 Printing Notes

PA6-CF is the strongest filament OzFDM sells — 60 – 65 MPa tensile and a 4900 – 5000 MPa flexural modulus, with a 200 °C heat deflection temperature.

It demands a hardened nozzle, a hot chamber and genuinely dry filament. Treat any one of those as optional and the print will fail.

The X1C ships with a hardened steel nozzle and a fully enclosed chamber, so it needs none of the modifications other machines do for this material.

Bambu Studio's own generic profile is a reasonable starting point, but its temperatures are set for Bambu filament — use the figures above for OzFDM spools.

Slicer: Bambu Studio / OrcaSlicer. Dry the filament at 80 °C / ≥ 12 h before a long print — every figure above assumes dry filament.

 Troubleshooting

Steam, popping and a furry surface — PA6 absorbs about 1 % moisture. Dry twelve hours at 80 °C and feed from a sealed dry box during the print.

Layers separating under load — Nozzle too cool for the speed. Push to 290 °C and slow to 40 mm/s — layer bonding in nylon is heat-driven.

Parts distorting after they come off the bed — PA6 continues to absorb moisture and grows slightly. Anneal, then condition the part before measuring it.
