eSun ePLA-LW (Lightweight PLA) for model airplanes - printability and strength tests

ePLA-LW is filament designed by eSun for drone parts or model airplanes since it's density may be less than half of the regular PLA. Density of the filament can be controlled by printing temperature. Above 220°C it starts foaming (expanding), so we can reduce extrusion rate, but the final volume will be the same. In this video I tested the printability and strength of this filament and compared to eSun PLA+.
