Pros & Cons
Bambu Lab P2S
+Quick-swap nozzle: no tools, no waiting for cool-down, no thread damage from hot-tightening
+1080p AI camera pauses the print when it detects layer failures, not just notifies you
+AMS 2 Pro dries filament while printing so you don't need a separate drybox for standard materials
+5-inch touchscreen is large enough to actually use without squinting at a 2-inch screen
−No LiDAR sensor: that capability is still exclusive to the X-series
−P1S owners have no trade-in path; the upgrade cost is the full $549
−Multi-color purges still waste filament; purge blocks help but don't fix the root issue
−The $799 Combo version gets close enough to the H2D's price that a comparison is warranted
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
