Bambu Lab TPU 95A HF Filament 1.75mm 1KG – High Flow Flexible Filament for Fast Printing
Bambu Lab TPU 95A HF (High Flow) is an optimized flexible filament designed for high-speed printing. With a melt index higher than some PLA filaments, TPU 95A HF offers approximately 3x faster printing speeds compared to standard TPU, solving the common problem of lengthy print times with flexible materials. Despite the speed improvements, it maintains the exceptional interlayer adhesion, impact resistance, and flexibility expected from premium TPU.
Perfect for phone cases, wearables, gaskets, protective covers, and any prints requiring both flexibility and toughness. The high flow formula works reliably with direct drive systems (NOT AMS compatible – load filament directly into printer).
Bambu Lab TPU 95A HF Key Features
- 3x Faster Printing – High flow formula enables rapid TPU printing
- Shore 95A Hardness – Firm yet flexible rubber-like feel
- Excellent Impact Resistance – Withstands collision and drops
- Strong Layer Adhesion – Reliable interlayer bonding at high speeds
- Cold Temperature Resistant – Maintains flexibility in cold conditions
- RFID Enabled – Auto-detection with Bambu Lab printers (Direct Drive only)

TPU 95A HF Printing Tips
- Dry Before Use – TPU 95A HF is highly moisture-sensitive. Dry at 70°C for 8 hours.
- Use Hardened Nozzle – Hardened steel 0.6mm recommended for best results.
- Direct Drive Only – NOT compatible with AMS or AMS Lite due to flexible material feeding issues.
- Storage – Store with desiccant; reseal immediately after use.
- Test Settings – Start with RFID auto-settings and fine-tune if needed.

Bambu Lab TPU 95A HF FAQ
Q: How much faster is TPU 95A HF compared to regular TPU?
A: TPU 95A HF prints approximately 3 times faster than standard TPU 95A. The high flow formula achieves speeds more comparable to rigid filaments while maintaining flexibility.
Q: Is TPU 95A HF compatible with the AMS?
A: No, TPU 95A HF is NOT compatible with AMS or AMS Lite. Flexible materials like TPU cause feeding issues in the AMS system. Use direct drive feeding only (load filament directly into the printer, bypassing AMS).
Q: Why is drying so important for this filament?
A: TPU 95A HF is highly sensitive to moisture. Wet filament causes bubbling, poor layer adhesion, and stringing. Always dry before printing and store with desiccant.
Q: What nozzle should I use?
A: Use a hardened steel nozzle (0.4mm, 0.6mm, or 0.8mm). Stainless steel also works but is not the first choice. Avoid brass nozzles for extended use.
Q: How flexible is Shore 95A?
A: Shore 95A is moderately flexible – think of a shopping cart wheel or firm rubber band. It’s flexible enough for phone cases and gaskets but not as soft as 87A or 83A materials.
