Bambu Lab P2S vs Elegoo Neptune 4 Max

Technical comparison · Fused filament fabrication (FFF/FDM)

In brief

The two machines suit different jobs: the P2S is enclosed and prints in several colors, the Neptune 4 Max has no enclosed chamber and prints in a single color, but with a much larger volume. They cost almost the same, €519 and €549: the type of part decides.

Software notes The official slicer is Bambu Studio, available for macOS, Windows, and Linux. The printer also accepts standard G-code exported from third-party slicers such as PrusaSlicer, SuperSlicer, and Cura, though certain advanced Bambu-specific features — including RFID-based filament detection and some automatic calibration modes — are only available within Bambu Studio. Remote control is handled via the Bambu Handy mobile app and desktop app; push notifications require cloud connectivity. 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.

The differences that matter

  • Build volume → 420×420×480 mm against 256×256×256 mm: large parts can only be printed on the Neptune 4 Max (manufacturer's declared values).
  • Chamber → enclosed on the P2S only.
  • Colors → P2S multicolor up to 20 with the accessory; the Neptune 4 Max is single-color.
  • Firmware → native Klipper with Fluidd on the Neptune 4 Max; Bambu Studio on the P2S.

Which one to choose

Choose P2S if…

you print in several colors, up to 20 with the accessory, and want an enclosed chamber. The trade-off is volume, 256 mm a side, and firmware without native Klipper. It costs €30 less.

See the P2S sheet →

Choose Neptune 4 Max if…

you print large parts in a single color and want Klipper with the Fluidd web interface. The trade-off: no multicolor, no enclosed chamber and a 65.8 × 63.2 cm footprint.
