Fiberon™ PA6-GF25 is a glass fiber reinforced PA6 (Nylon 6) filament containing 25% glass fiber by weight. It delivers excellent mechanical strength, high stiffness, and heat deflection up to 191°C after annealing — without sacrificing layer adhesion. Warp-Free™ technology allows printing at lower bed temperatures with minimal warping, and no heated chamber is required.
Formerly called PolyMide™ PA6-GF — same trusted formula, now under the Fiberon™ brand.

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.
