Polymaker - Fiberon PA612-CF15 is a carbon fiber reinforced nylon (PA612) filament. It combines high strength with improved moisture resistance. Due to its chemical structure, it is less sensitive to moisture than PA6 and PA6/66 materials. In addition, it offers better mechanical properties than standard PA12 filaments. With 15% carbon fiber, this filament is even stiffer and stronger. The Warp-Free™ technology ensures precise prints without distortion. It is resistant to high temperatures and heavy loads. This makes it perfect for technical and industrial applications. The black color gives your prints a smooth, professional finish.
