Pros & Cons

Neptune 4 Max

  • +420x420x480mm with Klipper: the price-to-volume ratio is hard to beat

  • +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

Adventurer 5M Pro

  • +HEPA filter and enclosure at this price is genuinely rare in this class
  • +Nozzle swaps with no tools: pull out, push in, done in 30 seconds
  • +600mm/s means speed doesn't suffer for the enclosure premium
  • −220x220mm build volume is cramped compared to open-frame rivals
  • −Proprietary nozzles mean you can't raid a generic nozzle pack
