eSun ePC - Natural - 1.75mm Natural - 0.5kg

eSUN Natural Polycarbonate (ePC) Filament

eSUN’s Natural Polycarbonate filament is a transparent, high‑performance material designed for strong, lightweight, and impact‑resistant prints. Its see‑through properties open creative possibilities for covers, cases, screens, and even lenses, while its mechanical strength outperforms acrylics and rivals engineering plastics. Specially formulated with fire‑resistant additives (UL94 V‑2 rating), ePC is ideal for demanding applications such as electronics housings, soldering accessories, and functional prototypes requiring both durability and safety.
