Material Information

Name: PA6CF20
Source: Plural Additive Manufacturing

PA12CF20 is a carbon fiber reinforced PA6 (Nylon 6) filament. The carbon fiber reinforcement provides significantly improved stiffness, strength and heat resistance with outstanding layer adhesion. This material can operate in extremely demanding applications in the automotive, scientific, and engineering industries. It is an ESD safe material which outperforms almost all other 3D printing filaments in terms of strength, rigidity, impact resistance and heat resistance.

    • PA6CF20 is a polyamide 6 based material which makes it very hygroscopic. This means that it is susceptible to absorbing moisture from the atmosphere which can subsequently affect the quality and mechanical properties of the final prints. We recommend storing it in an MMS, PolyBox or Print Dry to prevent moisture absorption. If the filament has absorbed moisture, it will need to be dried before printing. It should always be stored and used under dry conditions (relative humidity below 20%).
    • PA6CF20 contains 20% chopped carbon fibers by weight, which makes it very abrasive. It is important to have anti-abrasive (hardened) nozzles installed while printing. PA6CF20 can easily damage brass nozzles after a few hundred grams of printing.

    • We recommend annealing all models printed in PA6CF20. This allows users to take advantage of the full mechanical and thermal properties of this material. The annealing process consists of putting the model in an oven at 90˚C for 2 hours.
