Automatic material handling for dry, reliable multi-material printing

Bambu Lab AMS HT is an automatic material system built to improve multi-material 3D printing with fast, even filament drying and smooth, reliable feeding. The unit is purpose-built for high-performance and moisture-sensitive filaments, helping reduce moisture-related print issues and support more stable extrusion.

Key features for filament drying, feeding, and storage

• High-temperature drying up to 85 °C: removes moisture efficiently to support more stable prints and better material performance.
• Electro-magnetic air vent: enables rapid dehumidification during drying, then switches to airtight storage afterward.
• Brushless servo feeding: supports faster, more consistent filament loading and material swaps.
• RFID auto-sync: reads official Bambu spools to simplify setup.
• Status display and protections: shows temperature, humidity, and remaining time, with safe-heat safeguards built in.
• Rotational drying: helps reduce hot and cold spots for more uniform drying results.

Expandable material capacity for advanced colour workflows

The AMS HT supports larger multi-material workflows through series expansion. AMS units can be connected together, including combinations such as AMS 2 Pro with AMS HT, to unlock up to 24 filament inputs for complex jobs and colour-rich prints.

Filament types suited to the AMS HT

This material system is designed for demanding filaments that benefit from controlled drying and low-humidity storage. Suitable materials listed in the original product information include nylons, PET-based materials, PC/ABS, and carbon-fibre or glass-fibre reinforced blends.

Why makers and technical users choose the AMS HT

• Faster swaps: helps keep multi-material jobs moving with less interruption.
• Fewer moisture-related failures: supports more dependable printing with hygroscopic materials.
• Cleaner, more predictable extrusion: especially useful for technical filaments.
• Modular expansion: suited to users building more serious multi-material production setups.

Use cases for high-performance and colour-heavy printing

The Bambu Lab AMS HT is well suited to engineering materials, reinforced composites, and other filaments that can absorb moisture during storage. It also fits multi-colour and multi-material projects where consistent feeding, streamlined spool recognition, and expanded filament capacity matter.

For users printing functional parts with nylon, PET-based materials, or PC/ABS, the drying and airtight storage functions help maintain lower humidity between prints. For larger colour-count prints, slicer planning for purge and cut strategies can help reduce waste while taking advantage of expanded AMS input capacity.

Practical use tips for better AMS HT results

• Store spools inside the unit between prints to help keep humidity low.
• Follow recommended drying temperatures for each material to help preserve polymer properties.
• For large multi-colour jobs, plan purge and cut strategies in your slicer to reduce waste.
