Neptune 4 Pro

Elegoo 2023
Fused filament fabrication (FFF/FDM) F2 · Intermediate

The Neptune 4 Pro is positioned in the intermediate tier due to a solid balance of high performance and accessibility. Unlike entry-level models, it offers metal guide rails for increased precision at high speeds and native Klipper firmware, allowing the printer to reach up to 500 mm/s. The standard build volume and direct extrusion system make it ideal for demanding hobbyists and makers looking for reliability and speed, without dealing with the assembly or configuration complexity typical of industrial-grade machines or advanced kits.

Ecosystem

Software

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.
