Siraya Tech unveils elastomer 3D printing materials, led foaming TPU Air

Siraya Tech launched three new elastomer 3D printing materials: TPU Air, TPU 64D, and Rebound 55A resin. These materials represent a leap forward in flexibility, durability, and user control for professionals and enthusiasts seeking high-performance solutions. With this release, the company deepens its mission to empower creators by offering unprecedented options in both filament and resin formats.

TPU Air is the star of this new lineup, introducing a novel approach to flexible 3D printing. As an active foaming TPU filament, TPU Air redefines how light and soft flexible parts can be. Unlike conventional TPU materials, which come with fixed densities and hardness, TPU Air responds to print temperature, allowing users to tailor the final characteristics of their prints. This tunability enables significant weight reductions—up to 50% lighter than traditional TPU—and an adjustable Shore hardness range from approximately 63A to 85A. Furthermore, its soft, fabric-like matte finish distinguishes it aesthetically, offering a tactile appeal that is both practical and pleasing. Applications are wide-ranging, including drone components, ergonomic grips, custom padding, and wearable items that benefit from a lightweight, flexible structure. The ease of printing also sets TPU Air apart, making it more accessible to users previously deterred by the complexity of flexible filaments.

“TPU Air isn’t just a new filament; it’s a new way to think about creating flexible parts,” said 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.”

Accompanying TPU Air is TPU 64D, a filament engineered for users who need a tougher, more rigid material without losing the core benefits of elastomers. With a Shore hardness of 64D, TPU 64D brings structural reliability. It is especially suited for parts that require durability under mechanical stress, such as gears, rollers, and bushings. Its enhanced wear resistance makes it ideal for demanding environments, while its smooth printing behavior reduces issues like clogging, which are often encountered with softer TPU filaments. TPU 64D has also undergone ISO 10993 testing protocols for biocompatibility, indicating its potential in external-use devices, pending user validation. Notably, it is compatible with the Bambu Lab AMS system, further streamlining its integration into advanced 3D printing setups.

Siraya Tech also introduced Rebound 55A, a high-performance flexible resin that achieves both elasticity and rapid shape recovery for resin printer users. With a Shore hardness of 55A, Rebound 55A delivers rare flexibility in resin materials while maintaining the detail and precision that resin printing is known for. Its rapid rebound rate—up to five times faster than typical elastomers—ensures that parts can endure compression and bending with swift recovery, making it ideal for dynamic and high-stress applications. This includes cushioning pads, flexible grips, gaskets, dampeners, and components for sports equipment. Its single-part composition simplifies the user experience, eliminating the need for complex resin mixing.

By developing these three advanced materials, Siraya Tech is charting a course toward greater functionality and performance in 3D printing. These new offerings reflect an acute understanding of the market’s evolving demands and a proactive stance in addressing them with innovative, reliable solutions.

The newly launched TPU Air, TPU 64D, and Rebound 55A are currently available in the United States through Amazon, with plans to expand availability through the official Siraya Tech website and in international markets soon. As the 3D printing community continues to grow and diversify, these elastomers are poised to become essential tools in the hands of designers, engineers, and creators eager to push the limits of what flexible materials can achieve.
