The Bambu Lab H2S is a large-format enclosed 3D printer with a 340×320×340 mm build volume, the biggest of any Bambu Lab machine. It pairs a 350 °C all-metal hotend and a 65 °C actively heated chamber with a closed-loop servo extruder that samples at 20 kHz and detects clogs and grinding in real time. The AMS 2 Pro adds multi-color and multi-material printing, and an optional 10W laser module, vinyl cutter and pen drawing turn it into a small workshop tool. It suits makers and small shops printing engineering filaments like ABS-GF who want more room than an X1 or P1 series offers, at the cost of a heavier, slower-to-heat machine.

Rated 4.8 out of 5 across 103 ratings, the H2S is well received. Owners value the large build volume and the heated chamber for engineering filaments, and the clog detection gets credit for saving failed prints.
The Bambu Lab H2S is a 3D printer with a 340×320×340 mm³ build volume, the largest of any Bambu Lab printer. It prints in multiple colors with the AMS 2 Pro automatic material system. It can also be expanded with an optional 10W laser cutting and engraving module, a vinyl cutter attachment and pen drawing.
The hotend reaches 350°C and the chamber is actively heated to 65°C. This supports filaments from PLA and PETG to PC and PPA. Closed-loop fan control and thermal management help limit warping and improve layer adhesion. A flap switch airflow and filtration system has three modes: high-temp printing with a sealed chamber, low-temp printing with a filtered exhaust, and laser cutting or engraving with fumes channeled to the ventilation system.
The extruder uses a closed-loop PMSM servo system with 20 kHz resistance and position sampling. It detects grinding and clogs in real time and delivers 67% more extrusion force. The Vision Encoder keeps motion accuracy under 50 μm by automatically compensating for mechanical drift during calibration. Active Vibration Compensation reduces vibration and resonance at higher speeds. Before each print, an AI pre-flight checklist scans the chamber for debris and identifies the build plate.
