Wear resistantImpact resistantStrongFunctional

Glass fiber nylon (PA-GF) reinforces nylon with chopped glass fiber, increasing stiffness, heat resistance, and dimensional stability well beyond unfilled nylon. Compared to carbon fiber nylon, glass fiber offers roughly a third to half the stiffness improvement, but consistently retains significantly better impact resistance and toughness. Glass fiber composites tend to deform somewhat before failing rather than cracking suddenly, and handle repeated stress or vibration better over time. PA-GF is also notably cheaper than carbon fiber nylon, doesn't conduct electricity, and can be dyed in a range of colors, unlike carbon fiber's characteristic black. Glass fiber nylon suits automotive prototypes, structural brackets, industrial jigs and fixtures, and housings near heat sources where cost-effective rigidity matters more than minimizing weight.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

Standard

12 colors

The standard (as-printed) finish on FDM parts shows the natural texture of layer-by-layer printing. The visibility of the layer lines depends on part geometry and orientation, plus light marks where support material was removed.

Sanded

Sanded

12 colors

The sanded finish on FDM parts reduces the visibility of layer lines compared to the standard finish, though some surface texture generally remains. How much smoothness is achieved can vary depending on the material.
