Product Features Multi-Colors/materials Capability Keep Filament Dry Filament Runout & Winding Detection AMS Filament Backup Note: If you plan to connect multiple AMS units together, you will need to purchase the AMS Hub. Compatibility: X1 Series and P1 Series Make Multi-Color 3D Printing Real Color, the ultimate expression of emotions, is brought to you by Bambu Lab's Automatic Material System (AMS). You can now enjoy printing freely in multiple colors and materials. Multi-Material Printing Applicable to most materials such as PLA, ABS, ASA, PETG, PC, etc. Hassle-Free Support Removal With AMS, Bambu Lab printers can use snap-away support material or dissolvable filament to minimize the pain of removing supports. No More Filament Leftover Without AMS, when the filament runs out, manual spool replacement interrupts printing and results in wasted filaments. With AMS, there is a seamless transition to a new spool which keeps uninterrupted printing and minimizes waste. Filament Backup Your print never stops with automatic spool changing. With AMS filament backup function, never worry about running out of filament during your sleep or absence, ensuring a seamless and uninterrupted printing process, preventing any filament waste and promoting energy efficiency. Advanced Intelligent System Powered by a 32-bit MCU, sensor arrays, actuators, and a smart algorithm, the AMS has reached unprecedented levels of intelligence. It expertly manages filament loading and unloading, along with efficient fault detection and recovery. Filament Winding Detection When the filament at the tool head encounters resistance, it may be that the filament is tangled or the spool is stuck, AMS can detect it immediately and suspend printing to avoid empty printing. Say Goodbye to Wet Filaments Filament that has absorbed moisture can lead to print quality issues and poor layer adhesion, or even nozzle clogging that can lead to a failed print. Keep the Filament Dry The AMS has an air-tight seal and with the help of dessicant material, it absorbs moisture to keep the moisture away from Filament. A Humidity Sensor also detects the humidity inside the AMS and provides information to the user when the humidity is higher or the dessicant may need to be replaced. For best print quality, dry filament is required.
