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.

Klipper's pressure advance does most of the ooze control on a Trident, so short fast retraction beats long slow retraction here.

As a self-built machine the Trident's chamber temperature is whatever you have built it to hold, so check it before starting a high-temperature print rather than assuming.

Slicer: OrcaSlicer / SuperSlicer (Klipper). 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.
