Bambu Lab A1vsPrusa Research CORE One L
💰Bambu Lab A1 is $1400 cheaper (351% less)
📐Prusa Research CORE One L has 77% more build volume
🏠Only Prusa Research CORE One L has an enclosure — required for ABS, ASA, PA engineering filaments
🎨Only Bambu Lab A1 supports multicolor printing (4 slots)
⚠️ 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.
