Phaetus aeForce™ PAHT-GF Filament 1kg Spool

Phaetus aeForce PAHT-GF is a high-temperature nylon (polyamide) reinforced with 15% chopped glass fiber. It's an engineering filament for functional parts that need stiffness, heat resistance, and dimensional stability — brackets, mounts, jigs, tooling, and machine or automotive components. Compared to plain nylon it warps and shrinks less, and the glass fill adds rigidity and wear resistance while keeping the toughness nylon is known for.

What it prints well

• Stiff, heat-resistant functional parts (PAHT base handles far more heat than PLA/PETG)
• Low warp and low shrinkage for a nylon, with good dimensional stability
• Wear- and chemical-resistant components
• Pairs with Phaetus aeSupport S-PAHT quick-remove support if you need clean overhangs

Print settings

• Nozzle / print temp: 300-320 °C
• Bed temp: 70-90 °C (use an adhesion aid)
• Enclosure: strongly recommended — this is a high-temp engineering nylon; an enclosed, draft-free chamber gives you the layer adhesion and warp control these materials need
• Hotend: must reach and hold 320 °C reliably (Phaetus recommends their Dragon / Dragonfly series, but any all-metal high-temp hotend that hits 320 °C works)

Hardware you need — read this

Glass fiber is abrasive. A brass nozzle will wear out quickly and start under-extruding. Run a hardened-steel, DLC-coated, or ruby nozzle. If you don't have one, add it to your cart — printing GF nylon through brass is a false economy. (We carry hardened and DLC nozzles; see related products.)

Drying — not optional

Glass-filled high-temp nylon is hygroscopic — it pulls moisture from the air fast, and wet filament prints with popping, stringing, weak layers, and a rough surface. Dry it before printing and keep it in a dry box while you print. As a general nylon guideline, dry in a filament dryer or low oven until it runs clean; this spool may have absorbed moisture sitting on a shelf, so dry it first regardless of how it looks.

Clearance stock — sold as-is. Engineering nylon is moisture-sensitive; we recommend drying before first use.
