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
Prusa Core One
+Prusa reliability is not marketing. It's earned over years.
+55C active chamber heating handles demanding materials
+Fully open-source, no vendor lock-in anywhere
+Kit option at $949 saves 21% if you don't mind the build
−$1,199 assembled is hard to justify against the Bambu alternatives
−Build volume is smaller than what you'd expect at this price
−22.5kg is a lot to move around
−No LiDAR, no AI monitoring
