Bamboo ASA Aero
Bambu ASA Aero is a self-foaming material known for its exceptional durability and robustness. The heat-sensitive foaming allows for controlled model density, resulting in extremely lightweight printed models. In addition, the material has excellent resistance to temperature, water and UV rays. With these unique properties, it is ideal for printing long-lasting outdoor models and weight-sensitive projects such as RC airplanes.
Impact resistant and built to last
Compared to other foaming filaments, ASA Aero is more robust with higher layer strength, making it more resistant to shocks, collisions and drops, making it perfect for demanding, high-load applications.
| Property | Bamboo ASA Aero | Bamboo PLA Aero | Wood PLA |
|---|---|---|---|
| Toughness (impact strength – XY) | 32.0 kJ/m² | 24.5 kJ/m² | 7.9 kJ/m² |
| Layer adhesion (impact strength – Z, dry state) | 3.4 kJ/m² | 2.5 kJ/m² | 1.1 kJ/m² |
| Layer strength (bending strength – Z) | 24 MPa | 15 MPa | 15 MPa |
Ultra-low weight, controllable density
At only 50–75% the density of regular ASA prints, ASA Aero is featherweight and designed for weight-sensitive objects such as RC planes and UAVs (unmanned aerial vehicles). Thanks to its controllable foaming, ASA Aero can achieve lower density in prints by increasing the print temperature or decreasing the flow rate.
Factors affecting average print density
The average density of prints varies depending on changes in parameters such as actual printing temperature, flow rate ratio, print speed, model size, wall thickness, and infill density.

Printing tips
-
Foaming ASA materials (ASA Aero) have high demands on material drying and parameters. Please read the ASA Aero Printing Guide carefully before starting the printing process.
-
Drying conditions: 80 °C for 8 hours. ASA Aero is very sensitive to moisture. For optimal print quality, additional drying is recommended both before use and after storage. For more details see: Filament Drying Recommendations on WIKI.
-
To minimize warping, avoid printing large models with high infill density. Use closed printers and make sure the build plate is properly glued for better adhesion. Set lower print speed and higher heatbed temperature. For more details see: Common print quality problems and solutions on WIKI.
-
During printing, strong and unpleasant odors may be released. Make sure the printer is in a well-ventilated area and use sealed printers.
