The Automatic Material System (AMS) from Bambu Lab is a versatile and innovative tool that allows for multicolor and multi-material 3D printing. By enabling seamless filament transitions, the AMS not only prevents filament runouts but also keeps your filament dry, ensuring uninterrupted printing and minimizing waste.
Each AMS unit consists of 4 filament slots, and up to 4 AMS units can be connected in parallel using the AMS hub, supporting up to 16 colors for truly vibrant and complex prints.
While the AMS is already a well-designed and highly functional system, the spirit of personalization and customization is deeply rooted in the 3D printing community. Makers are always looking for ways to enhance, adapt, and optimize their setups.
To keep the maker in you alive, we’ve curated a selection of the best AMS mods and accessories available. From practical upgrades to creative enhancements, these modifications showcase the endless possibilities for tailoring your AMS to your specific needs and preferences.
The Hydra AMS is an enhanced drop-in main body replacement designed for the Bambu Lab AMS, offering improved spool compatibility and functionality. It serves as a new inner body for the AMS, allowing users to accommodate larger filament rolls. With support for spools up to 75 mm in width and 202.5 mm in diameter, it can handle most 1-kg ones, making it a practical upgrade for users who frequently work with different filament brands. The design includes adjustable rollers in four positions, accommodating spools ranging from 120 mm to 205 mm in diameter; however, for those larger than 201 mm, a printed lid spacer is required.
Printing the Hydra AMS requires attention to detail. The designer suggests a minimum of three walls, as well as three top and bottom layers, and an infill of 15% or higher. A wide brim, such as 10 mm, is also recommended to improve bed adhesion, as the part prints in a tall orientation and may be prone to falling. The great news? It’s designed to print without supports. Due to the heat generated within the 3D printer chamber, ABS or PETG are recommended over PLA to prevent deformation.
The Hydra AMS utilizes the existing internals of the Bambu Lab AMS, requiring users to transfer components such as the four feeder motors, rear motor, front and rear rollers, RFID boards, main board, PTFE tubing, and cables. It retains the standard AMS outer casing, maintaining RFID functionality. The use of 4 x 20 mm cap head M3 bolts is recommended to interlock the three main parts and prevent sliding.
Complete assembly instructions are provided, and third-party YouTube videos are available to guide users through the modification process. If assembled correctly, the mod is reversible and doesn’t damage the AMS. However, it’s important to note that this modification may void the original AMS warranty, and the creator of the Hydra AMS doesn’t provide any warranty for the model. Users should proceed with caution and ensure they are comfortable with the risks involved.
