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.

Best for: Professional makers, small studios, and engineers who need dual-material printing — particularly for PVA soluble supports, dual-color engineering parts, or high-throughput production.

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.
The H2S adds better high-speed cooling and more consistent layer adhesion at 600 mm/s, addressing key H2D pain points.
Dual-nozzle printing eliminates the purge tower required by filament-switching systems — faster prints, less wasted filament.
Print PLA + PVA or ABS + HIPS combinations for complex geometries that would be impossible with a single material.
