Switch the mode from Simple to Expert at the top right first. Several of these settings do not exist in Simple mode.
Start from the 0.20 mm Speed or Quality profile for your printer and change only what is below.
The list
| Setting | Where | Value |
|---|---|---|
| Layer height | Layers and perimeters | 0.2 mm |
| Perimeters | Layers and perimeters | 2 |
| Solid layers, top and bottom | Layers and perimeters | 3 and 3 |
| Fill density | Infill | 10 percent |
| External perimeters speed | Speed | 25 mm/s |
| Perimeter generator | Layers and perimeters | Arachne |
| Elephant foot compensation | Print Settings, Advanced, Slicing | 0.15 mm |
| Seam position | Layers and perimeters | Aligned or Rear |
| Lift Z | Printer Settings, Extruder 1 | 0.2 mm |
| Generate support material | Support material | Off |
Elephant foot compensation is positive
Like Bambu Studio and unlike Cura, PrusaSlicer's Elephant foot compensation takes a positive number for the amount to pull the first layer in by. Enter 0.15.
It lives under Print Settings, Advanced, Slicing, which is not where most people look for it.
Perimeter generator
Perimeter generator under Layers and perimeters should be Arachne rather than Classic. Arachne varies the extrusion width so that a 0.8 mm wall prints as two solid lines instead of two lines with a gap between them.
Slice and check the layer preview at about half blade height. Two lines touching, no gap.
PrusaSlicer specific notes
- Small perimeters speed under Speed applies to short closed loops. Detailed cutters have plenty of these. Set it to the same value as external perimeters so the whole blade prints at one speed and the extrusion stays consistent.
- Slice gap closing radius under Advanced, Slicing defaults to 0.049 mm. If a fine imprint detail vanishes from the slice, raising this slightly can recover it, but check the preview afterwards because it can also bridge two details that were meant to stay apart.
- Detect thin walls is the old mechanism and is not needed with Arachne. If you turn it on to rescue something, check the preview.
- Ensure vertical shell thickness should stay on. It is what keeps the blade solid where it meets the flange.
- Avoid crossing perimeters reduces the chance of the nozzle dragging across the top of a finished blade section during travel.
