ELEGOO PLA-CF Filament (sort)ELEGOO PLA CF Filament (black) ELEGOO PLA CF (polylactide doped with carbon fiber) filament combines the ease of printing typical of PLA (polylactide a plant derived, biodegradable plastic) with higher mechanical strength. The addition of carbon fiber increases the stiffness of the material and reduces its shrinkage during cooling, resulting in greater dimensional precision. This type of material works well in technical components, housings and
