SUNLU Nylon-6 Glass Fiber (PA6-GF) Filament
SUNLU PA6-GF filament contains 25% glass fiber and boasts high heat resistance up to 214°C (417°F). Engineered for demanding industrial applications with a durable spool that can withstand direct drying up to 110°C, ensuring optimal filament performance straight from the spool.

Handle Extreme Heat
Designed to maintain structural integrity and rigidity at sustained temperatures up to 214°C. Ideal for under-the-hood automotive components, electrical enclosures, and high-temperature industrial tooling.

Superior Chemical Resistance
25% glass fiber ensures strong resistance to aggressive acids, fuels, and industrial solvents. Perfect for chemical valve systems, fuel systems, and corrosion-sensitive industrial gears.

Exceptional Toughness and Strength
Delivers excellent mechanical properties with high impact and drop resistance. Superb layer adhesion ensures prints can withstand rough handling without breaking—engineered for robust industrial applications.

Essential Printing Protocols
-
Drying is Critical: Dry filament for 4 hours at 110 °C immediately after opening and upon exposure exceeding 6 hours.
-
Secure Build Plate Adhesion: Use build plate adhesive (e.g., glue stick) to prevent warping.
-
Protect Your Nozzle: Brass nozzles wear quickly. Mandatory: Use wear-resistant nozzles (e.g., hardened steel).
