Intro
Slicing turns your design into precise instructions (G-code) for the printer. Mastering the main settings unlocks better quality, strength, and reliability.
What slicing does
- Cuts the model into layers
- Calculates toolpaths for extrusion
- Adds supports/rafts/skirts as needed
- Controls temperatures, speeds, cooling
Choosing a slicer
- Cura — beginner-friendly, widely supported
- PrusaSlicer — detailed control, strong profiles
- Bambu Studio / OrcaSlicer — fast, modern UIs
Essential settings
- Layer height: 0.2 mm general; 0.1 for detail; 0.3 for speed
- Walls: 2–3 for most parts; 4+ for strength
- Infill: 15–25% grid/gyroid general use
- Temps: set by filament type
- Speed: start ~50 mm/s
- Cooling: 100% for PLA; lower for PETG
Supports & adhesion
- Overhangs > 45° need supports
- Use brims for small/tall parts
- Rafts as last resort
Preview & verify
Always preview toolpaths. Check first-layer, support contact points, and estimated time/material before you print.
FAQ
Do defaults work? Usually yes—then tweak deliberately.
Resin printers? Use Lychee Slicer or Chitubox; concepts differ from FDM.
Wrap-up
Slicing is where quality is made or lost. Start with sane profiles, learn a few key levers, and preview every time.
