SUNLU Nylon PA6-GF — Glass Fiber Reinforced Nylon

SUNLU Nylon PA6-GF is an engineering-grade PA6 nylon reinforced with 25% glass fiber. What sets this line apart is its stiffness and heat resistance up to 214°C while keeping high impact toughness — parts hold their shape under load and heat where plain PLA or PETG would soften long ago. It's built for functional parts: automotive brackets, electronics housings, drone motor mounts, and industrial tooling.

Print Settings

• Nozzle temperature: 270–290°C
• Bed temperature: 50–70°C, apply a glue stick to the bed to fight warping
• Print speed: 50–120 mm/s
• Drying is mandatory: 4 hours at 110°C right after opening and after more than 6 hours of exposure
• Glass fiber makes the filament abrasive — a hardened nozzle is required

This line suits makers who need strong, heat-resistant parts: working prototypes, repair brackets, under-hood components, and load-bearing assemblies. Print it on a machine with an enclosure, heated bed, and high-temperature hotend — such as the Bambu Lab X1 series or H2D. The spool fits most printers thanks to standard dimensions.
