Bambu Lab H2S Combo – large-format speed, precision and colors in one

The new H2S is the largest Bambu Lab printer with a build volume of 340 × 320 × 340 mm. The Combo package includes the AMS 2 Pro for multi-color/multi-material printing and intelligent filament drying – ready for large-scale, clean, and reliable printing. 

Why you will love it

• Giant print space 340 × 320 × 340 mm – the largest of all Bambu Lab printers; less model splitting, more finished parts in "one go". 

• Fast and stable – toolhead movement up to 1000 mm/s, acceleration 20 000 mm/s² and up to 30 % faster printing compared to X1C thanks to the servo-extruder and active vibration compensation.

• Ready for engineering materials – hotend 350 °C and actively heated chamber 65 °C for PC, PPA, etc.; clean edges and smooth surfaces even for large parts. 

• Smart print control – AI monitoring (23 sensors + 3 cameras) watches for "spaghetti", clogs, and filament flow, runs pre-flight checks, and saves time and material. 

• Multi-color without compromises – the package includes AMS 2 Pro with RFID, automatic drying (Auto-Rotate Drying), and controlled ventilation, so you switch colors/materials without worrying about moisture. 

• Upgrade-ready – optional 10W 455 nm laser (cutting/engraving), digital cutting, and Live Spatial Alignment with the top camera for precise toolpath placement. 

• Quiet operation and robust frame – active motor noise cancellation, operation under 50 dB and all-metal castings for stability at high speeds. 

Ideal use

Prototyping and small series, functional parts from engineering polymers, large decorations or covers, custom products with multiple colors, and for workplaces where fast, repeatable quality is essential.
