Pros & Cons
Bambu Lab P1S Combo
+Enclosed chamber plus AMS multi-material in one box, no separate AMS purchase
+HEPA filter handles ABS fumes; the enclosure keeps chamber temperature stable
+Up to 16 colors by daisy-chaining 4 AMS units
+Bambu's reliability track record is the best in the consumer market
−$699 is a significant step up from the A1 Combo's $399
−The P1S hardware is being superseded by the P2S; check current pricing before buying
−AMS still wastes filament on color transitions; purge blocks help but don't eliminate it
−Enclosure lid has to come off to reach prints mid-job
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
