Polymaker PA612-CF filament is a cutting-edge material for FDM 3D printing. Merging the resilience of Polyamide 612 with the toughness of carbon fibre, this filament is tailored for high-demand tasks, including aerospace components and engineering prototypes. Beyond its robustness, its unique matte and textured finish sets it apart.

Physical Properties

Note: The specific data on physical properties may vary depending on the manufacturing batch and post-processing methods. However, carbon fiber reinforced materials like PA612-CF generally exhibit:

  • Tensile Strength: Significantly higher than standard PA612, often exceeding 100 MPa
  • Heat Deflection Temperature (ISO 75 0.45MPa): 175 °C
  • Density: Typically higher than standard PA612 due to carbon fiber, around 1.3–1.4 g/cm³

Aesthetic Quality

Polymaker PA612-CF usually comes in a matte black color due to the presence of carbon fibers. The material can produce parts with a high-quality finish, capturing fine details effectively. The carbon fibers give it a textured appearance that’s quite distinct from standard thermoplastics.

Durability and Usage

Polymaker PA612-CF is engineered for applications that demand high strength, stiffness, and thermal stability. It’s particularly suitable for:

  • Aerospace and automotive parts
  • Engineering prototypes
  • High-performance gears and fixtures
  • Components that need to resist chemicals and environmental factors


Typical post-processing steps include sanding, machining, or even chemical treatments for smoothing or improving the surface finish. Carbon fiber reinforced materials usually respond well to these processes, but specialized tools may be needed to handle the added hardness and abrasiveness of the fibers.

Environmental Impact

Carbon fiber reinforced materials like PA612-CF are not biodegradable and require special recycling processes. These materials are synthesized from non-renewable resources, making them less eco-friendly compared to bio-based materials such as PLA.

In summary, Polymaker PA612-CF offers an advanced, high-performance material that combines the excellent properties of PA612 with the strength and stiffness of carbon fiber. Although it is not the most environmentally friendly option, its superior mechanical properties make it invaluable for demanding industrial and engineering applications. Specialized post-processing and disposal methods may be needed due to the composite nature of the material.
