A1 Combo vs Centauri Carbon 2
Same price, same build volume, four colors in both boxes. The A1 is the easier, quieter, more reliable open-frame machine; the Centauri Carbon 2 is the enclosed CoreXY that can print ABS and carbon-fiber blends. Pick by the filament you will actually use.

Bambu Lab A1 Combo
Elegoo Centauri Carbon 2 Combo
Which one should you buy?
Buy the Bambu Lab A1 Combo if you print mostly PLA, PETG and TPU and want the smoothest first-print experience: full auto calibration, quiet 48 dB operation, a polished app and slicer, and the best owner satisfaction in the category.
Buy the Elegoo Centauri Carbon 2 Combo if you want an enclosed CoreXY at this price to print ABS, ASA, nylon and carbon-fiber filaments, with a 350°C hardened nozzle and 110°C bed — and you are willing to fight a few early-firmware rough edges.

Where each one wins
Why the A1 Combo scores higher
- Satisfaction 92 vs 74 and Reliability 88 vs 78: it simply works out of the box more often.
- Quieter, with the most mature slicer and app in the hobby.
- Quick-swap hotend and the cheapest multicolor path for everyday PLA and PETG.
Why the Centauri Carbon 2 is the engineering-filament pick
- Enclosed CoreXY with a 350°C hardened nozzle and 110°C bed: ABS, ASA, nylon and CF blends are on the menu.
- Twice the acceleration rating and a rigid frame for tall, fast prints.
- Features 90 matches the A1; Value 84 is close behind.

Questions buyers ask
Do both print in four colors out of the box?
Yes. The A1 Combo includes the AMS Lite and the Centauri Carbon 2 Combo includes Elegoo’s Canvas system. Both purge waste on color changes, so plan on some extra filament.
Can the Bambu A1 print ABS?
Not reliably. It has no enclosure and Bambu does not recommend adding one, so warping is likely. Stick to PLA, PETG and TPU on the A1 and choose the enclosed Elegoo for ABS or ASA.
Which is better for a first printer?
The A1 Combo. Automatic calibration, quiet running and a polished app make it the easier machine to live with; owner reviews reflect that in its 92 Satisfaction score.
