PLA Aero Print Settings
Expert-recommended PLA Aero (PLA) settings for all Bambu Lab printers
Why use PLA Aero?
- Foaming PLA that expands during printing for lightweight parts
- Up to 50% weight reduction compared to standard PLA
- Unique matte, foam-like texture finish
- Excellent for large decorative pieces with reduced material usage
- Hides layer lines naturally due to foaming texture
- Great for cosplay props and display pieces
What are the best PLA Aero print settings?
Use default Bambu Lab temperature profiles for PLA Aero. Recommended outer wall speed is 120 mm/s. Default layer height: 0.24mm.
| Setting | Value | Note |
|---|---|---|
| quality.layerHeight | 0.24 | Thicker layers allow foam to expand properly |
| quality.lineWidth.default | 0.55 | Wider lines for foam expansion |
| speed.layers.outerWall | 120 | Moderate speed for even foam texture |
| speed.layers.sparseInfill | 300 | Moderate infill speed |
| strength.infill.density | 10 | Low infill — foaming already adds internal structure |
| support.filament.interface | Support for PLA (Bambu Lab) | Breakaway interface — foaming texture aids removal |
| support.filament.base | Same as model | PLA Aero as bulk support |
What nozzle size should I use for PLA Aero?
0.4mm — foaming effect is reduced at fine settings
0.6mm nozzle RECOMMENDED — allows better foam expansion
0.8mm for maximum foam effect and speed
How do I dry PLA Aero filament?
Dry PLA Aero at 50°C for 4-6 hours. Low priority — PLA absorbs moisture slowly
What support material should I use with PLA Aero?
Recommended: PLA Aero base + Support for PLA interface
Base: Same as model (PLA Aero) | Interface: Support for PLA (Bambu Lab)
PLA Aero as bulk support with breakaway interface. Foaming texture makes base support removal easier than standard PLA.
~25% less support filament used
Expert Tips for PLA Aero
- PLA Aero expands during printing — actual dimensions will be slightly larger than sliced.
- The foaming effect increases with higher temperatures — experiment with +5-10°C.
- Large nozzles (0.6-0.8mm) give the best foam texture and weight reduction.
- Not suitable for precise dimensional parts due to foam expansion variability.
