• 340*320*340 mm³ Print Volume
• Multi-color 3D Printing
• Closed-loop Servo Motor Extruder
• Optional 10W Laser and Cutting Module
• 5μm Resolution Optical Motion Calibration
• 350°C Nozzle & 65°C Active Chamber Heating
• Full Filament Path AI Detection
• Voltage Range: 100-120 V

Accuracy That Works for You

Correct Mechanical Deviations - Even though the printer comes out of the factory with superb accuracy, mechanical wear and variances over time are inevitable—but now, for the first time in the industry, there’s a solution. With the Vision Encoder⁽¹⁾, the H2S achieves distance-independent motion accuracy under 50 μm—thinner than a human hair. During calibration, it automatically compensates for mechanical drift, ensuring consistent precision and peak performance over time.

One Print. Perfect Fit.

Bambu Lab's Auto Hole/Contour Compensation⁽²⁾ minimizes printing tolerances, delivering machine-shop-level precision for hole dimensions. Design fit-critical parts with confidence—integrate shafts, bearings, and fasteners without trial and error. Post-print assembly has never been easier.

Ready For Engineering Filaments

Featuring a 350 °C hotend and a 65 °C actively heated chamber, it supports the entire Bambu filament lineup—from PLA and PETG to PC and PPA. With closed-loop fan control and precise thermal management, the H2S minimizes warping and deformation while improving layer adhesion. Build large, high-performance parts that are as functional as they are strong.

Even Surfaces, Crisp Edges

H2S uses both the sensing capability of its servo motor on the extruder and the high-resolution eddy current sensors on the nozzle to precisely control extrusion by measuring nozzle pressure and calibrating PA parameters for each filament, improving surface smoothness and edge sharpness.

Precision in Motion

Active Vibration Compensation neutralizes micro-vibrations and resonance in real time, enabling premium print quality at higher speeds.

Intelligence That's Got Your Back

20,000 Checks Per Second, Closed-Loop Feedback, Real-Time Control

Pre-Flight Checklist by AI

Prior to each operational cycle, the H2S vision system initiates a comprehensive pre-flight checklist: Chamber Integrity Scan – Detects debris across the entire print surface. Hardware Configuration Audit – Instantly identifies build plate properties.

Flap Switch Airflow & Filtration System - 3D Printing & Laser Cutting. 3 Modes, All-in-One

High Temp Printing: Chamber sealed. Internal air recirculates through the Air Filter and the heater to stabilize high-temp conditions. Print large engineering parts without warping.

Low-Temp Printing: Top Vent opens to bring in cool air, while maintaining a filtered exhaust⁽⁴⁾. Print PLA and PETG without opening the door, and handle overhangs and bridging with ease.

Laser Cutting/Engraving: Top Vent and Filter Switch Flap open. Fumes are channeled efficiently to the ventilation system, keeping your workspace safe and clean.

Maximum Volume. Maximum Productivity.

With a build volume of 340×320×340 mm³, the H2S offers the largest print space among all Bambu Lab printers. Your Vision. Fully Realized in One Print. 120% Larger Build Volume than the X1 Carbon.

Top Speed. More Reliable Than Ever with the DynaSense Extruder - Intelligent Sensing for Precise Extrusion Control

Bambu Lab’s proprietary PMSM⁽⁵⁾ servo extrusion system delivers 67% more extrusion force, providing solid support to high flow⁽⁶⁾ printing. Paired with up to 1000 mm/s toolhead speed and up to 20,000 mm/s² acceleration, your H2S can finally go full throttle—cutting your printing time by up to 30%⁽⁷⁾—while maintaining top-tier quality.

Cut. Engrave. Draw. - Compact, Capable, All-in-One.

Live Spatial Alignment. Top-down BirdsEye camera⁽⁸⁾ and onboard toolhead camera enable Live Spatial Alignment, letting you preview the toolpath directly on your material with 0.3 mm accuracy. What you see is what you get.

Auto Arrangement. Bambu Suite automatically arranges your project shapes to make the most of every sheet—smart, efficient, and effortless.

10W 455nm Laser Power. Slice through up to 5 mm plywood, acrylic, or PU with ease—clean, fast, and precise.

Air Assist. Air Assist keeps your lines crisp by blowing away smoke and char while cooling the surface—preventing soot buildup and beam distortion for sharp, clean results.

Digital Cutting. Effortlessly cut through paper, vinyl, PU leatherette, and more—clean, accurate, and ready to apply.

Drawing. Use the drawing module to automate linework, sketches, or handwritten notes—precise, repeatable, and hands-free.

Protected Inside and Out. Safety, Built In.

• Laser Safety Window - Shields your eyes from the 455 nm laser beam while keeping your workspace clear and visible.
• Five Flame Sensors - Advanced sensors continuously monitor for fire risks. If an issue is detected, a loud buzzer and mobile alert⁹ notify you immediately—so you can act fast and stay safe.
• Flame-Retardant Chamber - Constructed with fire-resistant materials throughout, the chamber provides passive protection for added safety.
• Emergency Stop - Immediately halt operations if something feels off—giving you full control and added peace of mind.

Connectivity, By All Means. Privacy, By Design.

The H2S offers seamless cloud connectivity for convenient remote control from any device. For security-sensitive applications, it also delivers complete offline functionality, ensuring physically isolated operation. Users can control the printer, send files, and upgrade firmware—no internet required. Additionally, Developer Mode unlocks MQTT port access, empowering developers and integrators to connect third-party components and custom software with ease.⁽¹⁰⁾

Accessible. Comfortable. Made to Last.

Quick-Swap Nozzle. Swap nozzles in seconds—no tools, no hassle. Whether you're switching materials or upgrading to a different nozzle size, the redesigned hotend makes it easy and intuitive, even for first-time users.

Quiet by Design. With Active Motor Noise Canceling and specialized air duct noise-reduction technology, the H2S operates below 50 dB⁽¹¹⁾. Print overnight or in shared spaces without disrupting your environment.

All-Metal, Die-Cast Body. The integrated die-cast aluminum alloy chassis delivers a sturdy, stable structure that provides a rigid foundation for high-speed, large-format printing, while minimizing accuracy loss caused by micro-twisting.
