Bambu Labs PLA Aero is a specialized 3D printing filament integrating PLA with lightweight microspheres for weight-critical applications. Offering a unique balance of lightness and strength, PLA Aero is ideal for drone components, aerospace models, and more.

Physical Properties

  • Density: Typically lower than standard PLA, often in the range of 1.1–1.2 g/cm³
  • Heat Deflection Temperature (ISO 75 0.45MPa): 54°C
  • Tensile Strength: Comparable to standard PLA, ranging from 50-70 MPa depending on print settings and orientation

Aesthetic Quality

Bambu Labs PLA Aero usually has a matte, slightly textured finish due to the inclusion of lightweight microspheres. It comes in a limited range of colors, focusing primarily on functional rather than aesthetic applications.

Durability and Usage

While PLA Aero retains many of the mechanical properties of standard PLA, its unique lightweight characteristic sets it apart. It is especially useful for applications like drone components, aerospace models, and other scenarios where weight is a crucial parameter. Although not as strong as some other reinforced PLAs, it offers a unique balance of lightness and strength.


PLA Aero can be post-processed using similar methods to standard PLA, including sanding, drilling, and painting. Its slightly textured surface may require additional preparation for certain finishes, but it generally adheres well to common adhesives and paints.

Environmental Impact

Much like standard PLA, PLA Aero is derived from renewable resources like cornstarch or sugarcane and is biodegradable under industrial composting conditions. However, the presence of microspheres may affect its biodegradability to some extent. Despite this, it remains a more eco-friendly option compared to many other 3D printing materials derived from petrochemicals.

In summary, Bambu Labs PLA Aero filament offers a unique blend of lightweight characteristics combined with the ease of printing and environmental benefits of PLA. It is especially suited for applications where weight reduction is essential without significantly compromising strength. While not as robust as some of the reinforced PLAs or engineering-grade materials, its specialized attributes make it a compelling choice for particular use-cases.
