3D printer filament POLYMAKER Filament Fiberon PA6-GF25 FG02001 25% glass fiber, high-strength polyamide

POLYMAKER Filament Fiberon PA6-GF25 FG02001 is a polyamide (PA6) based 3D printing filament reinforced with 25% glass fiber, engineered for applications that require elevated stiffness, strength and dimensional stability. The composite formulation reduces deformation and improves wear resistance compared with unfilled PA6, making it suitable for functional prototypes, end-use mechanical parts and engineering components. This filament is intended for use on FFF/FDM printers that can reach the high extrusion temperatures and handle abrasive, fiber-filled materials.

Advantages

The glass fiber reinforcement increases tensile strength and flexural stiffness while maintaining the thermal and chemical resistance characteristics of polyamide. Improved dimensional stability reduces warping and shrinkage in larger or thin-walled prints. The material offers enhanced wear resistance and mechanical durability for moving parts and load-bearing components. It is formulated to provide reliable layer adhesion and consistent extrusion when appropriate printer settings and hardened hardware are used.

Suitable for

• Functional prototypes and demonstration parts that require mechanical strength
• Gears, bearings, bushings and wear-resistant moving components
• Structural fixtures, jigs and assembly aids used in manufacturing
• End-use parts exposed to moderate heat, friction or mechanical load

Key specifications

• Base polymer: PA6 (polyamide)
• Reinforcement: 25% glass fiber by weight
• Material type: fiber-reinforced engineering filament for FFF/FDM
• Mechanical properties: increased stiffness and tensile strength versus unfilled PA6
• Thermal behavior: improved dimensional stability and heat resistance consistent with polyamide
• Abrasiveness: contains glass fiber; may require hardened steel or ruby nozzle
• Surface finish: matte, fiber-textured appearance after printing

How to use

Print this PA6-GF25 filament on a printer capable of high-temperature extrusion and with a heated build platform. Use a hardened steel or other abrasion-resistant nozzle and a direct or well-calibrated Bowden feed to reduce filament wear. Set extrusion temperatures and bed temperatures according to printer and filament guidance for PA6 composites, and enable part cooling conservatively to retain layer adhesion. Apply an appropriate build surface or adhesive to improve first-layer adhesion and consider printing an enclosure or using ambient temperature control to limit warping on larger parts.

Usage recommendations

Recommend monitoring nozzle wear regularly, storing filament in dry conditions to prevent moisture uptake, and drying the filament before printing if necessary. Adjust print speed and retraction settings to balance surface quality and mechanical performance; validate settings with test prints before producing critical parts.
