Anycubic Kobra 3 vs Anycubic Kobra S1 Max
Technical comparison · Fused filament fabrication (FFF/FDM)
Same brand, two different setups: the Kobra 3 is an open-frame printer for a single color, the Kobra S1 Max an enclosed CoreXY at 350 mm a side, multicolor too. Volume and price decide: the S1 Max costs about €440 more.

| 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 firmware runs on a proprietary Kobra OS layer built on top of Klipper; the official slicer is Anycubic Slicer Next, derived from OrcaSlicer, available for Windows and macOS. Third-party OrcaSlicer is also supported. Remote monitoring and control are available via the Anycubic app (iOS/Android) over LAN, with no mandatory cloud connection required for ordinary printing operations. Unlike the Combo version, the ACE 2 Pro module is not included in the box. |
The differences that matter
- Build volume: 250 × 250 × 260 mm against 350 × 350 × 350 mm → on the Kobra 3 a large part has to be split and glued.
- Chamber and temperatures: open, 300 °C and 110 °C against enclosed, 350 °C and 120 °C → filaments that want more heat stay with the S1 Max.
- Colors: one only against up to 4 with an accessory → on the Kobra 3 every object is a single color.
- Firmware: native Klipper against a proprietary layer on a Klipper base → the Kobra 3 leaves more room to configure.
Which one to choose
Choose Kobra 3 if…
You print prototypes and working parts in a single color, within 250 × 250 × 260 mm, and want to stay around €260. It has native Klipper, so the firmware can be configured by hand. The trade-off: open frame, nozzle up to 300 °C and bed up to 110 °C, a single color and a volume that forces you to split large parts.
Choose Kobra S1 Max if…
You print whole parts up to 350 mm, with an enclosed chamber, a nozzle up to 350 °C and a 120 °C bed, and you want multicolor up to 4 colors with the ACE 2 Pro module, which is not in the box. The trade-off: about €440 more and firmware that is a proprietary Kobra OS layer built on Klipper, not native Klipper.
