Ultrafuse® Foaming TPU
Less Material, More Output, Meet our Foaming TPU
Thank you for trying our sample product. We’re excited that you are testing our new Ultrafuse® Foaming TPU filament: Unlock the performance potential of foamed prints with lightweight flexibility, leather-like surfaces, and excellent shock absorption.
Material Details

Super Powers
- Less Material, More Output Achieve similar performance with 50% less material due to Foaming Properties
- High Speed Printing, up to 20 mm³/s faster than Bambu Lab TPU and PLA
- Leather-like Feel & Matt finish, exceptional surface smoothness, seamless, high quality finish
- No Drying required! Easy Printing & Filament handling
- Watertight at atmospheric pressure, due to the material’s closed-cell foam structure
- Shore hardness 25 - 70A
- Lightweight with adjustable density
- High Flexibility & Elasticity
- Exceptional Damping, absorbs shocks and vibrations
Meet Foaming TPU
Ultrafuse® Foaming TPU, is an advanced 3D printing material that combines the flexibility of TPU with the weight reduction properties of foamed materials. This filament contains an integrated foaming agent that activates at printing temperatures, creating microscopic air pockets within the printed object. The result is lightweight, elastic, and impact-resistant material.
The material expands during printing, reducing material usage and weight. By using different print settings configurations, users can control the expansion ratio and density of the final part.
Less Material, More Output, and cut costs while you’re at it
Thanks to it’s expansion rate of up to 100%, Ultrafuse® Foaming TPU allows you to use up to 50% less filament for the same part volume. That means when you buy 1 kg of Ultrafuse® Foaming TPU, you can print as much as you normally would with 2 kg of standard TPU.
Less material in, same performance out, smart, efficient, and cost-effective. And on top of that the printing speed outperforms high-speed materials such as PLA. Meaning that you can also reduce time! How? By the reduction of printing time by using standard print speeds in combination with increased layer heights and line width.
