Overview
The Bambu Lab H2D TPU High-Flow Kit is designed to improve TPU printing performance on the H2D and H2D Pro. By reducing extrusion resistance and extending the melting zone, this kit enables faster and more stable flexible-filament printing, especially for Bambu TPU materials.
This kit includes both 0.4 mm and 0.6 mm TPU High-Flow hotends along with the required installation components, making it a practical upgrade for users who want stronger TPU workflow performance without extensive manual tuning.
Reliable High-Speed TPU Printing
The specially designed hotend reduces extrusion resistance and extends the melting zone, enabling faster and more stable TPU printing. When printing 90A TPU, it delivers up to 100% higher flow rate and cuts print time by around 30% for typical applications such as footwear.
Specially Tuned for Bambu TPU Filaments
Print parameters are precisely fine-tuned for all Bambu TPU filaments when used with the TPU High-Flow Kit. No manual tweaking required—allowing sticky TPU materials to print smoothly right out of the box.
Easy Installation
Installation takes just a few minutes. Simply pop off the front cover, remove the filament cutter, and slide in the High-Flow hotend—ready to print in no time.
