What filaments can the Bambu A1 / A1 mini print?

Q: What filaments can the Bambu A1 / A1 mini print?

PLA, PETG, and TPU fit the stored A1 and A1 mini nozzle and bed limits. ABS and ASA list beds that run past the A1 maximum of 100 °C (212 °F) and the A1 mini maximum of 80 °C (176 °F), and the A1 poster says they cannot print ABS because the machine has no enclosure.

First in this ranking: Bambu Lab PLA Basic.

PLA Basic technical data sheet. Nozzle 190–230 °C (374–446 °F), bed 35–45 °C (95–113 °F), drying at 50 °C (122 °F) for 8 h. Both ends sit under the A1 hotend of 300 °C (572 °F) and the A1 bed of 100 °C (212 °F), and under the A1 mini bed of 80 °C (176 °F).
2	Bambu Lab · PETG HF	PETG	230–260 °C (446–500 °F)	65–75 °C (149–167 °F)	Datasheet	Amazon ↗
PETG HF technical data sheet. Nozzle 230–260 °C (446–500 °F), bed 65–75 °C (149–167 °F), drying at 65 °C (149 °F) for 8 h. The bed fits the A1 and the A1 mini. r/BambuLab 1ke4vl6 is an A1 PETG print the top comment calls wet, and a reply says the PETG HF store page warns to dry it.
3	Bambu Lab · TPU for AMS	TPU	220–240 °C (428–464 °F)	30–35 °C (86–95 °F)	Datasheet	Amazon ↗
TPU for AMS technical data sheet. Nozzle 220–240 °C (428–464 °F), bed 30–35 °C (86–95 °F), drying at 70 °C (158 °F) for 8 h, print speed up to 130 mm/s. The A1 and A1 mini records list AMS lite. The TPU threads below are about generic TPU feeding, not a test of this spool in the AMS.
4	Bambu Lab · TPU 90A	TPU	200–250 °C (392–482 °F)	30–35 °C (86–95 °F)	Datasheet	Amazon ↗
TPU 90A. Nozzle 200–250 °C (392–482 °F) and bed 30–35 °C (86–95 °F). The record lists a drying maximum of 70 °C (158 °F) for 8 h. Shore hardness on the row is 90A, which is the hardness named in the A1 TPU comments. The drying guide keeps a community TPU band of 50–55 °C (122–131 °F) separate from this 70 °C (158 °F) maximum.

Match the spool to the A1 or A1 mini you have. The two machines share a 300 °C (572 °F) hotend and a stainless steel nozzle. They do not share a bed maximum.

PLA and PETG

PLA Basic lists 190–230 °C (374–446 °F) and a bed of 35–45 °C (95–113 °F). That bed fits the A1 maximum of 100 °C (212 °F) and the A1 mini maximum of 80 °C (176 °F).

PETG HF lists 230–260 °C (446–500 °F) and a bed of 65–75 °C (149–167 °F), with drying at 65 °C (149 °F) for 8 h. On r/BambuLab 1kplic3 the poster cannot print ABS and asks if PETG will survive in a car. Replies treat sun on the part as the risk, and two of them report multi-year PETG parts in vehicles. Those are anecdotes. PETG and PLA are the material pages. The enclosed P1S and X1 Carbon comparison is what those machines print.

On r/BambuLab 1ke4vl6 the leading comment tells the A1 owner to dry the PETG. A reply says leftover PLA in the hotend and PETG do not mix.

TPU

r/BambuLab 1lyrd5i and r/BambuLab 1jrz7xv are first TPU prints. The practical replies are a generic TPU profile, a dry spool, a short PTFE path, and a dry box. One reply says not to feed TPU straight out of a running dryer because it gets too soft. TPU for AMS lists 220–240 °C (428–464 °F), a bed of 30–35 °C (86–95 °F), and drying at 70 °C (158 °F) for 8 h. TPU 90A lists 200–250 °C (392–482 °F) and the same 30–35 °C (86–95 °F) bed. Read which filaments work in the AMS, TPU on a Bambu printer, and Bambu filament before you put a flexible spool in the hub.

