Bambu Lab PA6-GF Glass-Fibre Nylon Filament — 1.75 mm, 1 kg

PA6-GF is Bambu Lab’s glass-fibre reinforced nylon 6 — an engineering filament for the jobs PLA and PETG quietly fail at. The chopped glass fibre dispersed through the PA6 matrix lifts stiffness and dimensional stability well above unfilled nylon while keeping nylon’s standout traits: toughness, self-lubricating low friction and genuine heat resistance, with a heat deflection temperature of 186 °C. It also prints far more predictably than plain PA6, because the fibre reinforcement dramatically reduces the warping and shrinkage that make raw nylon frustrating.

This is the material for end-use functional parts: gears and bushings, drone and RC frames, tooling and workshop jigs, motor mounts, brackets, hinges and under-bonnet automotive components. It’s well suited to enclosed printers such as the Bambu Lab X1 series, P1S, P2S and H2 series, and works on any 1.75 mm FDM printer that can reach 290 °C at the nozzle and hold a warm chamber. Because glass fibre is abrasive, a hardened steel nozzle in 0.4 mm or larger is mandatory — a 0.6 mm hardened nozzle is the sweet spot for flow and part strength. Standard brass or stainless steel nozzles will wear out quickly.

Print Settings Guidance

• Nozzle temperature: 260–290 °C — start at 280 °C and tune for layer adhesion
• Bed temperature: 80–100 °C, with glue stick on a smooth PEI or engineering plate for adhesion and easy release
• Print speed: up to 130 mm/s; slower outer walls give cleaner surfaces on fibre-filled material
• Part cooling: keep it low — nylon relies on slow cooling for interlayer strength. Exact fan percentage: [VERIFY]
• Chamber: enclosed printer recommended; a warm chamber reduces warping on tall parts. Recommended chamber temperature: [VERIFY]
• Nozzle: hardened steel, 0.4 mm minimum (0.6 mm recommended). Not suitable for brass or stainless steel nozzles
• Drying before use: 80 °C for 8–12 hours in a blast drying oven, or 90–100 °C for 10–12 hours on a heat bed. Never exceed 100 °C — the spool can deform

Practical Tips

Dry it, then keep it dry. Nylon is one of the thirstiest filaments there is — PA6-GF will pull moisture out of the air in hours, not days, and Australian coastal humidity is unforgiving. Wet nylon prints with steam popping, stringing, a rough furry surface and badly weakened layers. Dry the spool before every serious print and run it straight from a filament dryer or a sealed drybox with fresh desiccant, keeping storage humidity under 20% RH.

Design and finish for the fibre. Glass fibre boosts stiffness along the layer, so orient parts to put loads across the walls rather than pulling layers apart, and add extra wall loops instead of high infill for stronger functional parts. Apply a thin, even coat of glue stick to your build plate — it both improves first-layer grip and protects the plate surface. And check your nozzle: if you’ve been printing filled materials for a while, a worn nozzle is the usual culprit behind sudden under-extrusion.

Nour Engineering Solutions accepts returns or refunds for change of mind or wrong items ordered within 30 days from the purchase date. Customers need to return the items to Nour Engineering Solutions, ensuring the items are in brand new, unused condition. Customers will also be charged for the cost of the original shipping and a re-stocking fee equal to 10% of the order value.

In case of items arriving damaged or wrong items being sent to the customer, Nour Engineering Solutions will be responsible for either exchanging stock for the customer or issuing a refund.

In the case of defective returns, refunds will only be issued after the items are returned to Nour Engineering Solutions. Nour Engineering Solutions will be responsible for the return postage, and the customer should provide reasonable assistance for the defective items to be picked up by courier, such as packing the items and printing shipping labels.

Once the order is dispatched, it is the customer’s responsibility to follow up the shipment. If the items arrive damaged, the customer should notify Nour Engineering Solutions within 2 business days after receiving the order. If the item does not arrive within 2 business days of the expected delivery date, the customer should notify Nour Engineering Solutions immediately. Nour Engineering Solutions may refuse to refund or exchange items if the customer fails to do so.

In case the first delivery attempt is unsuccessful, the parcel will be forwarded to the local Post Office or News Agency. Failure to pick up parcels within the required timeframe may result in the parcel being returned to Nour Engineering Solutions. In this case, customers will be responsible for the costs associated with re-sending the parcel.
