Features: 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 FDM 3D printers, for MK3, for Ender 3, for Monoprice, and more. 4.Application: Lightweight and durable, 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: Smooth, stable printing, the recommended printing temperature: 200C ? 240C, bed temperature: 100C ? 120C, 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: 200C - 240C Recommended Bed Temperature: 100C - 120C Printing Speed: 40-130mm/s PackageList:1 x CarbonFiberPETGFilament NoteDue 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 resistant 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. Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
