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 Mars 4
