Software notes The A1 works natively with Bambu Studio, Bambu Lab's proprietary slicer available for Windows and macOS, which handles slicing, automatic calibrations, and remote monitoring via the Bambu Handy app. Third-party slicers — including PrusaSlicer, SuperSlicer, and Ultimaker Cura — are supported via standard G-code export, but advanced features such as vibration compensation and active flow control are only available within the Bambu ecosystem. The system relies on an open ecosystem thanks to the motherboard with pre-installed Klipper. Users can manage the machine both through the 4.3-inch capacitive touchscreen interface and via local network using the integrated web interface (Fluidd). Elegoo provides its own customized version of the Cura slicer, but the printer remains fully compatible with most third-party slicers such as PrusaSlicer, OrcaSlicer, and Simplify3D. Native support for Wi-Fi and LAN connectivity facilitates sending and monitoring G-code files without the need for physical media.

  • Maximum colors: A1 4 vs Neptune 4 Max 1 — A1 wins (+300%)
  • Price: A1 429 € vs Neptune 4 Max 549 € — A1 wins (+28%)
  • Native Klipper: Neptune 4 Max yes, A1 no

Which one to choose

Choose A1 if…

you value maximum colors, price and multicolor printing. «The maximum number of colors indicates how many distinct color zones or materials can be used in one print without manual intervention. Two colors cover most practical uses, including soluble support. Higher values are useful for complex decorative models or color-coded prototypes. Each additional color increases print time due to transition purges, so the practical benefit should be weighed against the added time cost.»

Choose Neptune 4 Max if…

you value work area, maximum z height and native klipper. «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.»
