Siraya Tech Launches Roamr Line to Power Next‑Gen 3D Printed Shoes

Siraya Tech, based in Los Angeles, has launched Roamr, a new sub‑brand focused on high performance wearables, starting with advanced TPU for 3D printed footwear. The first product, Roamr TPU Air HR (High Rebound), is built to solve one of the biggest problems in 3D printed shoes: choosing between durable but flat‑feeling soles and springy but stiff ones.

Closing the Comfort and Performance Gap

For years, 3D printed shoes have had to pick between standard TPU, which is tough but often feels ‘dead,’ and PEBA elastomers, which feel lively but can be too rigid for comfort. Roamr TPU Air HR is tuned just for footwear, so it can offer both rebound and softness in one material, giving what the brand calls professional‑grade support.

The material is aimed at midsoles, liners, and other parts of the shoe where the foot needs cushioning, stability, and an energetic step at the same time. By dialing in the way the TPU behaves under load, Siraya Tech wants printed shoes to feel much closer to top tier athletic footwear while still being fully 3D printable.

Four Key Technical Features

The new Roamr line is built around four core innovations. First is footwear optimized for high rebound, delivering about 48%–50% rebound, which is designed to remove the ‘mushy’ feeling underfoot and give a more active lift with every step.

Second is ultralight active foaming, which cuts weight by up to 50% at 80A and 57% at 85A, creating an airy feel that helps reduce foot fatigue over time. Third is variable hardness control, where a change in print temperature lets users set hardness between 64A and 85A in a single part, so brands can build softer and firmer zones without changing materials.

Finally, Roamr is designed to avoid the shiny ‘plastic’ look that many 3D prints have. Once foamed, the material delivers a premium matte, textile like surface that is skin friendly and closer to production ready footwear standards.

Two Launch Grades for Different Shoe Zones

At launch, Roamr comes in two hardness options tailored to specific uses in a shoe. Roamr 80A (Comfort Specialist) is meant for plush, high damping midsoles and liners and is available in Noir and Beige, so brands can match performance with lifestyle design.

Roamr 85A (Performance Standard) is the firmer, snappier grade built for outsoles and structural uppers, where grip and durability matter most, and it launches in Noir. The two tier lineup makes it easier for footwear designers to build full shoes around a single TPU family while still getting very different performance in each zone.

Ready for Popular 3D Printers and Global Buyers

On the hardware side, Roamr is tuned for the Snapmaker U1 and the full Bambu Lab series, including A1, P1S, and X1C, to support clog free, high speed, larger scale printing. That means both brands and advanced makers using these printers can move from prototypes toward small batch production with fewer material issues.

Roamr is already available on Amazon US, with global shipping set to start soon, giving designers and small studios in many Countries access to performance footwear materials without long lead times. Siraya Tech continues to position itself as a specialist in resins, silicone, and filaments that help push 3D printing from simple prototyping into real end use products.
