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
−Lidar calibration adds setup time on every new filament type
−AMS still purges filament on color transitions; purge blocks reduce waste but don't eliminate it
−Bambu ecosystem lock-in: proprietary slicing workflow works best with Bambu Studio
Phrozen Sonic Mega 8K S2
+330x185mm plate is the largest resin build area in the consumer market at this price
+8K detail across the full plate without the hot spot degradation that plagues cheaper large-format LCDs
+Dual tilt release on a plate this size prevents the vacuum seal failures that ruin large prints
+Professional-grade aluminum build quality that handles the stress of frequent full-plate runs
−$749 for a resin printer is a serious investment, plus $80-120 for a wash station to match
−High resin consumption: a full plate run uses 400-500ml, which adds up weekly
−100mm/hr speed is the same as entry-level machines: the size advantage doesn't come with a speed advantage
