Bambu Lab's PLA Aero is a lightweight, foaming PLA filament designed for high-performance 3D printing applications. With a diameter of 1.75mm and a weight of 1kg, this white filament is ideal for creating durable, impact-resistant models such as UAVs, aerodynamic prototypes, and gliders. The material achieves low density and weight by foaming at high temperatures during printing, resulting in small cavities within the prints. It comes with a reusable spool, promoting sustainable printing practices. For optimal results, it is recommended to dry the filament before use.
