Lightweight PLA: PolyLite Lightweight PLA filament has a low density of 0.9g/cm³, compared to 1.17g/cm³ for standard PLA. It uses the same printing settings as regular PLA, ensuring easy compatibility with most 3D printers. Unlike traditional lightweight PLA, it does not foam during printing, preventing common foaming issues. High Rigidity & Good Layer Adhesion: Polymaker Lightweight PLA filament provides high rigidity and excellent layer adhesion, making it ideal for creating stiff parts for radio-controlled planes. This reliable Low Weight PLA features great bed adhesion, consistent color, and dimensional accuracy, while eliminating issues like warping, jamming, blobs, and layer delamination. Note: Turn off the fan for the first layer to improve bed adhesion.
