Polymaker Fiberon PA6-CF20 Nylon Filament

Fiberon™ PA6-CF20 is a carbon fiber reinforced (20%) PA6 (Nylon 6) filament. The carbon fiber provides significantly improved stiffness, strength and heat resistance with outstanding layer adhesion: tensile strength up to 109 MPa and Young's modulus over 8.6 GPa (XY), with heat resistance up to 215°C. Warp-Free™ technology delivers minimal warping and excellent dimensional stability, even on large parts.

Fiberon™ PA6-CF20 is the same great formula as PolyMide™ PA6-CF, although it may print in a slightly darker black shade than its predecessor.

Density: 1.17 g/cm³

Technical Data Sheet (V1.1)

Gear for this filament

You'll want a hardened nozzle for this — glass and carbon fibers eat brass nozzles. The copper-core CHT-style nozzle below also keeps flow up on high-temp materials.
Nylon drinks moisture out of the air — print it from a drybox or dry it first, or you'll print bubbles and stringing no matter how good your tuning is.
