Superior Mechanical Properties: Containing chopped carbon fiber,TINMORRY PLA-CF filament 1.75mm is stronger and stiffer than ordinary PLA, making it more suitable for printing general engineering parts or models requiring impact strength. Unique Texture & Matte Finish: Effectively hides the layer lines, our PLA-CF 3d printing filament gives the prints a smoother and higher quality appearance. With matte printing surface, it is the ideal filament for printing models with matte appearance. Dimensional Stability & Easy support removal: Compared to traditional PLA, PLA-CF filament shrinks less and does not warp, allowing for a perfect fit between printed models.TINMORRY carbon fiber 3d printer filament is designed to support itself.It is easier to remove than regular PLA filament,while maintaining a smooth support surface. Printing Settings: 1. For better printing quality, please dry it before printing and keep it sealed after use. 2. Please use wear-resistant steel nozzles(0.4 mm,
