Active Filament Drying:

• AMS HT can actively dry filament at temperatures up to 85°C.

• Suitable for preparing moisture-sensitive materials before printing.

• Rotating spool drying helps expose different sections of the filament spool to the circulating heat.

• Active moisture discharge removes moisture from inside the drying chamber during the drying process.

• Different supported materials can use appropriate drying modes according to their requirements.

• Drying performance depends on filament material, moisture level, ambient humidity, spool condition and drying duration.

Airtight Filament Storage:

• After completing a drying cycle, AMS HT can maintain an airtight storage environment.

• Airtight storage helps reduce moisture reabsorption from surrounding air.

• This is particularly useful for moisture-sensitive materials such as PA, PVA, BVOH and PC.

• Keeping filament enclosed after drying can help maintain its condition before and during printing.

• Desiccant is included to assist with moisture control inside the storage environment.

Temperature and Humidity Monitoring:

• The integrated front display provides real-time information about the filament environment.

• Displays internal temperature.

• Displays humidity level.

• Displays remaining drying time.

• Users can monitor drying progress directly from the AMS HT without requiring additional software for basic status information.

• Continuous monitoring helps users understand the current drying conditions.

Rotating Drying Mode:

• The filament spool rotates during the drying process.

• Rotation helps distribute heat more evenly around the spool.

• More consistent exposure to heated air can improve drying uniformity.

• The system is designed to combine spool rotation, heating and active moisture discharge during drying.

Electromagnetic Air Vent:

• AMS HT uses an electromagnetic air vent as part of its moisture removal system.

• The vent is controlled according to the device's drying operation algorithms.

• Controlled airflow assists active moisture discharge during drying.

• The system can transition to airtight storage after the drying cycle.

Automatic Filament Feeding:

• AMS HT automatically feeds filament to a compatible Bambu Lab printing system.

• The brushless servo drive provides controlled filament movement.

• Automatic feeding reduces the need for manually pushing filament through the material path.

• The system can automatically manage filament switching during supported multicolor printing workflows.

RFID Filament Identification:

• Compatible Bambu Lab RFID filament spools can be automatically recognized.

• RFID identification can provide material information to the connected Bambu Lab ecosystem.

• Automatic recognition reduces manual material configuration for compatible RFID-tagged spools.

• RFID functionality depends on using compatible Bambu Lab RFID filament.

Filament Odometry:

• Filament Odometry provides automatic measurement of filament movement and length.

• It helps the system monitor filament feeding during operation.

• Automatic filament measurement can improve material management and feeding control.

• This feature is particularly useful for automated printing workflows.

Supported Filament Materials:

AMS HT supports a wide range of 1.75mm filaments, including:

• PLA

• PETG

• ABS

• ASA

• PET

• PA

• PC

• PVA when properly dried

• BVOH when properly dried

• PP

• POM

• HIPS

• Bambu PLA-CF

Bypass Filament Outlet:

The dedicated bypass filament outlet is designed for compatible materials that should not be routed through the standard AMS feeding mechanism. Supported bypass materials include:

• TPE

• Universal TPU

• Bambu PET-CF

• Bambu TPU 95A

• Other compatible carbon-fiber-filled materials

• Other compatible fiberglass-filled materials

Always verify filament compatibility with the connected Bambu Lab printer and AMS configuration before printing.

Unsupported Materials:

• PVA in wet condition

• BVOH in wet condition

PVA and BVOH should be properly dried before use when supported by the system. Moisture-sensitive filament can absorb significant moisture from ambient air, particularly in humid environments.

Multi-Color and Multi-Material Printing:

• AMS HT integrates with the Bambu Lab automatic material management ecosystem.

• Multiple compatible AMS units can be connected through cascading connections.

• A compatible configuration can support up to 24 colors or materials.

• Automatic material switching can occur according to the requirements of a supported multicolor print.

• This is useful for multicolor models, multi-material prints and automated filament management.

• Actual maximum color/material capacity depends on the complete Bambu Lab printer and AMS configuration.

Spool Compatibility:

• Compatible filament diameter: 1.75mm

• Supported spool width: 50–68mm

• Supported spool diameter: 197–202mm

• Check spool dimensions before inserting filament.

• Ensure the spool can rotate freely inside the AMS HT.

• Filament spool shape and material winding should allow reliable automatic feeding.

• Third-party filament spools should be checked for physical compatibility before use.
