About This

• FOOTWEAR-OPTIMIZED HIGH REBOUND(HR): Specifically engineered for shoes, Roamr TPU Air HR offers a rebound resilience of 48%–50%. This provides significantly higher energy return than typical foaming filaments, ensuring that printed midsoles and insoles offer the "bounce" and responsiveness needed for athletic performance and long-term comfort.
• ULTRALIGHT ACTIVE FOAMING: By utilizing active-foaming technology, this material can achieve up to a 50% weight reduction compared to standard TPU. This allows designers to create lightweight, "air-infused" structures that reduce foot fatigue without sacrificing the structural integrity of the shoe.
• VARIABLE HARDNESS CONTROL: Gain total control over the "squish" of your prints. By adjusting your printing temperature, you can dial in a surface hardness between 64A and 80A. This allows you to print a single part with different density zones—softer in the heel for impact and firmer in the arch for support.
• PREMIUM MATTE & SKIN-TOUCH COMFORT: Eliminate the cheap, shiny "plastic" look of traditional TPU. Roamr 80A prints with a sophisticated, non-tacky matte finish that feels soft against the skin. It is the ideal choice for wearable applications requiring direct skin contact, such as sandal straps, inner linings, and prosthetic interfaces.
• TRUE FUNCTIONAL PROTOTYPING: Designed for the rigorous standards of footwear designers and engineers. Whether you are validating a new sneaker midsole, creating custom orthotics, or building durable cosplay props, this material delivers the structural consistency needed to take a design from a digital file to a street-ready product. And it has obtained RoHS and REACH certifications.
• OPTIMIZED FOR HIGH-SPEED EXTRUSION: Tested extensively for stability on direct-drive systems, including Snapmaker U1 & Entire X1C/P1S/H2D/H2C (hardened gears recommended). Roamr 80A handles retraction better than generic foaming TPUs, reducing stringing. Recommended printing temperature: 220–260°C; keeping filament dry is essential for optimal foaming performance.
