Anycubic Kobra 3 Max Combo vs Bambu Lab H2S
Technical comparison · Fused filament fabrication (FFF/FDM)
Two FDM printers of the same class with opposite priorities: the Kobra 3 Max Combo gives a very large open build volume, the H2S an enclosed chamber that handles higher temperatures. The price follows the same logic: about €775 against about €1,200.

| Software notes | Kobra OS (based on Klipper) featuring a 4.3-inch touchscreen interface. Compatible with Anycubic Slicer for color management and Wi-Fi connected for remote monitoring via app. The integrated ACE Pro system automatically handles filament changes and active drying. | The H2S uses Bambu Studio as its primary slicer, with full support for proprietary features including automatic calibration, AI monitoring, and AMS management. It also accepts G-code exported from OrcaSlicer, PrusaSlicer, and Cura, though some advanced functions may not be available with third-party slicers. Laser and cutting functions are managed exclusively through Bambu Suite. Developer Mode is available, exposing MQTT access for custom integrations. |
The differences that matter
- Volume 420×420×500 mm vs 340×320×340 mm → a 40 cm tall part fits only the Kobra.
- Open frame, 90 °C bed, 300 °C nozzle vs enclosed chamber, 120 °C, 350 °C → materials that need heat in the chamber can only be printed on the H2S.
- Klipper-based firmware vs Bambu Studio with MQTT in Developer Mode → different tools for anyone who wants to modify or integrate the machine.
- Price about €775 vs about €1,200 → the difference pays for the enclosure and temperatures, not for volume.
Which one to choose
Choose Kobra 3 Max Combo if…
Large parts, up to 420×420 mm at the base and 500 mm tall, in materials that do not need an enclosure. The ACE Pro module handles filament changes and drying, the Kobra OS firmware is based on Klipper, and the price is about €775. You accept the open frame, the 90 °C bed and the 300 °C nozzle: whatever needs more heat stays out.
Choose H2S if…
Parts within 340×320×340 mm printed in an enclosed chamber, with a bed up to 120 °C and a nozzle up to 350 °C. Bambu Studio provides automatic calibration and AMS management, and Developer Mode opens MQTT access for your own integrations. It costs about €1,200, and a 40 cm tall part does not fit.
