Your nozzle decides detail, speed and reliability. Here's the 2026 nozzle cheat sheet.
Sizes: what each one is for
| Nozzle | Best for | Trade-off |
|---|---|---|
| 0.2 mm | Miniatures, tiny text | Slow, clog-prone |
| 0.4 mm | Default — most prints | Balanced |
| 0.6 mm | Functional parts, abrasive materials | Less detail |
| 0.8–1.0 mm | Big vases, production speed | Coarse detail |
Materials
- Brass: best heat transfer, cheap — wears fast with abrasive filaments
- Hardened steel: required for PA-CF, glow, wood — slightly worse heat transfer (raise temp 5–10 °C)
- Ruby/obsidian: longest life for constant abrasive printing
Wear signs & replacement
Rough first layers, widening extrusion, stringing that wasn't there before, or visible orifice damage = replace. Standard rule: after every 3–5 kg of abrasive filament (PA-CF, glow, wood), inspect the nozzle.
