TPU Filament Buffer – Synchronized Feeding for Flexible 3D Printing

Printing flexible materials such as TPU requires high precision. This buffer unit features electric feed and retraction, synchronized feeding to reduce Bowden tube resistance, and filament break detection for stable, reliable printing with soft TPU 80A–85A. It includes manual control buttons, a quiet motor, and durable construction. Fully compatible with Klipper boards; works with Bambu Lab printers but without filament detection. Signal wiring and firmware setup are required.
