Pros & Cons
Elegoo Saturn 4 Ultra
+218x123mm plate fits a full Warhammer squad in one run, not two
+12K resolution holds up just as well as the Mars at 14K for most print sizes
+Tilt release is worth it at this plate size: peel forces on large prints are brutal without it
+Terrain and base tiles look genuinely stunning at this resolution
−Resin consumption goes up fast when you're filling a plate this size
−Post-processing for a full plate run takes 45-60 minutes minimum
−The purifier helps but a plate this big curing kicks up more fumes
Prusa XL
+5 independent tool heads means true material switching, not color blending on a single hotend
+360mm cube handles parts that can't be split and glued
+Segmented heated bed powers down unused zones, saving real electricity on large prints
+Open source: the XL will be hackable in 10 years
−$1,999 and you still print at 200mm/s: the speed is hard to accept at this price
−Delivery times have been 2-4 months; plan accordingly
−The footprint requires dedicated space and a reinforced surface
