Pros & Cons
Elegoo Saturn 3 Ultra
+218x123mm plate holds a full 10-model squad in one run at 12K resolution
+Tilt release on a plate this size dramatically reduces FEP tears
+Terrain, dungeon tiles, and large busts all fit without splitting
+150mm/hr speed is faster than most competitors at this plate size
−A full plate run goes through resin fast: budget for 500ml+ per session
−Post-processing for a full plate takes the better part of an hour
−At $299, you're also spending $80-120 on a wash and cure station before you can print anything
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
