Bambu Lab H2S – large format, single nozzle, maximum reliability

H2S is the largest "single-nozzle" printer from Bambu Lab: it handles technical materials, rapid prototyping, and small series – all with precision that keeps pace even after thousands of hours of operation. A build volume of 340 × 320 × 340 mm allows you to make parts "in one go" instead of assembling them from multiple pieces.

Why choose H2S

• Giant build space 340 × 320 × 340 mm – the largest in the entire Bambu Lab range. Less gluing, more finished pieces.

• Fast pace without compromises – up to 1000 mm/s tool speed and 20 000 mm/s² acceleration; new DynaSense servo-extrusion with up to 10 kg of extrusion force for stable high-flow printing.

• Constant precision – with the optional Vision Encoder, it achieves movement precision of < 50 μm and automatically compensates for mechanical deviations over time.

• Technical materials without stress – 350 °C hotend and 65 °C actively heated chamber for PC, PA, PPA-GF/CF, etc.; controlled airflow minimizes warping and improves layer adhesion.

• AI supervision & error prevention – 23 sensors and 3 cameras monitor filament flow, clogs, "spaghetti" and perform pre-flight check of surface and configuration.

• Quiet and robust – active motor noise cancellation, die-cast construction and quiet operation < 50 dB.

• CoreXY platform – rigid mechanics for high speeds and clean edges.

Key parameters (selection)

• Build volume: 340 × 320 × 340 mm.

• Speed / acceleration: up to 1000 mm/s / 20 000 mm/s²; up to ~30 % shorter times vs. X1C (according to internal BL tests).

• Extrusion: PMSM DynaSense (20 kHz sampling), up to 10 kg force; active vibration compensation.

• Temperatures: hotend 350 °C, chamber 65 °C (active).

• Motion precision: < 50 μm with Vision Encoder (optional).

• Supervision and safety: 23 sensors, 3 cameras, 5 flame detectors, door/lid sensors, Emergency Stop.

• Supported materials: PLA, PETG, TPU, ABS/ASA, PC, PA, PPA-GF/CF, PPS-GF/CF and others.

• Connectivity and modes: cloud and fully offline operation; Developer Mode with access via MQTT.

Compatibility and expansions

• Multi-color / multi-material: compatible with AMS 2 Pro, AMS and AMS HT (optional accessories). Intelligent drying and RFID pairing with AMS 2 Pro.

• Manufacturing hub on your desk: possibility to add 10W 455 nm laser, digital cutting and drawing; precise tool positioning thanks to Live Spatial Alignment (top BirdsEye camera is included in the Laser Edition or Laser Upgrade kit).

Ideal use

Large-format prototypes, functional parts from technical polymers, small series production, precision components with holes for bearings/screws (Auto Hole/Contour Compensation), design pieces and custom manufacturing with multi-color capability via AMS.
