eSUN PLA-LW: lightweight PLA with physical foaming tech, up to 220% expansion and 0.54 g/cm³ density. Ideal for RC planes and drones—reduces weight and improves flight. Premium matte finish hides layer lines, easy to paint.
eSUN PLA-LW Filament — Lightweight PLA for Extreme Weight Reduction
eSUN PLA-LW (Lightweight PLA) is an innovative 3D printing filament engineered specifically for extreme weight reduction and aeromodelling. Utilizing advanced physical microsphere foaming technology, its foaming ratio can reach up to 220% via temperature control, bringing the density down to an astonishing 0.54 g/cm³. In the realm of RC planes and drones, PLA-LW significantly reduces fuselage weight, lowers wing loading, and decreases stall speed, dramatically enhancing flight time and aerodynamic performance. Furthermore, the foamed material expands to create a premium, fine matte finish that virtually eliminates layer lines. It also offers outstanding paint adhesion, making post-processing and DIY customization an absolute breeze.
