Fused filament fabrication (FFF/FDM)
F2 · Intermediate
The Elegoo Neptune 4 Plus is positioned in the intermediate tier due to its generous build volume and the high speeds achievable through native Klipper firmware. It is ideal for experienced hobbyists and prosumers who need to produce large prototypes or moderate batches without investing in industrial machines. It requires basic knowledge of print parameters and the typical maintenance of open Cartesian architectures, making it less self-configuring than fully closed solutions, but offering ample operational flexibility for profile optimization.

Software
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.
Reviews from those who use this machine every day will be available in the next version of the platform.
