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?

    Why would that be? There is no physical rule saying that narrow extrusions need to be flatter as well.

      Because the same squeezing effect shown in the 2d plane would occur on the 3d plane as well.

        Hmm, not exactly sure I get your argument. I imagine every extrusion to tip slightly to the outside of the curve since material is elongated on the outside and squeezed on the inside. The excess material would be pushed to the inside while the outside of the curve would sink. Is that what you mean?

          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.
