| Software notes | The A2L is compatible with Bambu Studio, Bambu Lab's proprietary slicer for Windows and macOS, which provides native access to all machine features including AMS multi-color management. Third-party slicers that export standard G-code — such as PrusaSlicer and OrcaSlicer — are supported, though some advanced features may not be available outside Bambu Studio. Connectivity is via Wi-Fi; basic printing functions do not require a cloud account. | 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. |

- Multicolor printing: A2L yes, Elegoo Neptune 4 Plus no
- Requires external accessory: A2L yes, Elegoo Neptune 4 Plus no
- Max bed temperature: A2L 80 °C vs Elegoo Neptune 4 Plus 110 °C — Elegoo Neptune 4 Plus wins (+38%)
Which one to choose
Choose A2L if…
you value maximum colors 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.»
Choose Elegoo Neptune 4 Plus if…
you value native klipper, max bed temperature and maximum z height. «Klipper is an open-source firmware that offloads trajectory calculations from the microcontroller to a host computer, enabling all advanced features including input shaper and pressure advance. Native support eliminates the need to replace the firmware, a process that voids the warranty on some machines. Relevant for users who intend to tune advanced parameters; for basic use the difference from Marlin is minimal.»
