ASA

How do I print ASA successfully?

Q: How do I print ASA successfully?

Print ASA in a draft-free enclosure with ventilation, and use the nozzle and bed on that spool's catalog row when the part lives outdoors or in a car.

First in this ranking: Bambu Lab ASA.

Treat ASA as the outdoor ABS-class print. Keep drafts off the part, ventilate the room, and read the spool row before you type a temperature. ASA is the material hub.

Nozzle and bed

Bambu Lab ASA, PolyLite ASA, and ELEGOO ASA each list 235–260 °C (455–500 °F) and 90–110 °C (194–230 °F). Prusament ASA lists 250–270 °C (482–518 °F) and 100–120 °C (212–248 °F). The editorial 240–260 °C (464–500 °F) band is not a fifth row. ABS printing uses the same enclosure process on ABS rows that list 230–260 °C (446–500 °F).

Ventilation

A comment on r/prusa3d 1lsmbru says the setup can work and still asks for real ventilation, because styrene is bad. That is the fume note. This page does not add a chamber temperature.

Outdoors and cars

Use ASA when the part lives in the sun or in a car. Outdoor filament ranks ASA first. Can PLA be used outdoors? is the PLA-specific limit. A comment on r/3Dprinting 1vsqef3 answers yes to ASA for outdoor sun, no cover, and a load. Neither page publishes a UV-hours test.

Drying and warp

Bambu ASA lists drying at 80 °C (176 °F) for 8 h. The other three rows do not. Drying is the general method. Warping is corner lift on ABS and ASA. The bank also lists r/BambuLab 1vj3wsm, 1f4vmbq, and 1iea7jq. The supplied excerpts do not include a temperature from those three threads.

Pros and cons

Pros

The outdoor and in-car use is why this material is on the list. UV resistance is the role, and the catalog does not store a UV-hours number.
Three rows share 235–260 °C (455–500 °F) and 90–110 °C (194–230 °F). Prusament ASA is listed separately because it does not.

Cons

The editorial summary says 240–260 °C (464–500 °F) and a 90–110 °C (194–230 °F) bed. This page does not publish 240–260 °C (464–500 °F) as an ASA fact. The 235 °C (455 °F) rows start lower, and Prusament ASA is 250–270 °C (482–518 °F).
Drying at 80 °C (176 °F) for 8 h belongs to the Bambu ASA sheet. PolyLite ASA, ELEGOO ASA, and Prusament ASA do not list it.

Printer considerations

Enclosure required is blank on these rows. A draft-free chamber is the process in the first sentence, the same process as ABS, and it is not a filled catalog cell.
Ventilate. A comment on r/prusa3d 1lsmbru says styrene is bad and the room the box is in needs real ventilation.
Check the printer's maximum nozzle and bed before Prusament ASA. That row is 250–270 °C (482–518 °F) and 100–120 °C (212–248 °F).

Printer limits

What the community says

The editorial summary says ASA prints like ABS, with an enclosure, 240–260 °C (464–500 °F), and a 90–110 °C (194–230 °F) bed, and that it is the outdoor and in-car material. The bed band matches the Bambu, PolyLite, and ELEGOO rows. The nozzle band does not match them, and it does not match Prusament ASA. A comment on r/3Dprinting 1vsqef3 treats outdoor sun, no cover, and a load as a reason to move off PLA. A comment on r/prusa3d 1lsmbru asks for ventilation because styrene is bad. The bank's caveats field is empty.

Questions

Is the ASA nozzle always 240–260 °C (464–500 °F)?

No. Bambu Lab ASA, PolyLite ASA, and ELEGOO ASA each list 235–260 °C (455–500 °F). Prusament ASA lists 250–270 °C (482–518 °F). The 240–260 °C (464–500 °F) line is the editorial summary. It is not copied into the table.

Does the catalog mark these ASA spools as enclosure-required?

No. Enclosure required is blank. A draft-free enclosure and ventilation are the process. The 8 h dry at 80 °C (176 °F) is the Bambu ASA sheet only.
