Pros & Cons
Bambu Lab X1 Carbon Combo
+Lidar + auto-calibration eliminates first-layer anxiety on high-value prints
+AMS in the box: no separate multi-material module purchase needed
+HEPA filtration makes ABS/ASA printing genuinely office-safe
+Expandable to 16 colors by daisy-chaining up to 4 AMS units
+Bambu's reliability track record is the strongest in the consumer market
−$1,199 is a premium ask; the P1S Combo at $699 covers 90% of use cases for less

−Post-processing adds 30-45 minutes after every print: wash, cure, support removal
