| 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 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. |

Which one to choose
Choose A2L if…
you value work area, 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 Neptune 4 Pro if…
you value price, native klipper and max bed temperature. «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.»
