aeWorthy™ PLA-Aero

PLA-Aero is a type of lightweight 3D printing material specially developed for aircraft model, ship model, drone and other fields. PLA-Aero controls the foaming ratio of the material by adjusting the temperature during the printing process so that the density of the material extruded by the nozzle can be adjusted within a certain range. With this technique, it is easy to reduce the weight of the model. In the best-case scenario, the model weight can be reduced to 50% of a model printed with ordinary PLA. In addition to that, the matte texture of the printed surface can reduce the visibility of printed layers and thus give a smooth surface finish.

Other sugggestions:

Since PLA-Aero adopts the “On-Demand foaming” technology, the filament will continue to expand in the nozzle after being heated during the printing process. Therefore, it will cause unavoidable stringing during the nozzle movement. Even adjusting the retraction setting in the slicing software cannot solve this problem. Based on the above, it is recommended to turn off the retraction setting. The string on the surface of models can easily be removed by hand.
