Feature: 1. Excellent Mechanical Performance: Made of 80% PETG and 20% carbon fiber, resulting in a lightweight, high strength, and tough material that is resistant to brittleness and deformation. 2. Improved Printability And Matte Finish: The filament's mixture with 20% carbon fiber ensures easy feeding and printing, producing a smooth final print. 3. Wide Compatibility: This filament is designed to work perfectly with a range of for MK3, for Ender 3, and more. 4. Application: Lightweight and long lasting, it is suitable for applications requiring torsional, tensile and impact strength, and is widely used in the robotics, drone, automotive and aerospace industries. 5. Printing Recommendations: Stable printing, the recommended printing temperature: 200°C ‑ 250°C, bed temperature: 80°C ‑ 100°C, fan speed: 0%, printing speed: 40‑130mm/s. Specification: Item Type: Carbon Fiber PETG Filament Material: PETG+Carbon Fiber Color: Black Diameter: 1.75 mm/0.07in +/- 0.02 mm Recommended Printing Temperature: 200°C - 250°C Recommended Bed Temperature: 80°C - 100°C Printing Speed: 40-130mm/s. Package List: 1 x Carbon Fiber PETG Filament Note: Due to the addition of carbon fiber, this 1.75mm PETG‑CF filament may quickly wear out and clog a 0.4mm brass nozzle. It is strongly recommended to use a larger diameter (0.6mm or larger) wear proof steel nozzle and keep the nozzle clean between a few prints. For better surface finish and layer adhesion, it is also advised to dry the filament before printing.
