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: 200C 250C, bed temperature: 80C 100C, fan speed: 0%, printing speed: 40130mm/s.Specification:Item Type: Carbon Fiber PETG FilamentMaterial: PETG+Carbon FiberColor: BlackDiameter: 1.75 mm/0.07in +/- 0.02 mmRecommended Printing Temperature: 200C - 250CRecommended Bed Temperature: 80C - 100CPrinting Speed: 40-130mm/s.Package List:1 xCarbon Fiber PETG FilamentNote:Due to the addition of carbon fiber, this 1.75mm PETGCF 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.
