Anycubic Kobra 3 vs Elegoo Neptune 4 Max
Technical comparison · Fused filament fabrication (FFF/FDM)
Same process, very different prices: the Kobra 3 costs about €290 less than the Neptune 4 Max. What decides it is the volume, 250 × 250 × 260 mm against 420 × 420 × 480 mm.

| Software notes | Operated via AnycubicSlicer and compatible with the proprietary cloud app. It leverages a Klipper-based firmware, natively integrating Input Shaping algorithms to reduce vibrations at high speeds. | The system relies on an open ecosystem thanks to the motherboard with pre-installed Klipper. Users can manage the machine both through the 4.3-inch capacitive touchscreen interface and via local network using the integrated web interface (Fluidd). Elegoo provides its own customized version of the Cura slicer, but the printer remains fully compatible with most third-party slicers such as PrusaSlicer, OrcaSlicer, and Simplify3D. Native support for Wi-Fi and LAN connectivity facilitates sending and monitoring G-code files without the need for physical media. |
The differences that matter
- €260 against €549 → about €290 less for the Kobra 3.
- Volume 250 × 250 × 260 mm against 420 × 420 × 480 mm → a 30 cm part fits only on the Neptune 4 Max.
- Bed up to 110 °C against 85 °C (values declared by the manufacturer) → the Kobra 3 bed goes higher, the Neptune 4 Max has less margin.
- AnycubicSlicer and proprietary app against Fluidd over the network and Elegoo's Cura → two different ways of following a print; both run Klipper.
Which one to choose
Choose Kobra 3 if…
you print spare parts, brackets and desktop pieces that fit in 25 cm, and want Klipper with input shaping for about €260. You are limited to 250 mm across and 260 mm in height, with no enclosed chamber.
Choose Neptune 4 Max if…
you print one large piece, such as a shell or a mask, or fill the bed with many objects per batch. You get Klipper and the Fluidd interface on the local network. The trade-off is almost double the price, a bed that tops out at 85 °C and a footprint of 66 × 63 × 74 cm.
