Bambu Lab H2C AMS Combo for multi-material 3D printing with minimal purge wasteThe Bambu Lab H2C AMS Combo is a multi-material 3D printer built to produce complex colour and materi al combinations with less waste, less manual intervention, and more consistent results. Its Vortek hotend change system swaps the entire hotend instead of relying on traditional single-nozzle purging, while AMS integration automates filament handling for advanced print jobs. Key product features Hotend change multi-material printing Minimal purge waste multi-colour printing Precise and fast inductive nozzle heating Close-loop servo extruder Full filament path AI error detection 350°C nozzles and 65°C active heated chamber Optional 10W/40W laser and cutting module 330 × 320 × 325 mm³ build volume How the H2C changes multi-colour and multi-material printingThe H2C is designed for users who want integrated parts instead of painted assemblies or glued components. By combining automated hotend changes, dedicated filament mapping, chamber heating, and AI-based monitoring, the printer supports more ambitious projects while reducing setup friction.Print up to 7 colours in one piecePurge saving multi-colour printingThe H2C brings designs to life with six-colour printing and a versatile seventh nozzle for support or an additional colour. Intricate models that would normally need painting can be produced directly from the printer, and the example shown was printed in 2 parts, with the main raptor in 6 colours and the base in another 6-colour setup.Print multi-material parts in one piece instead of assembling them laterPurge saving multi-material printingThe H2C can print up to seven different materials in a single run with no nozzle purging required during normal material swaps. Combining multiple material properties in one seamless structure makes it possible to create integrated designs that would otherwise require post-assembly.Build flexible joints directly into printed partsIntegrated TPU joints for multi-colour partsThe H2C can print durable TPU ball joints directly into robot models and other moving assemblies. Flexible joints built into the part help create long-lasting mechanisms designed for repeated motion.Vortek hotend change system for lower waste and automatic material handlingMulti-material printing with minimal purge wasteTraditional single-nozzle multi-material printing requires purging leftover material between filament changes. The Vortek system replaces the entire hotend instead, producing faster and cleaner transitions with minimal waste.Fully automatic filament changeThe Vortek system works with the Bambu Lab AMS to automate the full filament change process. Filaments do not need to be manually loaded into the toolhead for each swap, which simplifies long and complex print jobs. Optimised hotend and filament allocationThe Vortek system stores filament information in each hotend’s memory so the correct filament can be matched to the correct hotend. When a job uses more than seven filament types, the system calculates an efficient combination to minimise purge waste. Why the Vortek system mattersMore filaments in a compact formatBecause the H2C swaps only the hotend, the printer can house up to six replaceable hotends without significantly reducing build volume. That design supports more colours, more materials, and more flexibility in a comparatively compact toolhead system.8-second induction heatingInduction heating brings the nozzle to temperature in 8 seconds, significantly reducing preheating time during material changes compared with traditional approaches. Faster reheating helps keep multi-material workflows practical on longer jobs. Contactless design for stable connectionsThe H2C avoids contact-based metal pins that are vulnerable to oxidation and unstable electrical connections. Its contactless solution maintains a stable high-frequency connection that supports precise temperature control and intelligent hotend synchronisation.Support for up to 24 materials in a single printColour count is not limited by the number of toolheads alone. With parallel-connected AMS units, the H2C supports up to 24 materials in a single print, and its control algorithm optimises filament-to-hotend allocation to minimise purge waste while maintaining strong multi-colour and multi-material performance.Enclosed design for engineering materialsThe seamless enclosure and adaptive airflow system help maintain a stable chamber temperature for high-performance materials. The enclosed structure also filters air to help keep the workspace cleaner when printing demanding filaments.Automatic nozzle offset calibrationThe H2C performs inductive nozzle offset calibration automatically, without manual steps, calibration plates, or additional setup. In a few minutes, the system calibrates nozzle offset to within 25 microns. Dedicated hotends for specific filamentsOne of the six interchangeable hotends can be reserved for a specific filament, which is especially useful for valuable engineering materials. Each hotend can store filament information so that the next time the material is loaded, it can be matched automatically to the correct hotend.Top-tier printing performance for demanding partsHigher extrusion force and real-time fault detectionThe PMSM servo extruder delivers up to 10 kg of maximum extrusion force, which is 70% more than a stepper motor. Bambu Lab’s servo architecture samples resistance and position at 20 kHz to actively detect filament grinding and clogs in real time, improving stability during high-flowrate extrusion. 50 μm ultra-fine motion accuracyWith its Vision Encoder, the H2C achieves distance-independent motion accuracy of less than 50 μm, which is thinner than human hair. The system automatically compensates for mechanical drift during calibration to maintain precision over time. Smoother surfaces and sharper edgesThe H2C uses the extruder servo motor together with high-resolution eddy current sensors on the nozzle to sense extrusion dynamics. That data enables precise extrusion control and automatic calibration of Pressure Advance parameters for each filament, improving surface finish and edge definition.Built for high-performance, high-temperature filamentsThe 65°C actively heated chamber and 350°C nozzles reduce warping and deformation while improving layer adhesion with high-performance materials. This setup is intended for users who need stronger functional parts and more reliable results with engineering-grade filaments. Comprehensive print monitoringThe H2C is equipped with an array of 59 sensors and a quad-camera computer vision system managed by a proprietary neural algorithm. During printing, the system delivers intelligent real-time diagnostics that can detect subtle print anomalies as they happen.AI camera for safer print starts and live fault detectionThe AI-backed camera system continuously monitors extrusion patterns and detects material accumulation, filament deviations, and extrusion failures. It also performs a pre-flight scan to help verify a safe start before printing begins. Safety and operating environmentThree-stage air filtration for engineering filamentsThe H2C uses a three-stage filtration system consisting of a G3 pre-filter, an H12 HEPA filter, and a coconut shell activated carbon filter. This filtration setup helps minimise odours and harmful particulates often released by engineering materials.Flame-retardant chamber constructionThe printer chamber is constructed entirely from flame-retardant material to provide passive fire safety protection throughout the enclosure. The fire-retardant chamber uses UL94 V-0 grade materials.Flexible network security and connectivity optionsThe H2C supports cloud connectivity for remote control from any device and also supports full offline operation for physically isolated environments. Files can be sent, the printer can be operated, and firmware can be updated without an internet connection, while Developer Mode provides MQTT port access for advanced third-party integrations.Use cases for the Bambu Lab H2C AMS ComboMulti-colour display models and figuresThe Vortek system and AMS workflow suit users who want to print detailed figures, props, and decorative parts with multiple colours directly from the machine instead of relying on manual painting.Functional prototypes with mixed material propertiesPrinting rigid and flexible sections in one job makes the H2C suitable for mechanical prototypes, integrated clips, living assemblies, and robot parts with built-in TPU joints.Engineering parts that need chamber heat and high nozzle temperaturesThe heated chamber, 350°C nozzle capability, enclosed frame, and filtration system make the printer appropriate for high-performance materials where warping control, adhesion, and air handling matter.Secure or advanced workflowsOffline operation supports organisations that need physical network isolation, while MQTT access in Developer Mode supports users integrating the printer into custom monitoring or automation systems.Unboxing video Important notesAll demonstrated print time and purge waste data are calculated results by Bambu Studio.The advertised Vortek features and advantages are based on fully utilising 6 induction hotends of the same diameter and corresponding AMS units.All product data for the H2C is based on Bambu Lab internal testing.
