3D Printer Carbon Fiber Filament: PolyLite PLA-CF is a carbon-fiber reinforced PLA filament that offers high strength and rigidity while maintaining good toughness. It also features an impressive satin and matte finish, resulting in smooth-looking prints. Tangle-Free & Moisture-Proof: Meticulously wound to prevent tangling, the filament is dried and vacuum-sealed in a resealable zip lock bag with desiccant. Important: Always hold onto the tip of the filament to avoid knots. Use the holes on the spool to prevent this issue. Excellent Layer Adhesion & Rigidity: No warping, jamming, blobs, or layer delamination. PolyLite PLA-CF is a reliable carbon fiber 3D filament that offers great bed adhesion, consistent color, and dimensional accuracy. Printing Settings - Nozzle: 220°C; Bed: 50°C; Speed: 50mm/s. Note: Turn off the fan for the first layer to enhance bed adhesion. Cardboard Spool: Features upgraded 3.0 packaging with a fully recycled cardboard spool and box. Im
