Software notes Pre-installed Klipper firmware with Creality OS interface. Wi-Fi connectivity and built-in 4.3" touch screen. The machine is driven by Klipper firmware pre-installed on a proprietary 64-bit motherboard, ensuring rapid processing for advanced features like input shaping and pressure advance. The manufacturer provides a customized version of Cura (Elegoo Cura), but the printer is fully compatible with major third-party slicers such as PrusaSlicer and OrcaSlicer. Connectivity includes USB ports and a LAN network port, enabling remote management and direct print file transfers via the Fluidd or Mainsail web interfaces integrated into the system.

The differences that matter

  • Closed chamber: K1 yes, Neptune 4 Pro no
  • Max print speed: K1 600 mm/s vs Neptune 4 Pro 500 mm/s — K1 wins (+20%)
  • Price: K1 329 € vs Neptune 4 Pro 299 € — Neptune 4 Pro wins (+10%)
  • Maximum Z height: K1 250 mm vs Neptune 4 Pro 265 mm — Neptune 4 Pro wins (+6%)
  • Work area: K1 220×220 mm vs Neptune 4 Pro 225×225 mm — Neptune 4 Pro wins (+5%)

Which one to choose

Choose K1 if…

you value closed chamber and max print speed. «A closed chamber reduces thermal gradients around the part being built, limiting warping and cracking caused by rapid cooling in high-shrinkage materials such as ABS, ASA, and PC. It also shields the mechanism from drafts and airborne particles. A closed chamber is effectively necessary for technical materials; for PLA and PETG it is an advantage, not a requirement.»

Choose Neptune 4 Pro if…

you value price, maximum z height and work area. «The Z height determines how tall a part the machine can produce in one print. Vertical objects such as vases, load-bearing structures, or casting patterns require a high Z travel. A lower value does not affect quality but forces the user to split or reorient the model. Z height should be considered alongside the XY surface to assess total usable build volume.»
