| Software notes | 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 primary software is Snapmaker Orca, an optimized version of the popular OrcaSlicer, which provides native management of the four toolheads and factory-calibrated material profiles. The printer can also be seamlessly managed via the Snapmaker mobile app for remote monitoring, taking advantage of the built-in 1080p camera. The internal firmware is built on Klipper, Moonraker, and Fluidd, which Snapmaker has made open-source, allowing experienced users to customize the machine and integrate it into complex workflows. |

Which one to choose
Choose Elegoo Neptune 4 Plus if…
you value price, maximum z height and work area. «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.»
Choose U1 3D Printer if…
you value maximum colors, multi-extruder 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.»
