Feature Introduction:
PC K7 is a specialized PC consumable applicable to desktop FDM/FFF. With targeted improvements, it makes enhancement in warping and inadequate interlayer bonding when PC materials apply to desktop printers. Thus, it is applicable to printed products or structural parts which are high strength or require a certain heat resistance temperature.
