Features
- 4-Slot Auto Feeding & High-Speed Filament Switching: 4 independent material slots for automatic filament switching. Self-developed synchronous servo motor lifts feeding speed by 60%, saving roughly 10 minutes per material swap to speed up multi-color printing production. Up to 4 sets can be cascaded to realize 24-color layered printing for intricate artistic models
- 65C Active Drying & Sealed Moisture-Proof Storage: Max 65C constant temperature heating with sealed airtight storage, efficiently dehumidifying hygroscopic PETG, PA and other prone-to-moisture filaments. Real-time temperature and humidity data can be viewed on printer touchscreen, Bambu Studio and Bambu Handy for precise storage control.
- RFID Smart Filament Identification System: Built-in RFID sensor automatically reads filament type and remaining stock data, recording consumption records intelligently. It eliminates manual material logging, brings convenient material management and avoids printing errors caused by wrong filament matching.
- Durable Ceramic Feeding Inlet & Wide Filament Compatibility: Wear-resistant ceramic bushings reduce friction during long-hour printing to prevent filament jams. Works with 1.75mm PLA, PETG, ABS, ASA, PA, PC and most standard filaments; fits spools with 5068mm width and 197202mm diameter.
- Full Compatibility for Multiple Printer Models & Complete Accessory Kit: Universal design Compatible with Bambu Lab X1, P1, P2, A1, H2D, H2S, H2C series 3D printers. Package includes AMS 2 Pro unit, dedicated desiccant packs, PTFE feeding tubes and 6-pin connection cable for out-of-box assembly.

I used to waste lots of time drying PETG and PA filament separately before every print. Love that this unit keeps filament sealed and dry all the time. No more failed prints caused by damp material. It runs consistently, feeding works smoothly. If you work with moisture-sensitive filaments, this feature alone makes it worth buying.

Had to take apart with the first couple of days to align the main hub so that the PTEF would fit in properly. Shipping took forever and honestly for the price I paid I highly doubt it was new considering it should signs of wear on the housing unit. It definitely isn’t worth what I paid. The Plug Wasn’t even a standard US plug had to buy another one.

Bought this so I could have a second AMS unit. I have 2 other ones that are great. This seller sold me a broken unusable unit.

Been using it nonstop for a while now. Auto filament switching stays reliable every day. Lots of thoughtful details: wear-resistant ceramic openings, moisture-proof storage, smooth auto feeding. All the repetitive work is cut down. Overall user experience is fantastic. If you own a compatible Bambu printer, this is such a practical upgrade.

The RFID sensor automatically reads filament type and leftover material. I no longer mix up filaments or write labels manually. Super low maintenance after setup. Just load four spools and start long prints without constantly checking on the machine. Everything runs hands-off, perfect for hobbyists who hate frequent adjustments.

This feeder works way better than I expected. Switching between four colors is quick and steady, haven’t had any filament jams yet. The color transitions on my printed models look really clean with crisp details. I don’t have to keep stopping the printer to swap spools manually. Those ceramic feed holes also stop filament from wearing down. Definitely speeds up all my multi-color projects.
