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 K1 is enclosed and runs Klipper, so pressure advance handles most oozing and retraction can stay short.

Its bed tops out at 100 °C, which is the one real constraint when printing the higher-temperature materials in this range.

The 110 °C on the data sheet is above this printer's 100 °C bed maximum, so 100 °C is the working figure. Use a brim and keep draughts off the machine to make up the difference.

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.
