Running a Temperature Tower in Orca Slicer
temperature towercalibrationorca slicerfilament
A temperature tower prints the same geometry at decreasing temperatures, letting you see visually which temp gives the best results for your specific filament.
Why Run One
- Every filament brand has a slightly different ideal temp
- Finding the sweet spot improves: layer adhesion, surface finish, stringing, bridging
- Run once per new filament type/brand
In Orca Slicer (Built-In)
- Calibration → Temperature Tower
- Set parameters:
| Parameter | Value |
|---|---|
| Start temp | Material max (e.g., 230°C for PLA) |
| End temp | Material min (e.g., 190°C for PLA) |
| Step | 5°C |
- Slice and print
- Each section of the tower prints at a lower temperature
What to Look For
Evaluate each section on:
| Criteria | What to Look For |
|---|---|
| Bridging | Cleanest, least sag |
| Overhangs | Smoothest underside |
| Stringing | Fewest hairs |
| Layer adhesion | No visible gaps |
| Surface quality | Smoothest top/sides |
Pick the temperature where most criteria score best. Often a compromise — stringing gets worse as temp increases, but adhesion gets better.
Typical Results by Material
| Material | Typical Sweet Spot |
|---|---|
| PLA | 210–220°C |
| PLA+ | 220–225°C |
| PETG | 235–242°C |
| ABS | 242–248°C |
Saving the Result
Update the filament profile's nozzle temperature with your finding. Add a note with the brand, color, and date tested.
