2 Independent Filament Drying Chambers: Tetras upgrades your Bambu Lab AMS into a professional 4-lane filament dryer. Each chamber provides 3D printer filament spool with its own heater, fan, temperature sensor, and humidity sensor, allowing simultaneous drying of PLA, ABS, PETG, TPU, and other 3D printer filaments with optimal settings for multi-material printing. *Compatible with Bambu Lab AMS Gen1. For AMS Pro2, please print the required adapter (not included)
Dry Filament While Printing: Keep your filament in peak condition during printing. Each chamber supports independent temperature control from 20℃–65℃ (68°F–149°F) and adjustable filament drying time from 30 minutes to 24 hours or unlimited, reducing stringing, warping, and extrusion issues for 3D printer filament.
Active Drying with Moisture Exhaust: Each filament drying chamber features active air circulation and automatic moisture exhaust, efficiently removing humidity from PLA, ABS, PETG, TPU, and other filaments. The cover opens during drying to release moisture and seals afterward to prevent filament moisture from ambient exposing.
Automatic Sealing & Humidity Control: After drying, Tetras automatically seals each filament chamber and maintains a stable low-humidity environment, protecting your 3D printer filament for long-term storage. Filament stays dry, secure, and print-ready without repeated drying cycles.
Two-Stage Drying & Easy Independent Installation: Tetras uses a two-stage filament drying process—high-efficiency moisture removal followed by stable preheating and conditioning—to ensure smooth filament feeding and consistent extrusion. Designed as a drop-in AMS filament dryer upgrade, it installs independently without firmware conflicts or permanent modifications.
