Polymaker PolyMide PA6-CF Filament

PolyMide™ PA6-CF

PolyMide™ is a family of Nylon/polyamide based filaments. Produced with Polymaker’s Warp-Free™ technology, PolyMide™ filaments deliver engineering properties intrinsic to Nylon and ease of printing.

PolyMide™ PA6-CF 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.

We highly recommend to use a wear resistant nozzle, to print with the PolyBox™ and to keep it at dry conditions (relative humidity of 15% or less) at all times to maintain the best printing results.


Excellent Stiffness & Strength - Featuring a tensile modulus of 7.4 GPA on the XY axis and 4.3 GPA on the Z axis, PolyMide™ PA6-CF is well suited for high performance industrial and engineering applications. PolyMide™ PA6-CF combines extreme stiffness and best-in-class tensile strength.

Excellent Heat Resistance - Featuring a heat deflection temperature of up to 215°C, this material lends itself perfectly to functioning automotive applications where strength and heat resistance are required.

Outstanding Layer Adhesion - All other brands of fiber reinforced material show a decrease in z-axis layer adhesion when compared with their non-fiber reinforced Nylons, producing a part that is only stronger on the X-Y axis but detrimental to the Z axis. Polymakers new technology in PolyMide™ PA6-CF not only solves this problem but actually increases Z axis tensile strength creating more isotropic parts that are strong in every direction.

Wear Resistant and Tough - Parts printed in PolyMide™ PA6-CF display excellent toughness and wear resistant properties.

ESD Safe - PolyMide™ PA6-CF is an ESD safe material making it a suitable candidate for printing electronic jigs and fixtures

Improved Printability – Unlike many other Nylon filaments, PolyMide™ PA6-CF is extremely easy to work with, exhibiting excellent dimensional stability. It is compatible with most filament-based 3D printers with no heated bed or chamber required!

Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches.

PolyMide™ PA6-CF Features Fiber Adhesion™ and Warp-Free™ technology

Warp-Free™ - Warp-Free™ technology enables the production of Nylon-based filaments that can be 3D printed with excellent dimensional stability and near-zero warpage. This is achieved by the fine control of microstructure and crystallization behaviour of Nylon, which enables the material to fully release the internal stress before solidification. The Warp-Free™ technology in PolyMide™ PA6-CF is designed to work best with minimal bed temperatures.

Fiber Adhesion™ - Fiber Adhesion™ technology improves the layer adhesion of fiber reinforced materials, by optimizing the surface chemistry of the fibers to achieve better dispersion and bonding to the matrix. This results in better strength along the Z-axis and reduced mechanical anisotropy.
