โš ๏ธ Ecosystem lock-in warning: Bambu and Prusa are not interchangeable ecosystems. Bambu's AMS system is proprietary โ€” multicolor filaments, cloud features, and software are tightly coupled. Prusa's MMU3 is open source. Switching ecosystems later means replacing filament profiles, software presets, and accessories. Choose based on your long-term workflow, not just the current specs.

Why buy each?

Bambu Lab A1 Mini

Plug-and-play setup

The A1 Mini sets up in minutes with automatic calibration and Bambu's guided first-print workflow.

AMS Lite multicolor

Up to 4 colors with the AMS Lite accessory โ€” Bambu's filament switching system with minimal waste purging.

Compact footprint

Fits on a desk or shelf without taking over your workspace, while still printing at 500 mm/s.

Prusa Research Core One

Prusa's answer to Bambu P-series

The Core One matches Bambu CoreXY speed (600 mm/s) while keeping everything open source โ€” firmware, hardware, slicing profiles.

Fully open source

Unlike Bambu's closed ecosystem, every component of the Core One can be modified, repaired, or community-improved.

MMU3 multicolor compatible

Existing MMU3 units and the new MMU3 for Core One bring 5-color multicolor printing to the CoreXY platform.
