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 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
