Elegoo Centauri Carbon 2 vs Elegoo Neptune 4 Plus

Technical comparison · Fused filament fabrication (FFF/FDM)

In brief

Two Elegoo printers at nearly the same price that bet on different priorities: the Centauri Carbon 2 closes the chamber and preps for multicolor, the Neptune 4 Plus goes for a taller, wider build volume.

Software notes The proprietary Elegoo OS, built on Klipper architecture, manages full-auto calibration routines and AI-assisted monitoring. The machine is primarily supported by Elegoo Slicer (an Orca Slicer derivative), ensuring optimal control over material profiles and dynamic color changes. Users can also natively use Orca Slicer or export G-code from third-party alternatives like Cura. The intuitive touchscreen and Wi-Fi connectivity enable seamless remote management and direct job queuing over the local network. The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer.

The differences that matter

  • Enclosed chamber: present on the Centauri Carbon 2, absent on the Neptune 4 Plus → less draft exposure for ABS/ASA on the former.
  • Z height: 256 mm vs 385 mm → the Neptune 4 Plus prints taller vertical parts.
  • Work area: 256×256 mm vs 320×320 mm → more floor space on the Neptune 4 Plus.
  • Colors: up to 4 with an accessory on the Centauri Carbon 2, single color on the Neptune 4 Plus.

Which one to choose

Choose Centauri Carbon 2 if…

Anyone printing ABS or ASA who wants to cut down on draft-related warping works with the enclosed chamber; adding the color module brings up to 4 colors in the same part. The trade-off is a smaller bed (256×256 mm) and a lower build height (256 mm), so shorter vertical parts.

Choose Neptune 4 Plus if…

Anyone printing tall objects — vases, vertical supports, long molds — gets 385 mm of Z height and a wider bed (320×320 mm) than the Carbon 2. What's given up is the enclosed chamber and multicolor: this one prints a single color in an open frame.
