Pros & Cons
Elegoo Neptune 4 Max
+420x420x480mm with Klipper for $469: the price-to-volume ratio is hard to beat
+Direct drive on a bed this large is unusual and useful for flexible materials
+Klipper gives you full control to tune speed and acceleration for the mass of this bed
+Prints full armor breastplates in a single run
−Open frame at this scale means ABS warping will ruin prints without serious prep
−The sheer footprint means a dedicated table minimum; don't try to share desk space
−Slower effective speeds on a 420mm heated bed: physics wins eventually
Phrozen Sonic Mini 8K S
+22-micron XY resolution: individual scales on dragon miniatures, every rivet on armor, no blurring
+ParaLED 3.0 delivers even exposure across the full plate, no hot spots
