Pros & Cons
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
QIDI X-Plus 3
+60C active chamber heating is the real feature: ABS stops warping, Nylon actually sticks
+Handles PA, PC, and carbon-fiber composites without drama
+CoreXY at 600mm/s inside a heated enclosure is genuinely rare under $600
+280mm build volume is larger than most enclosed competitors at this price
−QIDI's slicer software feels like 2020: functional but not pleasant
−Community is small; problems require more DIY solving than Bambu or Creality
−Some components are proprietary, which makes upgrades harder
