Pros & Cons
Elegoo Centauri Carbon 2 Combo
+First enclosed multi-color CoreXY under $500
+91% first-attempt success rate on multi-color jobs
+RFID reads filament type automatically, no manual input
+TPU prints without complaints
−Spool holders are finicky
−Loading routine doesn't get hot enough for high-temp filaments
−Build plate grip is mediocre
−Canvas software works but looks like it was designed fast
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
