Siraya Tech Roamr TPU Air HR 80A Lilac Filament - 64A-80A Variable Hardness, 48-50% High Rebound, Foaming Flexible 3D Printer Filament, Matte Finish for Footwear 800g

["FOOTWEAR-OPTIMIZED HIGH REBOUND (HR): Specifically engineered for high-performance shoes, Roamr TPU Air HR Lilac 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 in VIBRANT LILAC: Achieve up to a 50% weight reduction compared to standard TPU. This active-foaming technology allows you to create lightweight, \"air-infused\" structures in a sophisticated Lilac shade, reducing foot fatigue while adding a premium, customized look to your footwear designs.","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. Roamr 80A Lilac 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, yoga accessories, and custom prosthetic interfaces.","HIGH-SPEED COMPATIBILITY & STABILITY: Extensively tested on direct-drive systems, including X1C/P1S/A1 and Snapmaker U1. 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."]
