Temperature is the single most important variable in FFF printing. Get it right and almost everything else becomes tunable. Get it wrong and you fight warping, weak layers, stringing and clogs that no other setting can fix.

Wood-filled PLA | 190–220 °C | 50–60 °C | Not needed | 60–100% | Use 0.5 mm+ nozzle to reduce clogging |
Metal-filled PLA | 195–225 °C | 50–60 °C | Not needed | 50–80% | Hardened nozzle; wear-resistant extruder gears |
How to Use This Chart
These are starting points, verified across common 1.75 mm filaments, not universal constants. Three factors shift the right number:
1. Nozzle diameter. A 0.6 mm nozzle needs slightly higher temperature (+5 °C) because the melt has less residence time and more surface area to heat. A 0.2 mm nozzle often needs −5 °C to avoid oozing.
2. Print speed. Doubling speed roughly requires +5 to +10 °C, because the filament spends less time in the melt zone. Slow prints at 20 mm/s can run cooler; fast prints at 150 mm/s need more heat.
3. Chamber and ambient temperature. An enclosed printer at 45 °C ambient behaves very differently from an open frame at 15 °C in winter. If your workshop gets cold, raise bed temperature by 5–10 °C and slow the first layer.
Fine-Tuning: The ±5 °C Method
Never tune in steps larger than 5 °C, and change one variable at a time.
To find your nozzle temperature:
- Print a temperature tower covering the range in the chart (e.g. 240 → 190 °C for PLA, 265 → 230 °C for ABS).
- Inspect bridging, surface finish and layer bonding at each band.
Why the lowest? Because excess temperature causes stringing, oozing, sagging overhangs, and thermal degradation of the polymer. Cold filament fails loudly; hot filament fails subtly.
To find your bed temperature:
- Print a first-layer test patch at the low end of the range.
- If corners lift or edges shrink away, raise the bed by 5 °C.
- If the part is hard to remove or the bottom surface is glossy and distorted, lower by 5 °C.
- For PETG on glass, always use glue stick as a release layer regardless of temperature.
First Layer vs Remaining Layers
Setting | First Layer | Layers 2+ |
Nozzle temperature | +5 °C above normal | Normal |
Bed temperature | Same or +5 °C | May drop 5–10 °C for ABS/PETG |
Speed | 15–25 mm/s | Normal speed |
Cooling fan | Off (except PLA) | Per chart |
Printer-Specific Adjustments
Different machines read temperature differently by 5–15 °C depending on thermistor placement and hotend design. Practical implications:
- Direct-drive, all-metal hotends
Temperature and Common Defects
Defect | Likely Temperature Cause | Correction |
Stringing / oozing | Nozzle too hot | −5 °C, increase travel speed |
Weak layer adhesion | Nozzle too cold | +5 °C, reduce cooling fan |
Warping / corner lift | Bed too cold, ambient air moving | +5 °C bed, enclose the printer |
Blobs and zits | Nozzle too hot, wet filament | −5 °C, then dry the filament |
Rough, foamy surface | Wet filament | Dry it — temperature will not fix this |
Poor overhangs | Too hot, too much cooling | −5 °C, increase fan |
Layer shifting | Too fast / loose belts | Not temperature-related; check mechanics |
A Note on Verification
The best temperature in the world will not compensate for inconsistent filament. If your prints change character halfway through a spool, suspect diameter variation rather than your temperature settings —
here is why ±0.02 mm tolerance matters.
FAQ
What temperature should I print PLA at?190–220 °C nozzle, 50–60 °C bed, 100% cooling fan. Start at 205 °C / 60 °C and tune from there.
Why does PETG need a higher bed temperature than PLA?PETG has poorer first-layer adhesion to most surfaces, so a 70–85 °C bed is needed to hold it down. Always use a release agent on glass.
Can I print ABS at 230 °C?You can, but layer bonding will be weak and parts will split. ABS needs 240–260 °C plus a heated chamber for reliable results.
Do I need to change the temperature for coloured filament?Not usually. Pigments have a minor effect on melt flow; white and some metallic colours may print marginally better 5 °C hotter.
