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.
The Bambu Lab AMS HT does not qualify for free shipping.
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.
