Bambu Lab ASA
Manufactured by Bambu Lab
Quick Summary
Bambu’s ASA is a clean, well-behaved version of a material that punishes sloppy setups. It prints at 240-270 °C with an 80-100 °C bed inside a 45-60 °C chamber, and it produces outdoor parts that still look right after a summer on a south-facing wall. If your printer is enclosed, this is one of the easiest ASAs to run. If it is not, no setting will save you.
Print Settings That Work
255 °C nozzle, 90 °C bed, part cooling off or barely on, enclosure closed and warmed through before the first layer. Let the chamber come up to temperature by printing a purge tower or simply waiting; a cold start on a tall part is the classic way to lose four hours.
Glue stick on textured PEI, always. ASA sticks well when it wants to and lifts a corner when the chamber dips, and the adhesive is cheap insurance. A brim on large flat footprints is worth the extra plastic.
Print Quality
Surfaces come out satin and uniform, with the slight softness that comes from printing without part cooling. Detail is a little rounder than PETG at the same layer height, which suits functional parts and disappoints on miniatures.
The material sands and drills nicely, and it accepts paint better than PETG. Layer adhesion is strong in a warm chamber, and the parts are genuinely tough: a bracket bends and springs back where PLA would shatter.
Annealing at 80-90 °C for several hours relieves internal stress and is worth doing on anything that will get hot in service.
Where It Falls Short
Warping is the permanent hazard, and the chamber requirement rules out most open-frame printers. Fumes need ventilation. Bed adhesion is the weakest score in this review and needs help from glue on every print.
Price sits above Polymaker’s PolyLite ASA for the same working window, and outside a Bambu machine the RFID advantage is wasted.
Verdict
For garden brackets, car interior parts, sensor housings, and anything that will see sun, Bambu ASA is a good choice and an easy one if you own an enclosed printer. On an open frame, print PETG and accept the lower heat and UV rating rather than fighting a material that will crack at hour three.
- Bambu Lab ASA vs polylite asa — Polymaker PolyLite ASA is the cheaper equivalent with the same handling; Bambu ASA is the pick inside an AMS thanks to RFID tracking.
- Bambu Lab ASA vs prusament asa — Prusament ASA has the finest surface and tightest tolerance of the three; Bambu ASA prints faster and costs less.
- Bambu Lab ASA vs bambu abs — Same family of problems and roughly the same price. Choose ASA whenever the part sees daylight.
What temperature should I print Bambu ASA at?
The data sheet specifies 240-270 °C at the nozzle, an 80-100 °C bed and a 45-60 °C chamber. 255 °C nozzle, 90 °C bed, cooling off, enclosure closed is a good working profile.
Is ASA harder to print than ABS?
Marginally easier, in practice. The two shrink about the same amount, but ASA is slightly less prone to cracking mid-print and smells less. Both need an enclosure for anything taller than a few centimetres.
How long does ASA last outdoors?
Years, in the sense that matters. UV stability is the whole point of the material: colour and surface hold up where ABS yellows and PLA goes brittle within a season.
