Bambu Lab PLA Aero

Bambu PLA Aero achieves low density and light weight by foaming at high temperatures during printing and creating small holes inside the prints. It's the perfect choice for light-weight and energy-saving prints, including unmanned aerial vehicles (UAVs), aerodynamic models, and gliders. Foaming PLA materials (PLA Aero) have high requirements for material drying and parameter settings. Please carefully read Instructions for printing aircraft model with foaming PLA (PLA Aero) before starting the printing process.

Low Density and Light Weight

Bambu PLA Aero has almost the same filament density as regular PLA, while the prints density is only 50% to 80%.

* When printing models of the same volume, PLA Aero is about half the weight of PLA Basic.



Controllable Model Density

Achieve lower density of the prints by increasing printing temperature and lowering flow rate.

* The average density of prints will vary with changes in parameters such as actual printing temperature, flow rate ratio, printing speed, model size, wall thickness and infill density.

Parameter Setting When Increased Average Density Effect
Printing Temperature Increases ↗ Decreases ↘
Printing Speed Increases ↗ Stable or Increases ↗
Flow Rate Ratio Increases ↗ Increases ↗
Model Size Increases ↗ Decreases ↘
Wall Thickness (Wall Loops) Increases ↗ Increases ↗
Infill Density Increases ↗ Increases ↗

The relationship between the maximum foaming rate, minimum print density, and printing temperature of PLA Aero.

Specimen Test: Nozzle Type: 0.4 mm; Printing Speed: 80 mm/s; Model size (L*W*H): 80*10*4 mm³ (the XY direction) The actual required flow rate ratio and final model density may vary with different models.

Tough with Good Impact Resistance

Compared to pre-foaming Wood PLA, Bambu PLA Aero and its prints are tougher and more resistant to impact, collision, and falling.

Matte Finish For Easy Coloring

Bambu PLA Aero provides an easy-to-color matte surface texture with better dyeing results as compared to PLA Basic.
