• Keep retraction minimal like ABS. ASA is more prone to stringing than ABS but less than PETG.

 Printing Notes

ASA is the outdoor material. It holds colour and impact strength under Australian UV where ABS chalks and yellows within a season.

It is more impact-resistant than ABS, 19 – 20 kJ/m² against 7 – 10.5, and warps slightly less, but it still needs an enclosure.

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, so use the figures above for OzFDM spools.

Slicer: Bambu Studio / OrcaSlicer. Dry the filament at 80 °C / ≥ 5 h before a long print. Every figure above assumes dry filament.

 Troubleshooting

Warping despite an enclosure. ASA runs hotter than ABS. Take the bed to the top of what your machine allows and let the chamber come up to temperature before the print starts, not during it.

Weak layer bonding. Cooling is on. ASA wants the fan off entirely except for bridges.

Surface blistering or bubbling. Damp filament. Dry at 80 °C for at least five hours. ASA's listed moisture absorption is 0.35 % at 23 °C and 50 % relative humidity, at equilibrium.
