Phaetus aeCoating NexPA-GF25 — 25% Glass-Fiber High-Temp Nylon
A high-temperature, glass-fiber-reinforced nylon for stiff, heat-stable functional parts. Phaetus builds it with a co-extrusion skin-core structure: a pure-nylon outer skin wrapped around a core packed with 25% chopped glass fiber. The point of that design is two-fold — the skin gives you clean, pure-resin Z-layer bonding (so you don't lose interlayer strength the way plain GF nylon does), and it keeps most of the abrasive fiber off the nozzle wall.
What it prints well
Functional engineering parts that need to stay stiff and dimensionally stable when warm: brackets, mounts, jigs and fixtures, tooling, motion and drivetrain components, and thin-walled parts that still need real mechanical strength. As-printed tensile strength is ~97 MPa (X-Y), and heat-deflection temperature reaches ~195°C after annealing — well beyond what PETG or ABS will hold.
Hardware you need
- Hardened or DLC nozzle — required. Glass fiber is abrasive. The skin-core layout reduces nozzle wear versus standard GF nylon, but a brass nozzle will still erode. Run hardened steel or DLC. (We sell hardened/DLC nozzles — pair one with this spool.)
- High-temp hotend. Print at 300-340°C; you need an all-metal hotend rated to those temps, ideally with a heater block of 12mm or more for stable flow.
- Enclosure recommended. Cooling fan OFF, bed 70-80°C on PEI (or a swipe of PVP glue stick). An enclosure helps with warp and consistency on a high-temp nylon.

Drying — read this first
Nylon is thirsty. Wet filament oozes, bubbles, and prints rough. Keep the spool in a dry box (humidity under 15%) while you print, and reseal it in the foil bag when you're done. If it has picked up moisture, dry at 80-100°C for 4-6 hours before printing. Optional: anneal finished parts at 80-100°C for 4-8h to push strength and heat resistance higher.
Engineering filament, sold as liquidation stock — factory-sealed. Because it's hygroscopic, dry before use if the seal has been opened.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
