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.
A large enclosed build volume with genuine active chamber heating — making the CORE One L reliable for ABS, ASA, PA, and PC across the full build plate.
All firmware, hardware designs, and slicing profiles are open source. Prusa backs the CORE One L with long-term parts availability and community support.
For institutional, government, and production customers, a dedicated Critical Infrastructure Edition is offered — Prusa's commitment to secure supply for professional users.
