Polymaker Fiberon PA6-GF25 Glass Fiber Nylon Filament 1.75mm, Grey, 0.5kg

Product Details

• Strong Nylon for Load-Bearing Parts: PA6-GF25 combines 25% glass fiber reinforcement with Nylon 6 to provide high strength, stiffness, impact durability, and layer adhesion for brackets, housings, jigs, fixtures, automotive components, and mechanical parts.
• Engineered Heat Performance: After annealing at 100°C for 16 hours, test specimens reach an HDT of 191°C at 0.45 MPa and 157°C at 1.8 MPa. These results are not continuous-use temperature ratings; actual performance depends on load, geometry, moisture, print orientation, and processing conditions.
• Keep Dry Before and During Printing: Nylon 6 absorbs moisture, which can reduce stiffness and strength while increasing flexibility. Store and print below 20% relative humidity. If exposed to moisture, dry at 100°C for 10 hours and print directly from a dry box when possible.
• Use an All-Metal Hotend and Hardened Nozzle: Print at 280–300°C with a 40–50°C build plate and the cooling fan off. Do not exceed the recommended bed temperature, as excessive heat may increase warping. A heated chamber is not required. Speeds up to 300mm/s are possible after calibration.
• Important Post-Printing Guidance: Anneal printed parts at 100°C for 16 hours when maximum thermal and mechanical performance is required. Remove same-material supports before the part absorbs excessive moisture, as the supports may become difficult to separate. Validate dimensions after annealing.

Printing Polymaker Nylon-GF

Polymaker Nylon-GF in Grey runs on the standard Nylon-GF profile below, and this listing is a 0.50kg spool. Nylon-GF is best suited to tough, wear-resistant mechanical parts like gears, hinges, and high-heat brackets. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
