ASR 5th Wheel
Fully Automated 5th Filament for Your Bambu A Series Printer
Your Bambu AMS Lite handles four spools. We handle the fifth.
The Bambu A Series Printers with AMS Lite automates four-color printing beautifully — but the moment you need a 5th color or material, the printer pauses and waits for you. Every single time.
The ASR 5th Wheel eliminates that interruption entirely. It mounts directly to your printer's X-axis motor housing, autoloads filament on insertion, maintains tension continuously during printing, and automatically feeds and retracts on command — all without touching your printer.
Walk away. Let it print. Come back to a finished part.
