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-Max 3
+325mm enclosed with 60C active heating is a combination you almost can't find under $1,500
+Independent Z motors keep the bed trammed even on 24-hour prints
+Handles PA-CF and PC natively without a fight
+600mm/s in a large-format heated chamber is rare at any price
−25kg: set it up once and it lives there
−$799 with a smaller community than Bambu means you're mostly on your own troubleshooting
−QIDI's slicer profiles are thin for specialty materials
