Pros & Cons
Bambu Lab A1 Combo
+AMS Lite ships in the box, not as a $75 upsell
+Bambu Studio slices and sends in under a minute
+500mm/s speed that actually holds up at 0.2mm layers
+Auto bed leveling runs in 90 seconds, not 10 minutes
−Open frame means ABS is borderline without an enclosure
−AMS Lite tops out at 4 colors; want more, buy a different system
−You're locked into Bambu Studio for the best experience
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
