3D Filament Profiles:
How to Build, Save, and Reuse
Stop Recalibrating Every Spool. OrcaSlicer's filament profile system ensures your nozzle temperature, flow ratio, and pressure advance travel with every print job.
Stop Recalibrating Every Spool
Every time you swap to a new brand or color, you lose your settings if they aren't saved somewhere. OrcaSlicer's filament profile system is designed to prevent that.
Four parameters — nozzle temperature, bed temperature, Flow Ratio, and Pressure Advance — live inside each filament preset and travel with every print job that uses it.
This guide walks through how to fill in those parameters from scratch, where to save the results, and how to reuse the same profile when you switch filament brands without starting over.

The Four Parameters That Define a Filament Profile
These values override machine defaults to ensure your material is extruded with engineering precision.
Nozzle and Bed Temperature
Set in Filament Settings → Temperatures. Stores first-layer and default temperatures to ensure perfect adhesion and flow from the start.
FoundationalFlow Ratio
The extrusion multiplier for your filament. Calibrate using OrcaSlicer’s built-in single-wall cube test for dimensional accuracy.
Dimensional PrecisionPressure Advance
Reduces corner bulge and ringing. Once calibrated, save it directly to the profile to apply across all your printers.
Surface FinishMax Volumetric Speed
Caps the maximum extrusion rate to prevent underextrusion at high speeds. Essential for matching hotend melting limits.
Speed OptimizationHow to Create a Filament Profile in OrcaSlicer
Open Filament Settings
Go to Filament → Edit preset. Choose a close vendor profile and use 'Save as' to create your custom copy.
Set Temperature
Enter nozzle and bed ranges based on the manufacturer datasheet. Start in the middle of the suggested range.
Run Flow Ratio Calibration
Use Calibration → Flow Rate. Measure the wall with calipers and apply the formula to find your New Flow.
Run Pressure Advance
Go to Calibration → Pressure Advance. Identify the value where corner bulge disappears and enter it.
Max Volumetric Speed
Find your hotend's ceiling via Calibration → Max Volumetric Speed and set a conservative 80-90% limit.
Save as Named Preset
Click Save and use the format: Brand + Material + Variant (e.g., Polymaker PETG Black).
Filament Profile Configuration Template
Use this template to record your calibration results before saving them into OrcaSlicer.
| Parameter | OrcaSlicer Location | Measured Value | Reference Range | Notes |
|---|---|---|---|---|
| Nozzle temp (default) | Filament Settings → Filament | — | Per datasheet | Run temp tower if unsure |
| Nozzle temp (1st layer) | Filament Settings → Filament | — | Default +5 °C | Improves bed adhesion |
| Bed temperature | Filament Settings → Filament | — | Per datasheet | Match plate surface type |
| Flow ratio | Filament Settings → Filament | — | 1.00 base | Measure single-wall cube |
| Pressure Advance | Filament Settings → Filament | — | 0.01–0.08 (DD) | Use PA calibration |
| Max Volumetric Speed | Filament Settings → Filament | — | 12–24 mm³/s (PLA) | 80–90% of measured ceiling |
*Values in the Reference Range column are general guidance only. Actual results depend on your hotend and nozzle diameter.
Workflow Summary
Same brand, same material, new spool
Load profile → re-run Flow Ratio → update and save.
Different brand, same material
Duplicate closest profile → rename → re-run Temp, Flow, and Pressure Advance → save.
Different material type
Start from vendor preset → run all four calibrations → save under new name.
Where do results save?
Filament profile
Stores Flow Ratio, PA, Max Volumetric Speed, and Temps. This is the correct place for per-spool settings.
Printer profile
Stores machine-specific hardware limits like motor speeds and bed size.
Process profile
Stores layer height, speed, and infill settings for specific print qualities.
Frequently Asked Questions
Where do I find OrcaSlicer's built-in calibration tools?
In the top menu, go to Calibration. You'll find Flow Rate Calibration, Pressure Advance (line, pattern, and tower variants), Max Volumetric Speed, Temperature Tower, and several others. Each tool prints a test pattern and prompts you to enter the result.
Can I share filament profiles with other users?
Yes. Filament profiles are stored as JSON files inside OrcaSlicer's user data folder. You can export them as part of a .3mf project file or find the raw profile files and share them directly.
Do Pressure Advance values work with Klipper?
Yes, OrcaSlicer's Pressure Advance calibration generates a value for use inside OrcaSlicer's filament profile. OrcaSlicer passes this value via G-code to Klipper's system, confirming your macro configurations are correct.
My Flow Ratio is above 1.0. Is that normal?
Yes, values between 0.90 and 1.05 are common. A result above 1.0 means your printer is slightly underextruding. If it's significantly higher, check for partial clogs or worn nozzles.
What is Max Volumetric Speed?
It is the maximum rate (mm³/s) your hotend can melt and extrude filament. Setting an accurate ceiling lets OrcaSlicer cap speeds automatically, preventing gaps or weak layers.
Can I use these profiles in Bambu Studio?
No. OrcaSlicer filament profiles are stored in OrcaSlicer's own format and are not directly compatible. You must manually transfer the values between slicers.
