    "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."
  ],
  "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."
  ],
  "community": "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.",
