Creality Hyper ABS Filament for K1/K1 Max/K1C, Official 3D Printer Filament ABS 1.75mm for High-Speed Printing Convenient Open Printing ABS Filament, 1kg(2.2lbs) Spool Fit Most 3D Printer(Black) Black Hyper ABS

【Five Times Faster, More Efficient】By increasing the fluidity of common ABS materials, Hyper ABS makes 3D printing faster and more efficient. Thanks to the fast cooling formula, Hyper Series ABS supports up to 300mm/s print speed with Creality K1/K1 Max/K1C
【Convenient Open Printing】No need warm enclosure and filament dryer box, printing perfect and high precision models which make 3D printing much easier
【High Impact Resistance】Hyper ABS has an impact strength of 19kJ/m², nearly double compared to PLA's 10kJ/m². Its printed models are stronger than PLA's and can be better used for printing parts in stressful environments
【Less Cracking & Warping】Hyper ABS can release stress well during the printing process, thus reducing the shrinkage rate of ABS. No need to close the cavity for printing, it can be successfully printed and effectively avoiding cracking and warping
【Cardboard Spool & Box】Creality Hyper ABS Filament using a fully recyclable cardboard spool and box allows allows convenience for sorting and recycling after the filament is exhausted
