PA+GF (Nylon + Glass Fiber) is a high-performance engineering composite designed for both FFF (Fused Filament Fabrication) and FGF (Fused Granulate Fabrication) 3D printing. By combining the toughness of nylon (polyamide) with the enhanced rigidity of glass fibre reinforcement, PA+GF delivers exceptional mechanical strength, wear resistance, heat resistance, and dimensional stability. It is widely used for functional prototypes, industrial tooling, automotive parts, and structural engineering components.

PA+GF is one of the most reliable 3D printing materials for industrial additive manufacturing, offering outstanding performance in demanding environments. Glass fibre reinforcement significantly improves the stiffness and load-bearing capacity of standard nylon while reducing warping and deformation during printing. Available as both filament for FFF printers and pellets for FGF systems, PA+GF enables manufacturers to produce durable, high-quality components for small precision parts and large-format industrial applications.

Why Choose PA+GF for 3D Printing?

PA+GF is engineered for applications where strength, durability, and long-term reliability are essential. It combines the flexibility and toughness of nylon with the structural reinforcement of glass fibres, resulting in components capable of withstanding continuous mechanical stress, abrasion, and elevated temperatures. This makes PA+GF a preferred material for engineering, manufacturing, and industrial production.

Compatible Printing Technologies

PA+GF is fully compatible with both industrial additive manufacturing technologies offered by GFac.

FFF (Fused Filament Fabrication)

FFF technology uses PA+GF filament to manufacture highly accurate engineering components with excellent surface quality and dimensional precision. It is ideal for functional prototypes, mechanical assemblies, industrial fixtures, and low-volume production parts where accuracy and strength are critical.

FGF (Fused Granulate Fabrication)

FGF technology processes PA+GF pellets, enabling manufacturers to produce large-format components at higher printing speeds and lower material costs. It is particularly suitable for automotive tooling, heavy-duty industrial fixtures, structural components, moulds, marine applications, and large engineering parts.

Both technologies deliver excellent mechanical performance, allowing manufacturers to select the best solution based on component size, production volume, and manufacturing efficiency.

Storage and Best Practices

PA+GF is a hygroscopic material, meaning it readily absorbs moisture from the surrounding environment. To maintain optimal print quality and mechanical performance, store both filament and pellets in a sealed container with desiccant. If moisture has been absorbed, dry the material before printing. For the best results, use an enclosed printer to improve temperature stability and minimise warping. Because glass fibres are abrasive, a hardened steel or wear-resistant nozzle is recommended to reduce nozzle wear and ensure consistent long-term printing performance.
