ASA print settings Acrylonitrile Styrene Acrylate
Essentially ABS engineered for the outdoors: similar strength and heat resistance, far better UV and weather stability, and less odor — but it still warps and wants an enclosure. The go-to for parts that live in sunlight (automotive trim, garden, signage).

What ASA is good (and bad) for
- Outdoor / UV-exposed parts
- Automotive exterior trim
- Weatherproof functional parts
- Anything ABS-grade that also sees sun
- Printing without an enclosure
- Poorly ventilated rooms
Drying & storage
Dry ~70–80 °C for 4–8 h if needed; store sealed with desiccant.
Bed adhesion
Heated bed 75–100 °C in an enclosure; adhesion aid recommended. Keep drafts off the print.
Heat resistance
High, comparable to ABS (glass transition ~100 °C), with much better UV/weather resistance.

ASA FAQ
What temperature do you print ASA at?
Across the 1 ASA filaments in this database, manufacturers recommend nozzle temperatures of 240–260 °C and bed temperatures of 75–95 °C. Exact values are per-brand (see the table); always run a temperature tower on a new spool.
Does ASA need an enclosure?
Yes — ASA warps and can crack without a stable, draft-free chamber. An enclosure (and good ventilation for ABS) is effectively required.
How do you dry ASA?
Dry ~70–80 °C for 4–8 h if needed; store sealed with desiccant.
How heat-resistant is ASA?
High, comparable to ABS (glass transition ~100 °C), with much better UV/weather resistance.
