Bambu Lab H2S (AMS Combo) — Large Format, Multi-Color, Built for Production The H2S AMS Combo combines Bambu Lab’s new large-format platform with automated multi-material printing in a fully enclosed system. With a 340 × 320 × 340 mm build volume, 350 °C hotend, active 65 °C chamber heating, and a closed-loop servo extruder, the H2S is designed for stable, repeatable results on big parts and long jobs. A large touchscreen, bright internal lighting, and automated checks make it easy to run day-to-day—whether you’re prototyping, teaching, or producing parts. Why choose the H2S AMS Combo • Multi-color and multi-material printing out of the box with AMS• Large build volume for helmets, enclosures, fixtures, and production parts• Closed-loop servo extruder for consistent flow and clean surfaces• Actively heated chamber to reduce warping and improve layer adhesion• Enclosed design with airflow control for safer, more predictable printing• Expandable with hubs to add more AMS units and colors Key features • 340 × 320 × 340 mm build volume• All-metal quick-swap hotend up to 350 °C• Active chamber heating up to 65 °C• Closed-loop servo extrusion system• Automatic vibration and flow compensation• AI-assisted filament path monitoring and error detection• Large touchscreen interface with improved lighting and camera monitoring Precision & calibration • Supports Vision Encoder (sold separately) for high-accuracy XY calibration• Helps maintain dimensional accuracy on large or long-running prints• Automatic start-of-print checks and motion compensation AMS details • One AMS included (4 spools per unit)• Automatic filament switching and buffered feeding• Designed to keep filament handling smooth and consistent• Expandable with hubs for additional AMS units What’s in the box • H2S 3D printer• Textured PEI build plate• AMS unit with required cables and spool hardware• Spool holder, accessory kit, safety key, and setup materials Who it’s for • Shops and teams printing large parts with minimal tuning• Schools and makerspaces needing enclosed, multi-material capability• Print farms scaling up to larger formats and higher throughput Policy snapshot 3D printers, AMS units, and filament are final sale.
