Pros & Cons
Bambu Lab X2D
+Dual nozzle at $649, a third of what the H2D costs
+65C heated chamber handles any engineering material you'll realistically use
+31 sensors and a servo extruder with real-time flow compensation
+$100 more than the P2S for dual nozzles and active chamber heating
+Sub-50dB and 3-stage HEPA: runs quietly in a home office
−Same build volume as the P2S, not the H2D's bigger 325mm
−Dual-extrusion mode shrinks the usable X to around 235.5mm
−Brand new. No long-term reliability data yet.
−Vision Encoder is extra, not in the base price
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
