude wider or narrower than the nozzle.
