About This

• 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.
