<

【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.
【Safer and More Environmentally Friendly】Hyper ABS is made from lower residual monomer materials and is formulated and manufactured to reduce volatiles from thermal decomposition to protect your health.
