4-in-1 Filament Buffer Hub Kit for Bambu Lab 3D Printers – Replace AMS Hub, Multi-Color Printing Expansion, Includes AMS Buffer and PTFE Adapter, Supports 4-Input 1-Output for X1/P1P/P1S

The 4‑in‑1 Filament Buffer Hub Kit is the ultimate upgrade for makers who want to push the boundaries of multi‑color 3D printing. By merging the AMS Filament Buffer with a 4‑to‑1 Y‑Splitter Adapter, this kit replicates the functionality of the official Bambu Lab AMS Hub at a fraction of the cost, while maintaining 100% compatibility and performance.

• 4-IN-1 FUNCTIONALITY – This kit combines an AMS Filament Buffer and a 4-in-1 PTFE Adapter to create a complete 4‑input, 1‑output buffer hub. It allows you to connect up to four filament sources (multiple AMS units or external spools) to your printer while maintaining smooth, tension‑controlled feeding.
• PERFECT COMPATIBILITY – Designed as a direct replacement for the official Bambu Lab AMS Hub, it works seamlessly with Bambu Lab X1, X1C, P1P, P1S, and other models that use the AMS system. Expand your printer’s capability without buying expensive proprietary parts.
• RELIABLE FILAMENT BUFFERING – The included AMS buffer features a precision spring‑loaded mechanism and a Hall sensor to monitor filament movement. It absorbs tension fluctuations from multiple sources, preventing jams, tangles, and “filament buffer signal lost” errors.
• EASY INSTALLATION – The kit comes with both essential components. Simply connect the 4 in 1 PTFE Adapter inputs to your AMS units or external spools, then link its single output to the buffer, and finally connect the buffer to your printer. No special tools required – just standard PTFE tubes
• UNLOCK 8‑COLOR / 16‑COLOR PRINTING – Combine with one AMS and more for 8‑color prints, or daisy‑chain up to four AMS 2 Pro units for an incredible 16‑color palette. The buffer ensures every filament change is stable and precise.
• The Package Contains: 4 in 1 PTFE Adapter×1，AMS Filament Buffer×1，PTFE Tube 4*2.5mm*6.6FT×1，PTFE connector×3，Non-official 4-pin cable×1，Non-official 6-pin cable×1
