Pros & Cons
Bambu Lab P1S
+HEPA filter actually handles ABS fumes, not just PLA smell
+CoreXY at 500mm/s inside an enclosed chamber
+Reliability track record is as good as anything at this price
+AMS multi-material works without the constant jams you get on cheaper systems
−$449 without AMS, which adds another $100-150 on top
−Enclosure lid has to come off to reach prints mid-job
−P1P owners considering an upgrade: this is it, but it stings
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
