Bambu Lab H2S

Bambu Lab H2S — Large Format, High-Performance Production Printer

The Bambu Lab H2S is a large-format, fully enclosed 3D printer designed for stable, repeatable printing of big parts and long-running jobs. Built on Bambu Lab’s new high-performance platform, the H2S delivers strong thermal control, precise extrusion, and production-focused reliability for demanding applications.

With a 340 × 320 × 340 mm build volume, a high-temperature all-metal hotend, and active chamber heating, the H2S is well suited for large functional parts, enclosures, fixtures, and engineering-grade materials.

Key features

• Large 340 × 320 × 340 mm build volume
• All-metal quick-swap hotend up to 350 °C
• Active chamber heating up to 65 °C for improved layer adhesion
• Closed-loop servo extruder for consistent flow and surface quality
• Fully enclosed design with controlled airflow
• Automatic vibration and flow compensation
• AI-assisted filament path monitoring and error detection
• Large touchscreen interface with internal lighting and camera monitoring

Precision and calibration

• Supports Vision Encoder (sold separately) for high-accuracy XY calibration
• Maintains dimensional accuracy on large or long-duration prints
• Automatic start-of-print checks and motion compensation

AMS compatibility

• Compatible with AMS, AMS 2 Pro, and AMS HT
• Supports multi-color and multi-material printing when AMS is added
• Expandable with hubs for multiple AMS units
• This listing is for the H2S printer only (AMS not included)
