Kexcelled’s New PEBA, TPU Air & Matte 95A Tackle Flexible Printing’s Biggest Challenges
Next-generation flexible materials deliver energy return, lightness, and a premium finish for advanced creators.
Kexcelled has launched a trio of new flexible filaments – K9 PEBA, K8 TPU Air, and K8 TPU 95A Matte – expanding the possibilities of elastomer 3D printing. The company, known for its focus on high-performance polymers, continues to blur the line between engineering-grade materials and accessible production tools.
Each of the new filaments targets a different challenge in flexible printing: energy efficiency, weight reduction, and surface finish. Together, they mark a step forward for designers, engineers, and R&D teams seeking dynamic, functional, and visually refined printed parts.
TPU Air and TPU 95A are available now and PEBA will be available early 2026. Visitors to Formnext 2025 in Frankfurt can experience these materials firsthand at Hall 12.1, Stand C22
K9 PEBA – Energy Return Meets Durability
K9 PEBA is one of Kexcelled’s most advanced flexible filaments to date. Built for professional applications that demand both elasticity and resilience, it offers exceptional energy return, low density, and superior abrasion resistance. Available in 90A, 85A, and 75A Shore hardness levels, it provides a broad range of flexibility and rebound performance.
PEBA (polyether block amide) stands out for its dynamic properties. It stretches, compresses, and returns to shape with minimal energy loss. This makes it ideal for footwear midsoles, sports equipment, orthotics, and vibration-damping components, where consistent rebound and fatigue resistance are critical.
Compared with standard TPU, K9 PEBA’s lower density translates to lighter parts without sacrificing mechanical strength. In additive manufacturing, that means less weight and more efficiency – a valuable combination for product designers testing new geometries or weight-sensitive prototypes.
K8 TPU Air – Foaming Innovation
K8 TPU Air redefines what’s possible in flexible filament design. Described as “Foaming TPU,” this material offers variable density and hardness controlled directly through print temperature. As the filament heats, it expands – producing a foamed internal structure that reduces weight and creates soft, even buoyant parts.
At lower temperatures, the filament behaves like a standard flexible TPU. Increase the temperature, and it begins to foam, achieving hardness levels as low as 56A from its original 86A range. This gives users the ability to fine-tune part softness, energy absorption, and weight without changing materials.
The result is a single filament capable of producing everything from firm, durable prototypes to ultra-light cushioning structures. For athletic gear, protective padding, or wearable prototypes, K8 TPU Air provides freedom that traditional elastomers can’t match. Its variable hardness and low-density output also make it a strong choice for lightweighting experiments and applications where buoyancy is a design advantage.
K8 TPU 95A Matte – Refined, Professional Surface Finish
Kexcelled’s K8 TPU 95A Matte builds on the reliability of the company’s proven 95A formulation while introducing a distinct matte surface finish. The result is a flexible filament that maintains the classic TPU toughness and elasticity but produces parts with a smooth, premium appearance.
This finish naturally conceals layer lines, making parts look injection-molded straight off the printer. It’s especially useful for visible or consumer-facing components, such as wearables, soft-touch handles, and prototype housings that must look production-ready.
Beyond appearance, the K8 95A Matte retains the core benefits of the original 95A TPU – high layer adhesion, chemical resistance, and excellent fatigue life. It’s designed for consistent results across printers and remains one of the most reliable flexible materials in its class.
Flexible Printing for the Next Generation
Across all three filaments, Kexcelled emphasizes performance, control, and usability. K9 PEBA brings engineering-grade elasticity with reduced weight and unmatched rebound. K8 TPU Air delivers tunable density and softness for creative and functional flexibility. K8 TPU 95A Matte offers the same reliability professionals expect from TPU, but with a refined, visually smooth finish.
Together, they cater to advanced users, prosumers, and R&D teams in industries such as footwear, athletic equipment, automotive, robotics, and medical devices – sectors where flexible materials must perform as much as they impress.
