●Featuring a semi-translucent crystalline base infused with fine, shimmering mica particles, the filament creates a natural, flowing gradient effect that gleams like streaks of lightning in the light. The PETG base material offers high toughness and resistance to brittleness, low shrinkage to prevent edge curling, and smooth extrusion with minimal stringing. Finished prints are crystal-clear and brilliant, delivering a stunning backlit effect—ideal for lampshades, dragon models, ornaments, and translucent reliefs—while allowing for gradient prints using just a single nozzle. Specifications: 1.75mm±0.02mm; vacuum-sealed, moisture-proof packaging.
