Automatic material handling for dry, reliable multi-material printingBambu 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 workflowsThe 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 HTThis 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 printingThe 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.
