Pros & Cons
Elegoo Mars 4 Ultra
+9K resolution is a meaningful jump from 7K: finer surface texture, sharper edges on small parts
+Tilt release means FEP films last longer; $50 less per year in consumables is real money
+Built-in air purifier takes the edge off the smell without requiring an external solution
+WiFi monitoring means you can start a print and check it from another room
−153x77mm plate is tight for anything larger than small character models
−Still needs a wash and cure station: budget $50-80 extra
−Resin workflow is messier and slower to start than FDM
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
