Pros & Cons
Kingroon KP3S Pro V2
+Linear rails at $159 is genuinely unusual: this feature normally costs $300+
+Direct drive handles TPU without the feeding nightmares of a Bowden setup
+Compact footprint fits on a shelf without dedicating a full desk to it
−200mm cube limits what you can print in one go
−Kingroon's community is small: if something breaks, you're mostly solving it alone
−Firmware is functional but hasn't had meaningful updates in a while
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
