Fiberon™ PA612-CF15

Polymaker’s Fiberon™ PA612-CF15 bridges the gap between traditional PA6 and PA12 polymers by using a long-chain copolyamide matrix reinforced with 15% carbon fiber loading by weight.This specialized chemical structure offers significantly lower humidity sensitivity than PA6-based composites while retaining higher mechanical strength and modulus than PA12 variants.

Featuring a tensile strength of 91.9 MPa and a bending strength of 138 MPa in the XY orientation, this material provides industrial-grade structural performance.Integrated with proprietary Warp-Free™ crystallization control technology, PA612-CF15 minimizes thermal shrinkage during builds, ensuring extreme dimensional fidelity and high inter-layer strength across complex components.

Key Benefits

• 15% short carbon fiber fill for high stiffness and reduced component weight

• Superior moisture resistance compared to standard PA6 and PA6/66 formulas

• Engineered with Warp-Free™ technology for minimal distortion on large builds

• High thermal resistance with HDT reaching up to 175.1°C @ 0.45 MPa

• Outperforms PA12 composites in mechanical strength and flexural modulus

• Clean matte black surface finish that masks build lines effectively

• Excellent inter-layer adhesion for isotropic load distribution

• High-speed motion compatibility up to 300 mm/s

• Stable dimensional accuracy for precision mechanical assemblies

• Consistent extrusion reliability across standard and enclosed FDM platforms

Typical Applications

• Custom end-of-arm robotic tooling and structural grippers

• Industrial manufacturing aids, assembly jigs, and alignment fixtures

• High-stress automotive mounts, brackets, and under-hood housings

• Aerospace and drone structural frames, arms, and motor mounts

• Precision electronic enclosures and protective housings

• Replacement metal structural stock in lightweight assemblies

• End-use functional hardware exposed to humid environments

• Thermal-resistant prototype components operating under mechanical loads

• Mechanical linkages, levers, and load-bearing brackets

  Fiberon™ PA612-CF15 is particularly well suited for structural applications where low moisture sensitivity, high mechanical stiffness, thermal resilience, and dimensional precision are required.
