Bambu Lab H2S AMS Combo 3D Printer

The Ultimate High-Speed, Multi-Material 3D Printing Solution

Introduction to Bambu Lab H2S AMS Combo

The Bambu Lab H2S AMS Combo is a cutting-edge 3D printer designed to push the boundaries of additive manufacturing. With its massive 340×320×340 mm³ print volume, this machine gives creators the ability to produce large-scale parts, prototypes, and functional components in a single print job. Unlike conventional 3D printers, the H2S delivers industrial-grade precision, achieving motion accuracy under 50 μm, thanks to its 5μm optical motion calibration and Vision Encoder technology. This means users can expect exceptional dimensional accuracy, making it an ideal solution for engineers, designers, and makers who demand professional results. Whether you’re printing single-color models or multi-material assemblies, the H2S AMS Combo offers unparalleled reliability and versatility.

Multi-Color & Multi-Material Printing with AMS 2 Pro

One of the most powerful features of the H2S AMS Combo is its Automatic Material System 2 Pro (AMS 2 Pro), which revolutionizes multi-color and multi-material 3D printing. Supporting up to 24 colors or multiple material types in a single job, AMS 2 Pro enables seamless transitions between filaments with zero manual intervention. The system uses RFID synchronization to automatically detect Bambu’s official filaments, adjusting optimal drying and temperature settings to guarantee perfect quality. You can combine PLA, PETG, ABS, PC, PPA, and engineering-grade filaments effortlessly. For designers, this means creating vibrant, multicolored prototypes, while engineers can manufacture functional components combining flexible and rigid materials—all with a single machine.

Industrial-Grade Motion Accuracy & Optical Calibration

The H2S achieves industry-leading precision by introducing 5μm resolution optical motion calibration paired with the innovative Vision Encoder system. Over time, all 3D printers experience mechanical drift and micro-wear that affect accuracy, but the H2S combats this problem with distance-independent motion correction. During automatic calibration, the printer identifies and compensates for deviations, ensuring consistent performance even after years of use. For applications involving precision-fit parts like gears, shafts, and casings, this feature guarantees perfect dimensional matching without the need for extensive trial and error.

High-Performance Hotend & Heated Chamber

Equipped with a 350°C all-metal hotend and a 65°C actively heated chamber, the Bambu Lab H2S supports a wide range of advanced engineering filaments. Whether you're printing standard materials like PLA and PETG or high-performance filaments like PC, PPA, and ABS, the heated chamber minimizes warping and improves layer adhesion, resulting in stronger, more durable parts. Coupled with closed-loop thermal control, the printer maintains precise temperatures throughout the process, creating industrial-grade results without the need for third-party enclosures.

AI-Powered Print Monitoring and Error Detection

The H2S is equipped with 23 smart sensors and 3 AI-driven cameras that continuously analyze every stage of the print. Its advanced detection system identifies clogs, filament tangles, layer misalignments, spaghetti errors, and purge chute blockages in real time. When a problem is detected, the printer can automatically pause or adjust the settings to prevent failed prints and material wastage. This makes the H2S an extremely reliable choice for complex and long-duration jobs, where errors can be costly and time-consuming.

Superior Surface Quality with Smart Extrusion Control

By integrating a closed-loop servo motor extruder with nozzle pressure sensing technology, the H2S precisely manages extrusion flow at all times. The system dynamically calibrates Pressure Advance (PA) parameters for each filament type, delivering crisp edges, smooth surfaces, and flawless overhangs. This ensures that even at high speeds of up to 1000 mm/s, the printer produces professional-quality surface finishes without artifacts or inconsistencies.

High-Speed Printing Without Compromising Quality

The PMSM servo extrusion system delivers up to 67% more extrusion force compared to traditional stepper motors, supporting high-flow printing and allowing speeds of up to 1000 mm/s and acceleration rates of 20,000 mm/s². Combined with real-time active vibration compensation, the printer neutralizes resonance effects, maintaining smooth layer alignment and sharp details. This results in printing times reduced by up to 30%, making the H2S one of the fastest yet most precise 3D printers in its category.

Optional 10W Laser Cutting & Digital Engraving Module

The H2S isn’t just a 3D printer—it’s a multi-functional fabrication hub. With the optional 10W laser and cutting module, you can engrave, cut, and mark materials like plywood, acrylic, PU leather, vinyl, and paper. The integrated Live Spatial Alignment system uses a top-down BirdsEye camera to project the toolpath directly onto the material surface, achieving 0.3mm positioning accuracy. Combined with Air Assist technology, the module ensures cleaner cuts, minimal soot buildup, and sharper engraving results—all while keeping your workspace safe with an integrated filtration system.

Smart Filament Drying & Storage System

Humidity can significantly affect filament performance, but the H2S solves this with its active filament drying and airtight AMS storage. Filaments are automatically rotated during the drying process for even moisture removal, preserving material integrity. The auto-adjusting drying settings based on RFID data ensure every material is kept in optimal printing condition—especially important for sensitive engineering filaments like PA, PC, and TPU.

Multi-Layered Safety System

Safety is a top priority for the H2S. Equipped with five flame sensors, front-door and top-cover sensors, and an emergency stop button, the printer ensures maximum protection for both users and the workspace. In case of overheating, enclosure misalignment, or unexpected faults, the system can immediately halt operations and trigger protective measures, giving peace of mind even during long unattended print sessions.

Connectivity and Offline Operation

The H2S offers seamless cloud connectivity, enabling users to remotely monitor, control, and manage their prints via desktop, tablet, or smartphone. For security-sensitive environments, the printer also supports fully offline operation, allowing firmware updates and file transfers without requiring an internet connection. Additionally, Developer Mode enables MQTT protocol integration, allowing third-party developers to create custom workflows and automation systems.

Designed for Comfort and Durability

Built with an all-metal die-cast aluminum chassis, the H2S provides a rigid, vibration-free foundation for ultra-high-speed printing. The machine’s quick-swap nozzle system allows tool-free changes within seconds, making material transitions fast and effortless. Its ergonomic design, noise-cancellation features, and below-50dB operation make it ideal for home, office, and professional studio environments.

Ultra-Quiet, Powerful Performance

Unlike traditional high-performance 3D printers, the H2S has been designed for quiet operation. With active motor noise cancellation and specialized air duct soundproofing, the printer maintains noise levels below 50dB, allowing you to print overnight or in shared workspaces without disruptions—perfect for designers, engineers, and makers who value both power and peace.

Maximum Productivity with Large Build Volume

With its 340×320×340 mm³ build area, the H2S unlocks the ability to print large objects in a single run, reducing assembly requirements and improving structural strength. Whether it’s functional prototypes, industrial components, or artistic sculptures, the expansive workspace offers endless creative possibilities and maximum productivity.
