Controlling extrusion width

Is there a setting I can use to program the bead width, independently of the nozzle diameter?

So for example, output a 0.25 extrusion perimeter on a .40 nozzle?

On Simplify3d we have the "Extrusion Width" and "Extrusion Multiplier" parameters. Are there similar parameters in PS?

Thank you.

Thank you! I see it.

Is there a flow multiplier parameter?

It’s under filament settings.

Consider a smaller nozzle

You can go up to 200% of the nozzle size for width, assuming you're using quality nozzles. 120% is recommended. Going smaller than the nozzle size is tricky and tends to produce weak prints as you don't get the good "squish" with underlying layers. If you want extrusions that narrow, you're better off with a smaller nozzle.

I had a lot of success printing single perimeter walls with the extrusion width set to 0.25 on a .40 nozzle on Simplify3D. Want to try the same setup with PS.

I'll also swap to a .25 nozzle and compare.

Thank you,

Detect thin walls (or not)

If you encounter problems with the slicer not showing thin walls, try toggling Print Settings->Layers and perimeters->Quality->Detect thin walls. This setting lets PrusaSlicer try to print thinner walls but sometimes has the opposite effect. Ideally, you want to maintain the oval/stadium cross-section on extrusions so the extruded lines are wider than tall for good adhesion. If you go narrow, also consider using lower layer heights. I encountered this when trying to print thin text on top surfaces. It looked good but tended to bump off easily.

Very nice. Thank you for the tips.

I wonder how PS will deal with zero thickness surface walls.  Eager to see.

Appreciated it.
