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?

    in 3d space, your corner extrusion would suddenly be much thinner, so the choices for your filament would be to either droop to be supported by the previous layer or for the filament to sit underextruded in space if your part cooler is really up to the challenge.

        Because that’s what happens when you reduce the amount of material being extruded in order to create much thinner lines in order to create sharper corners.

          But the corners will have the same amount of material, since it is basically extruding 2 times on the same location during a corner.

          Which is why the original corners have too much material.

            At this point there is basically only one way of knowing :D. I’ll generate some g-code and give it a go.

          It’s all a question of what exactly “much thinner” means, I expect to have some positive effect of the proposed method even when the minimum extrusion width is above the threshold where things become too thin.

          Overall I expect the described method to make more sense with large nozzles and wide extrusions.

          Thanks for explaining what you mean!
