Siraya Tech, a 3D printing material producer, introduces three elastomer materials: TPU Air, TPU 64D, and Rebound 55A.
Key features of TPU Air
The TPU Air is an active foaming TPU filament which allows users to control the material’s final weight (thanks to temperature-controlled foaming) and softness by adjusting print temperature. This results in parts up to 50% lighter than standard TPU.
The material’s shore hardness can be varied from approximately 63A to 85A, tailoring parts to specific application needs. It delivers a fabric-like matte finish right after the printing process.
Its primary applications include functional parts such as drone components and ergonomic grips, custom padding and liners, vibration dampeners, and unique wearables or cosplay elements where a soft texture is desired.
“TPU Air isn’t just a new filament; it’s a new way to think about creating flexible parts,” says Mark Peng, Founder of Siraya Tech. “The ability to tune weight and softness on-the-fly opens up incredible possibilities for designers and engineers, allowing for unprecedented customization in applications ranging from performance sporting goods to bespoke assistive devices.”
Key features of TPU 64D
For applications demanding greater rigidity and wear resistance without sacrificing the benefits of an elastomer, Siraya Tech introduces TPU 64D. This filament offers a Shore 64D hardness, providing structural stability for industrial-strength parts.
Designed for easier printing than many softer TPUs, it has undergone ISO 10993 testing for specific biocompatibility protocols (-5, -10, -23), potentially expanding applications in external-use devices (end-user validation required).
Siraya Tech said it works well with the original Bambu Lab Automatic Material System.
It’s ideal for gears, rollers, protective covers, and bushings that require durability.
Key features of Rebound 55A resin
The Rebound 55A is a highly flexible and elastic resin (Shore 55A) engineered for significantly faster rebound—3 to 5 times faster than typical elastomers. According to the company, it excels at withstanding bending and compression and rapidly resuming its original shape.
Ideal for parts requiring shock absorption and rapid shape recovery, it delivers the detailed results expected from resin printing. Key applications it might enable, include protective gear elements, cushioning pads, dampeners, seals, gaskets, flexible grips, and sports equipment components.
“The launch of TPU Air, TPU 64D, and Rebound 55A resin demonstrates our ongoing dedication to providing material solutions that meet specialized needs,” added Mark Peng. “We are excited to see how these new elastomers will empower our users to innovate further in their respective fields, from industrial design to advanced hobbyist applications.”
