3D Printing Filament Spectrum PA6 Low Warp GF30 Black 1.75 mm 1 kg

Spectrum PA6 Low Warp GF30 Black 1.75 mm 1 kg is a reinforced polyamide (nylon) filament formulated for filament extrusion 3D printing where reduced warpage and increased mechanical performance are required. The filament combines PA6 with 30% glass fiber to deliver higher stiffness, improved dimensional stability and enhanced heat resistance compared with unfilled PA6. It is presented on a 1 kg spool in 1.75 mm diameter and is intended for printers and applications that can process glass-fiber-filled engineering materials.

Advantages

The glass-fiber reinforcement significantly raises tensile stiffness and reduces part deformation during and after printing, while the PA6 base provides good wear resistance and thermal performance. The low-warp formulation helps maintain flatness and dimensional accuracy on larger parts and in multi-layer builds. The 1.75 mm diameter offers consistent feed for standard direct-drive and Bowden extruders when printing with appropriate hardened nozzles and print parameters.

Suitable for

• Functional prototypes requiring higher stiffness and dimensional stability
• Mechanical parts such as gears, housings, brackets and mounts
• Components exposed to elevated temperatures or requiring better creep resistance
• Small-batch production and engineering prototypes

Key specifications

• Material: PA6 (nylon) with 30% glass fiber reinforcement
• Colour: Black
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Reduced warpage formulation for improved dimensional stability
• Increased stiffness and heat resistance compared with unfilled PA6

How to use

Load the 1.75 mm Spectrum PA6 Low Warp GF30 filament into a printer equipped to handle glass-fiber-filled materials and use a hardened steel or similarly wear-resistant nozzle to avoid premature nozzle wear. Recommended extrusion temperatures are typically higher than for standard PLA; adjust print temperature, bed temperature and cooling settings according to printer capabilities and manufacturer guidance. Use an enclosed build chamber where possible to maintain consistent ambient temperature and reduce residual stresses. Ensure proper drying of filament before printing to prevent hydrolysis-related degradation of the polyamide.

Usage recommendations

For best results, dry filament according to the manufacturer’s instructions prior to printing, use a hardened nozzle, enable an enclosed or heated chamber if available, and tune first-layer settings and part cooling to balance surface finish and interlayer adhesion.
