Siraya Tech Siraya Tech Black PEBA Filament - 1.75mm (800g)
The Siraya Tech Rebound PEBA is a next-generation elastic 3D printing filament engineered to bridge the gap between nylon toughness and elastomer flexibility. Lighter and stronger than traditional TPU alternatives, it offers an exceptional 62% (85A) or 78% (95A) energy return. Whether you're prototyping athletic footwear, custom orthotics, protective gear, or robotic end-effectors, PEBA delivers the elastic resilience and chemical durability your application demands.
- Lightweight material properties reduce part weight without compromising performance
- Excellent fatigue resistance for parts that flex and rebound repeatedly over time
- Well-suited for sports gear, robotics, footwear components, and prosthetic applications
- Strong chemical durability resists oils, fuels, and common solvents
Siraya Tech Rebound PEBA Elastic 3D Printing Filament
Next-generation elastomeric filament delivers nylon strength, superior elasticity, and 62% (85A) or 78% (95A) energy return for sports gear, drones, robotics, and outdoor parts.
Exceptional Energy Return for Performance Applications
Rebound PEBA achieves remarkable energy return, meaning parts printed with this filament spring back efficiently after compression or impact. This makes it uniquely suited for applications where stored mechanical energy matters, from athletic insoles and protective gear to robotics actuators and drone landing pads.
- 62% (85A) or 78% (95A) energy return outperforms most standard TPU filaments
- Retains rebound performance across repeated flex cycles
- Ideal for cushioning, impact absorption, and spring-loaded designs
Cold-Weather Flexibility Down to -60°C
Unlike TPU filaments that stiffen or crack in freezing temperatures, Siraya Tech PEBA maintains its elastic properties at temperatures as low as -60°C. This makes it uniquely suited for outdoor gear, cold-climate robotics, winter sporting equipment, and industrial applications where parts must perform in harsh environments.
- Stays pliable and functional at -30°C (85A) & -60°C (95A) without cracking or stiffening
- Outperforms standard TPU in cold-temperature flexibility retention
- Ideal for outdoor, winter sports, and cold-storage industrial applications
Nylon Strength Meets Elastomer Flexibility
Unlike conventional elastic filaments that sacrifice structural integrity for flexibility, PEBA inherits the toughness characteristics of nylon while maintaining true elastomeric stretch and recovery. The result is a material that holds fine printed detail under load and snaps back without deforming permanently.
- 85A/95A Shore hardness balances rigidity with flexible rebound
- Resists tearing and deformation under mechanical stress
- Maintains dimensional accuracy through repeated deformation cycles
Lightweight and Chemically Durable Construction
PEBA as a polymer class is inherently lighter than TPU, giving Rebound PEBA a meaningful weight advantage in applications where every gram counts. Drone frames, wearable brackets, and performance sports components all benefit from the reduced mass without compromising durability or elasticity.
- Low-density PEBA base material reduces finished part weight
- Resists oils, fuels, and common chemical exposure
- Well-suited for medical, industrial, and wearable product applications
