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
Longer Orange 4K
+$129 is the absolute floor for resin printing
+WiFi at this price is genuinely surprising
+4K resolution is enough to see if resin is your thing
−118x66mm build plate: one mini at a time, if they're small
−4K resolution is dated next to 9K and 12K competitors
−Long-term reliability is unknown; smaller community means fewer fixes documented online
