Bambu TPU Assist Module for TPU 95A Printing

The Bambu TPU Assist Module is designed to improve printing reliability with common TPU materials such as TPU 95A and, in suitable setups, around 90A TPU—not to make very soft TPU effortless. It works as a remote auxiliary feeding device: when tension builds during printing, the module automatically feeds a small amount of filament toward the printer to reduce pulling force on the extruder. This helps prevent TPU from being squeezed, deformed, or jammed inside the extruder, improving print success rates for flexible parts. When paired with a Bambu Lab TPU nozzle and a well-tuned filament path, it can also help support a moderately higher TPU flow rate. Results still depend on TPU hardness, dryness, routing, calibration, nozzle condition, and printer setup.
