LOS ANGELES, Jan. 22, 2026 /PRNewswire/ — Siraya Tech, a leader in advanced 3D printing materials, today announced Roamr, a specialized sub-brand dedicated to high-performance wearables. Roamr debuts with TPU Air HR (High Rebound), a material engineered to bridge the “performance-comfort void” in the 3D printed shoe industry.
Breaking the Performance Barrier
For years, 3D printed footwear has struggled to balance durable but “dead” standard TPUs against springy but rigid PEBA elastomers. Roamr TPU Air HR is specifically calibrated for footwear, striking the perfect balance between rebound and softness to deliver professional-grade support.
Four Core Innovations:
Footwear-Optimized High Rebound (HR): Delivering 48%–50% rebound, it surpasses standard TPU by eliminating the “mushy” feeling of collapsing soles, providing an active upward thrust with every step.
Ultralight Active Foaming: Achieves significant weight reduction—up to 50% (80A) and 57% (85A)—creating an “airy” structure that minimizes foot fatigue.
Variable Hardness Control: By adjusting printing temperatures, users can tune surface hardness between 64A and 85A. This allows for multi-density zones within a single part while maintaining TPU’s natural flexibility, avoiding the stiffness of nylon.
Professional Textile-Like Finish: Roamr moves beyond the “plastic look” of traditional prints. Once foamed, it presents a premium, skin-friendly matte texture that meets production-level aesthetic standards.
The Debut Lineup
Optimized for footwear anatomy, Roamr launches with two hardness options:
Roamr 80A (Comfort Specialist): Ideal for plush, high-damping midsoles and liners. Available in Noir and Beige.
Roamr 85A (Performance Standard): A snappy, durable formulation for outsoles and structural uppers. Available in Noir.
Excellent Hardware Compatibility
Roamr is optimized for the Snapmaker U1 and the entire Bambu Lab series (A1, P1S, X1C), ensuring clog-free performance for large-scale, high-speed printing.
Roamr is available now on Amazon US, with global shipping starting soon.
