Pros & Cons
Bambu Lab A1
+Full 256mm build volume, same as the Combo but $100 cheaper
+Bambu's reliability, slicer, and support at $299
+500mm/s speed that's calibrated and ready without tweaking
+AMS Lite upgradeable later when multi-color becomes interesting
−Open frame: ABS warping is a real problem without modification
−No multi-color in the box: the Combo is $100 more and includes it
−The upgrade to A1 Combo is tempting enough that many buyers regret not doing it upfront
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
