Bambu Lab AMS HT

A New Standard in Professional Filament Management

The Bambu Lab AMS HT redefines the boundaries of high-performance filament drying and multi-material management, delivering a fully engineered solution for professional makers, engineering teams, and industrial additive manufacturing environments. Designed to operate at drying temperatures up to 85°C, the AMS HT is purpose-built for engineering-grade materials such as PC, PA, ABS, ASA, PET, nylon composites, and Bambu’s specialized CF filament series. Its airtight architecture, intelligent humidity-controlled feedback loop, and electro-magnetic venting system work in harmony to maintain optimal environmental conditions for even the most moisture-sensitive polymers. Combined with its compatibility with Bambu's RFID ecosystem, brushless servo feeding motor, and scalable multi-unit system supporting up to 24 filaments, the AMS HT ensures continuous, reliable filament flow and superior print consistency.

High-Temperature Drying Up to 85°C for Engineering-Grade Materials

One of the most critical differentiators of the AMS HT is its 85°C maximum drying temperature, which specifically targets high-performance thermoplastics requiring deep moisture extraction. Materials such as PA, PAHT-CF, PETG-CF, PC, and advanced carbon-fiber or glass-fiber composites absorb moisture rapidly and degrade dramatically when printed while wet. The AMS HT uses an advanced controlled heating chamber with precision temperature feedback sensors to eliminate moisture trapped inside filament pores. By maintaining uniform heat distribution and actively rotating spools during drying, the system guarantees even conditioning, improved layer adhesion, and reduced stringing, bubbling, and brittleness.

Electro-Magnetic Air Vent System for Intelligent Moisture Exhaust

At the core of the AMS HT’s drying performance is its electro-magnetic air vent, an intelligent, automated mechanism that switches seamlessly between moisture exhaust mode and airtight storage mode. During drying cycles, the vent opens to release accumulated humid air and accelerate dehumidification. Once drying is completed, the vent seals shut, creating a long-lasting airtight barrier capable of preserving filament quality for weeks. This dual-function design offers a major advantage over traditional manual or passive drying systems, ensuring constant environmental optimization without user intervention.

Rotational Drying System for Even Moisture Reduction

The AMS HT introduces auto-rotate drying, a system where filament spools gently rotate throughout the heating process. This prevents heat stratification and ensures that every layer of filament receives uniform exposure to the drying environment. Wet spots and uneven conditioning—common issues in static dryers—are eliminated. This is particularly advantageous for dense, composite-rich or hydrophilic filaments, enabling consistent extrusion behavior from start to finish.

Air-Tight Filament Storage for Extended Preservation

Beyond active drying, the AMS HT acts as a sealed, climate-controlled storage chamber. Its high-integrity gasket design, rigid PC/PA housing, and automated air vent locking system maintain stable humidity levels even during long-term storage. Users printing intermittently or switching between multiple spools can rely on preserved filament integrity without repeated drying cycles. This long-term protection is essential for humidity-sensitive materials such as PVA, BVOH, nylon, and composite materials.

RFID Sync for Automatic Drying Profiles and Material Recognition

The AMS HT integrates seamlessly with Bambu Lab’s advanced RFID ecosystem, enabling the system to automatically detect filament type, retrieve the appropriate drying settings, and configure ideal environmental parameters. For Bambu-branded materials, no manual setup is required—temperature, duration, and storage conditions are applied instantly. This automated material-to-profile matching eliminates human error and significantly enhances workflow efficiency. Even during multi-color or multi-material jobs, RFID ensures correct spool selection and drying consistency.

High-Speed Brushless Servo Feeding Motor for Faster Filament Delivery

A major upgrade in the AMS HT is the brushless servo feeding motor, offering up to 60% faster loading speed compared to previous AMS generations. This high-precision motor reduces filament switching delays and improves responsiveness during multi-color print operations. The brushless design ensures minimal noise, reduced vibration, and extended motor lifespan—critical for long, complex, and continuous workflow environments. Its reliability directly contributes to improved extrusion stability and fewer print interruptions.

Bypass Outlet for Flexible Handling of Soft or Brittle Materials

Recognizing that some filaments—especially soft elastomers like TPU 95A, TPE, or brittle composites—may require a more controlled feeding path, the AMS HT includes a dedicated bypass outlet. This secondary, simplified pathway allows sensitive materials to be guided directly to the printer without unnecessary feed angles or tension, significantly reducing jamming risk. This feature expands the AMS HT’s versatility and enables professional users to confidently handle a wider range of polymers.

Enhanced Durability Through Ceramic Filament Inlets

To improve long-term mechanical reliability, the AMS HT utilizes ceramic filament inlets with an impressive Vickers hardness of 1200. These ultra-durable inlets resist wear caused by abrasive composite filaments, including carbon-fiber and glass-fiber reinforced materials. Their high hardness and polished microstructure minimize friction, reduce filament dust accumulation, and maintain smooth feeding performance over thousands of loading cycles.

Advanced Protection and Temperature Safety Systems

Operational safety is ensured through an integrated over-temperature protection system, which includes high-accuracy thermal sensors and hardware-based fail-safe mechanisms. These features prevent overheating and ensure precise temperature control throughout each drying cycle. The system continuously monitors chamber conditions and immediately reacts to any thermal irregularities, safeguarding both the user and surrounding environment.

User-Friendly Status Display and Multi-Platform Monitoring

A clear, real-time digital display provides users with instant visibility of temperature, humidity, and remaining drying duration. Monitoring is also integrated across the Bambu ecosystem, including the printer’s UI, Bambu Studio, and Bambu Handy mobile applications. This unified monitoring framework enables fully remote management and seamless integration within multi-printer production setups.

Scalable Multi-Material Workflow: Up to 24 Filaments

For creators using complex multi-material or multi-color workflows, the AMS HT enables serial connection with AMS 2 Pro and additional AMS HT units. Up to 8 AMS HT and 4 AMS 2 Pro units can be linked, supporting a total of 24 active filaments. This system is ideal for large-scale print farms, prototyping labs, and professional studios producing color-rich or material-intensive parts.

Compatibility Across All Bambu Lab Printers

The AMS HT has been engineered to integrate with the entire Bambu Lab printer portfolio, including X1, P1, A1, and H2 series models.
Note: AMS HT is temporarily not compatible with X1E, but compatibility is expected in future updates.

Technical Specifications Overview

The AMS HT features robust engineering and carefully selected materials such as PC/PA housing certified to UL 94 V-0 flame-retardant standards. With compact dimensions of 114×280×245 mm³, a lightweight profile of 1.21 kg, and extensive support for advanced filaments—including nylons, composites, PC, ABS, ASA, POM, PP, HIPS, PETG, and more—the system is designed for both high performance and broad compatibility.
