Late in cycle — a new model is likely coming soon
Best for: Makers who want large prints and multicolor capability without an enclosure — ideal for PLA, PETG, and flexible materials.
Full details →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale.

Unlike the A1 Mini's AMS Lite, the A1 Combo includes the full AMS with support for a wider range of filament types.
The largest build volume available in a Bambu bed-slinger — great for terrain, large cosplay props, and functional parts.
Works with Bambu Studio, Bambu Handy app, and the full Bambu filament ecosystem including multi-material profiles.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