Plate advice in these threads disagrees. One reply says a smooth plate without glue will tear when TPU is pulled off. The leading reply on r/BambuLab 1ngnb0h wants smooth PEI plus glue because textured PEI grips too hard. Another reply printed 90A on textured PEI with no glue. A reply on that plate thread says TPU does not need an enclosure, and that a closed chamber should be opened so the filament does not soften before the extruder.

ABS and ASA

Bambu ABS and Bambu ASA each list a bed of 90–110 °C (194–230 °F). The A1 bed stops at 100 °C (212 °F). The A1 mini bed stops at 80 °C (176 °F), which is under the bottom of that range. The poster on 1kplic3 says the A1 has no enclosure, so they are not printing ABS. A score-19 reply disagrees and says to avoid drafts. This page does not turn that reply into a small-part ABS recipe. The Bambu Lab brand index is the rest of the spool list.

Pros and cons

Pros

PLA, PETG, and TPU are checked against the stored A1 and A1 mini maxima.
The TPU plate comments are reported as a disagreement, including glue on smooth PEI and a 90A print on textured PEI with no glue.

Cons

The A1 record does not say the frame is open. The no-enclosure line is the poster's statement on r/BambuLab 1kplic3.
A score-19 reply says ABS printed on an Ender 3 V2 and that an A1 can print ABS if drafts are avoided. The Bambu ABS bed of 90–110 °C (194–230 °F) still runs past both stored bed maxima.

Printer considerations

The A1 FAQ stores a 300 °C (572 °F) hotend, a 100 °C (212 °F) bed, and a pre-installed 0.4 mm stainless steel nozzle. Hardened steel is sold separately. The FAQ does not call the frame open or enclosed, so enclosure on the printer record is empty.
The A1 mini technical specifications store a 300 °C (572 °F) hotend, an 80 °C (176 °F) bed, and a stainless steel nozzle. The FAQ says a hardened steel nozzle is required for carbon-fiber or glass-fiber filament and is not the pre-installed nozzle.
A comment on the A1 mini plate thread names about 50 °C (122 °F) for a smooth patterned plate. That figure is above the 30–35 °C (86–95 °F) bed on both ranked TPU rows.

Printer limits

What the community says

r/BambuLab 1kplic3 is an A1 part for a car. The poster says they cannot print ABS because there is no enclosure and asks whether PETG will survive. The leading comment says the cabin-air risk is the sun eating the part. Two replies report PETG parts that have lasted years in a vehicle, one of them in Texas heat, and one of those replies says a headrest hanger still holds 5 kg water bottles. A score-22 reply says ABS or ASA would hold up better in a hot car and that PETG is a better trial than PLA. A score-19 reply says ABS is possible on an A1 if drafts are avoided. r/BambuLab 1lyrd5i and 1jrz7xv are first TPU prints on the A1 and A1 mini. The leading reply on 1lyrd5i is to load TPU, choose a generic TPU profile, and print. Replies disagree on glue: one says never print TPU on a smooth plate without glue, one always uses glue on textured PEI, and one printed 90A on textured PEI with no glue. Drying replies say to dry TPU, keep the PTFE path short, print from a dry box, and not to print out of a dryer because the filament gets too soft. r/BambuLab 1ke4vl6 is rough A1 PETG. The leading comment says to dry it. A reply says PLA residue and PETG do not mix. r/BambuLab 1ngnb0h is TPU stuck too hard to textured PEI on an A1 mini. The leading reply is smooth PEI plus glue as an interface. A reply says TPU does not need an enclosure and that a closed chamber should be opened to limit heat creep.

Questions

Can the stock A1 or A1 mini nozzle print carbon-fiber filament?

The printer records say no. Both store hardened nozzle as false and a stainless steel nozzle. The A1 mini FAQ says carbon-fiber or glass-fiber filament needs a hardened steel nozzle, sold separately.

Does ordinary TPU go in the AMS lite?

The A1 TPU threads are about loading TPU on the external path, with a short PTFE run and a dry box. Ordinary TPU stays off the AMS hub. The AMS guide and the TPU-on-Bambu guide are the limits, and TPU for AMS is the spool named for that path.
