Bambu H2D TPU High-Flow Kit — Faster, More Reliable TPU Printing

High-Speed TPU • Smoother Extrusion • Drop-In Upgrade

Overview

The Bambu H2D TPU High-Flow Kit is a dedicated hotend upgrade designed to significantly improve TPU printing performance on H2D series printers. By reducing extrusion resistance and extending the melt zone, it allows flexible filaments to print faster, cleaner, and more consistently.

When paired with Bambu TPU materials, this kit delivers higher flow rates and up to ~30% faster print times, making it ideal for production-style TPU printing.

Why choose the TPU High-Flow Kit

• Faster TPU printing: Up to ~30% shorter print times
• Higher flow rates: Improved extrusion for flexible materials
• Smoother results: More consistent layers with reduced under-extrusion
• Tuned for Bambu TPU: Pre-optimized profiles for reliable results
• Easy install: Quick swap with included components
• Includes 0.4 mm & 0.6 mm hotends

Improve TPU reliability even further (Recommended)

For best results, pair this kit with the TPU Feed Assist Module.

• Actively feeds TPU to reduce drag and slipping
• Improves consistency on longer or complex feed paths
• Helps prevent under-extrusion and jams
• Ideal for side-mounted dry boxes or longer tubing setups

👉 Recommended for frequent TPU users or production printing setups

Important limitations (read before buying)

• TPU only: Do NOT print PLA, PETG, or hard filaments (will damage coating)
• No filament cutter: Cutter function is disabled when installed
• No auto filament handling (right nozzle): No auto feed/retract or switching
• Right nozzle only: Installing on left nozzle will cause issues
• Single-material use: Designed specifically for TPU workflows

Recommended setup

• Nozzle options: 0.4 mm (detail) / 0.6 mm (speed & flow)
• Material: Bambu TPU 85A / 90A / 95A / 95A HF
• Profiles: Use Bambu presets for best results
• Dry filament: Strongly recommended for TPU

Printing tips

• Use 0.6 mm nozzle for maximum speed gains
• Keep TPU dry to avoid stringing and poor surface finish
• Slower retraction speeds improve consistency
• Avoid aggressive travel moves to reduce oozing

Typical use cases

• Footwear and wearables
• Gaskets, seals, and vibration-dampening parts
• Flexible hinges and protective components
• Production TPU printing where speed matters
