⚠️ Ecosystem lock-in warning: Bambu and Prusa are not interchangeable ecosystems. Bambu's AMS system is proprietary — 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.
