Pro Tip: Keep a log of optimal temperatures for each filament spool you use. Even the same brand and color can vary between batches.
Temperature Calibration
Find the optimal printing temperature for your specific filament.
Why Calibrate Temperature?
Every filament, even of the same type, can have different optimal temperatures depending on the manufacturer, colorants, and additives. The right temperature affects:
- Layer adhesion and strength
- Surface quality and finish
- Stringing and oozing
- Bridging and overhang performance
- Print speed capabilities
Running the Test
- Open OrcaSlicer and go to Calibration > Temperature
- Select your filament type (PLA, PETG, ABS, etc.)
- The slicer will set appropriate temperature range:
- PLA: 190-230°C
- PETG: 220-260°C
- ABS: 230-270°C
- Click "OK" to generate the temperature tower
- Slice and print the model
Evaluating Results
Examine each temperature section of the tower for:
| Feature | Too Hot | Too Cold | Optimal |
|---|---|---|---|
| Stringing | Lots of strings | Minimal | None or very little |
| Bridging | Droopy, sagging | Clean but may snap | Clean, strong bridges |
| Overhangs | Curling, drooping | Clean but weak | Clean, solid |
| Layer adhesion | Good to excessive | Weak, delaminates | Strong bond |
| Surface | Glossy, possibly blobby | Matte, rough | Consistent finish |
Break Test
After printing, try breaking sections of the tower:
- Too cold: Breaks easily between layers (delamination)
- Too hot: Strong but may have other quality issues
- Optimal: Breaks through the material, not between layers
Applying Results
- Identify the section with the best overall quality
- Note the temperature for that section
- Update your filament profile with this temperature
- Consider using slightly higher temp for first layer (+5°C)
Temperature Guidelines
| Material | Typical Range | Start Point |
|---|---|---|
| PLA | 190-220°C | 210°C |
| PLA+ | 200-230°C | 215°C |
| PETG | 220-260°C | 240°C |
| ABS | 230-260°C | 245°C |
| ASA | 230-260°C | 245°C |
| TPU | 220-250°C | 230°C |
