Anycubic Kobra 3 Max vs Anycubic Kobra S1 Max
Technical comparison · Fused filament fabrication (FFF/FDM)
Choose the Anycubic Kobra 3 Max if you need a larger build volume (420x420x500 mm), a native Klipper ecosystem, and management for up to 8 colors. Choose the Anycubic Kobra S1 Max if you prefer CoreXY kinematics, an enclosed chamber, and higher temperatures up to 350°C for the nozzle and 120°C for the bed.

| Software notes | Equipped with Kobra OS, a Klipper-based firmware, controllable via a 4.3-inch touchscreen. Compatible with Anycubic Slicer and third-party software like OrcaSlicer. Features Wi-Fi for remote control via app. Multicolor printing requires the ACE Pro module, sold separately. | 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 and Dimensions: The Kobra 3 Max features a 420x420x500 mm build volume with an external footprint of 70.6x94x75.3 cm. The Kobra S1 Max offers a smaller 350x350x350 mm volume but is more compact (50.27x48.3x58.4 cm).
- Kinematics and Structure: The Kobra 3 Max operates on Cartesian kinematics with an open frame, whereas the Kobra S1 Max utilizes CoreXY kinematics with a fully enclosed chamber.
- Maximum Temperatures: The Kobra S1 Max reaches higher thermal thresholds with a 350°C nozzle and 120°C bed, compared to the 300°C nozzle and 90°C bed of the Kobra 3 Max.
- Multi-color and Firmware: Both support multi-color printing via an optional external module, but the Kobra 3 Max manages up to 8 colors (via ACE Pro) and features native Klipper, while the S1 Max supports up to 4 colors (via ACE 2 Pro) with non-native Klipper firmware.
Which one to choose
Choose Kobra 3 Max if…
The Anycubic Kobra 3 Max is suitable for users who prioritize build volume (420 x 420 x 500 mm compared to 350 x 350 x 350 mm on the S1 Max) and require extended multi-color capabilities up to 8 colors via the separately sold ACE Pro module, while benefiting from native Klipper firmware.
Choose Kobra S1 Max if…
The Anycubic Kobra S1 Max is the ideal choice if you prefer CoreXY kinematics and an enclosed chamber structure. It is designed for processing materials requiring higher temperatures, reaching up to 350°C at the nozzle and 120°C on the heated bed, despite its smaller build volume.
