IIID Max FiberX PA6/66+CF15 is the filament for makers who need engineering-grade performance. PA6/66 Nylon reinforced with 15% chopped carbon fiber — this is the material for parts that genuinely can't fail.

Combining the flexibility and toughness of Nylon PA6/66 with the stiffness and strength of carbon fiber, FiberX PA6/66+CF15 delivers a material that performs where standard filaments simply won't cut it.

Why engineers and advanced makers choose FiberX PA6/66+CF15:

• Carbon fiber reinforced nylon — outstanding strength-to-weight ratio

• Superior heat resistance — handles high-temperature environments

• Reduced warping vs. standard nylons — carbon fiber improves dimensional stability

• Impact and abrasion resistant — built for demanding mechanical applications

• Reduced moisture absorption vs. standard PA6/66

• Smooth surface finish suitable for precise, functional end-use parts

• Use a hardened steel or wear-resistant nozzle (0.4mm+)

Perfect for: aerospace jigs, automotive brackets, structural components, industrial tooling, and any application where regular filaments just don't hold up.
