TPU for AMS vs Standard TPU Comparison

TPU for AMS Applications

• Phone Cases – Impact-resistant protective cases
• Gear Seals – Flexible sealing components
• Stoppers & Bumpers – Vibration dampening parts
• Multicolor Flexible Parts – AMS-enabled color mixing
• Functional Prototypes – Durable flexible designs
• Tool Grips – Comfortable ergonomic handles

Printing Tips

1. Dry before printing – TPU is moisture-sensitive; drying reduces stringing and improves surface finish.
2. Use a 0.4mm+ nozzle – Smaller nozzles are more likely to clog and are not recommended.
3. Dial in flexibility with walls/infill – More walls and higher infill reduce flex; fewer walls increase flex.
4. Keep retraction conservative – Too much retraction can cause feeding issues in flexible materials.

Bambu Lab TPU for AMS FAQ

Q: Is this softer or harder than regular TPU?
A: TPU for AMS has 68D Shore hardness, making it harder than standard 85A-95A TPU. It’s more rigid while still being flexible—ideal for impact-resistant parts rather than super-soft applications.

Q: Can I use this for multicolor prints?
A: Yes! That’s a key advantage. TPU for AMS works seamlessly with the AMS system, enabling true multicolor flexible prints that were difficult with traditional TPU.

Q: Why is this faster than other TPU?
A: Bambu Lab optimized the formulation for higher-flow printing. The harder composition and reduced stringing can support significantly higher speeds than softer TPU profiles (profile-dependent).

Q: Do I need to dry TPU for AMS before printing?
A: Yes. Dry TPU before printing and store it with desiccant (or print from a dry box) to reduce stringing and improve consistency.
