High Toughness & High StrengthImproved based on ordinary PLA, eSUN PLA CF carbon fiber PLA filament adds organic infiltrated chopped carbon fiber imported from Germany, which makes it present a better carbon fiber performance. High flexural modulus. Less wear on nozzles compared to PA CF. Low Shrinkage & Low Water AbsorptionCompared to PA CF, eSUN PLA CF has lower shrinkage and lower water absorption. Also, because it is based on PLA, it has the characteristic of PLA and doesn't need to print in enclosed chamber.No bubbles, less stringing, high successful printing rate.Stable dimensional tolerence.Good winding, does not overlap or tangle. Shine-free Matte Printed SurfaceWith chopped carbon fiber added, eSUN PLA CF presents an excellent shine-free matte printed surface and distinctive carbon fiber frosted texture. Also, the printed model doesn't have obvious layer lines compared to normal PLA. High Speed Printing & Fast CoolingeSUN PLA CF can maintain the p
