These are the settings I use for printing the wargaming terrain we sell. These work on our Prusa Mk3S printers and may require tweaking when applied to other printers – take them as a starting point.
I find that 0.2mm layer height works as a good compromise between speed and quality, where if you want something of higher quality I find that the 0.08mm settings work well and we used those when printing the example pieces for our Stone Town Kickstarter.
Via PrusaSlicer these are our preferred settings at 0.2mm layer height with a 0.4mm nozzle:
Vertical Shells: 3
Horizontal Layers, Top: 8
Horizontal Layers, Bottom: 4
Seam Position: Nearest
Infill: 12%, Adaptive Cubic
Perimeters: 55mm/s
Small Perimeters: 20mm/s
External Perimeters: 55mm/s
Infill: 85mm/s
Solid Infill: 85mm/s
Top Solid Infill: 35mm/s
Bridges: 55mm/s
Gap Fill: 35mm/s
Travel: 120mm/s
At higher quality I change these – 0.08mm layer height:
Layer Height: 0.08mm
Vertical Shells: 3mm
Horizontal Layers: 12 top, 4 bottom
Perimeters: 40mm/s
Small Perimeters: 15mm/s
External Perimeters: 35mm/s
Infill: 85mm/s
Solid Infill: 85mm/s
Top Solid Infill: 35mm/s
Bridges: 65mm/s
Gap Fill: 35mm/s
Travel: 120mm/s
