What each slicer setting does and when to change it. Applies to OrcaSlicer, Bambu Studio, PrusaSlicer, and Cura with minor naming differences.

Layer and Quality

Setting	Effect	When to change
Layer height	Print resolution and speed	0.1mm = fine, 0.2mm = standard, 0.3mm = fast
First layer height	Adhesion and squish	Usually 0.2–0.3mm regardless of layer height
Line width	Extrusion width	Typically 100–120% of nozzle diameter
Seam position	Where layer transitions appear	Rear = hidden, Random = scattered, Aligned = visible line

Setting	Typical range	Notes
Outer wall	30–60mm/s	Slower = better surface quality
Inner wall	100–200mm/s	Not visible — can be fast
Infill	150–300mm/s	Not visible — go fast
Top surface	30–50mm/s	Slower = smoother top
First layer	20–30mm/s	Always slow for adhesion
Travel	200–300mm/s	No filament — go fast

Setting	Notes
Density	10–15% for visual prints, 30–40% for functional, 100% for maximum strength
Gyroid	Best strength-to-material ratio for functional prints
Grid / Lines	Fastest, good for non-structural parts
Lightning	Minimum material for display models
Adaptive cubic	More infill near surfaces automatically

Setting	Notes
Wall count	2–3 for visual prints, 4–6 for functional — adds strength more than infill
Top/bottom layers	3–5 layers — more = better top surface with low infill
Top surface pattern	Monotonic or Archimedean = smoothest top

Setting	Notes
Support type	Normal (tree recommended for most prints)
Overhang threshold	30–45° typical — steeper angles need support
Interface layers	2–3 layers at 0.2mm gap — easier removal
Z distance	0.15–0.25mm — closer = stronger but harder to remove
Support material	PVA for dual-material, use same material for single

Material	Nozzle	Bed	Notes
PLA	190–220°C	60°C	Most forgiving
PETG	230–250°C	70–85°C	Hotter than PLA, stringing risk
ABS	230–250°C	90–110°C	Needs enclosure
ASA	240–260°C	90–110°C	Similar to ABS
TPU	220–240°C	30–60°C	Print slow, no retraction or minimal
PA (Nylon)	250–280°C	70–90°C	Dry filament critical
PC	260–300°C	100–120°C	Needs all-metal hotend

Setting	Notes
Distance	Direct drive: 0.5–1.5mm. Bowden: 4–7mm
Speed	25–60mm/s — too fast = grinding
Enable combing	Keeps travel inside the model — reduces stringing without retraction

Reduces corner bulge and start/stop artifacts. Tune with a tuning tower:
