Pros & Cons
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
- −Same build volume as the P2S, not the H2D's bigger 325mm
- −Dual-extrusion mode shrinks the usable X to around 235.5mm
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
- −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

- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
