Pros & Cons
Elegoo Centauri Carbon
+Enclosed CoreXY at $299. Yes, really.
+PLA, PETG, ABS: all print well out of the box
+Pre-assembled, printing within minutes of opening the box
+Carbon-fiber-infused materials are a go
−Firmware needs attention after unboxing
−Heat creep shows up on long prints above 270C
−Elegoo's ecosystem is years behind Bambu's
−17.5kg for a 256mm build volume is heavy
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
