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
Elegoo Neptune 4 Max
+420x420x480mm with Klipper for $469: the price-to-volume ratio is hard to beat
+Direct drive on a bed this large is unusual and useful for flexible materials
+Klipper gives you full control to tune speed and acceleration for the mass of this bed
+Prints full armor breastplates in a single run
−Open frame at this scale means ABS warping will ruin prints without serious prep
−The sheer footprint means a dedicated table minimum; don't try to share desk space
−Slower effective speeds on a 420mm heated bed: physics wins eventually
