TPU Filament Buffer – Synchronized Feeding for Flexible 3D Printing

Printing flexible materials like TPU demands precision. This buffer unit provides guided electric feed/retraction, automatic synchronized feeding to reduce Bowden tube resistance, and integrated filament break detection—helping you achieve faster, more reliable prints with softer grades (80A–85A TPU).

Key Features:

• Electric feed/retraction with manual control buttons
• Synchronized feeding to support faster print speeds and reduce compression
• Filament break/runout sensor for automatic print pause on failure
• Quiet motor and durable design for extended printing sessions

Compatibility: Fully compatible with Klipper-based mainboards. Works with Bambu Lab printers (filament detection not supported on Bambu systems). Requires signal wire connection and firmware configuration.

Note: Speed improvements vary by printer model, firmware, filament type, and calibration. Proper setup required for optimal results.
