Raise3D Hyper Core ABS CF15 Filament (1.75mm): Black - 2.5kgRaise3Ds Hyper Core ABS CF15 filament is specially formulated using unique extrusion technology to create a fiber rich inner core where the majority of carbon fibers are aligned and evenly distributed. During high speed FFF printing, the exceptional heat conductivity of the carbon fiber core speeds up filament melting in the hot end. Additionally, the residual thermal energy of the fiber rich inner core enhances the interlayer bonding of ABS between
