| Software notes | Compatible with Bambu Studio (OrcaSlicer-derived) and OrcaSlicer. Supports LAN mode for cloud-free printing. Does not run native Klipper. | 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. |
The differences that matter
- Colors: up to 4 with an accessory on the A1 mini, vs 1 on the Neptune 4 Pro.
- Build plate: 180×180×180 mm (A1 mini) vs 225×225×265 mm (Neptune 4 Pro).
- Bed temperature: 80°C (A1 mini) vs 110°C (Neptune 4 Pro) → more headroom for PETG on the Neptune 4 Pro.
- Native Klipper: only on the Neptune 4 Pro.
Which one to choose
Choose A1 mini if…
Suited to printing small multicolor objects (up to 4 shades with the dedicated accessory) on a desk with limited space (footprint 34.7×31.5×36.5 cm). You accept a smaller build plate (180×180×180 mm) heating up to just 80°C.
Choose Neptune 4 Pro if…
Suited to printing larger parts in one pass (225×225×265 mm build volume) and wanting native Klipper with a Fluidd/Mainsail interface. You give up multicolor printing, and the footprint grows to 47.5×44.5×51.5 cm.
