High-performance PEBA filament for durable flexible engineering parts

VARIOSHORE PEBA 45D/90A NATURAL is a premium engineering-grade flexible filament based on Polyether Block Amide (PEBA). Designed for demanding FDM 3D printing applications, this material combines lightweight performance with excellent durability, high resilience and exceptional energy return.

With a Shore hardness of 45D / 90A, this PEBA grade offers increased rigidity compared to softer flexible materials while maintaining the flexibility required for dynamic and functional components. The result is strong, lightweight parts that recover quickly after repeated bending, compression and impact.

Compared to standard TPU filaments, PEBA provides higher rebound, improved fatigue resistance and better long-term mechanical performance, making it an excellent material for professional engineering applications.

Why choose VARIOSHORE PEBA 45D/90A?

VARIOSHORE PEBA is developed for users looking for a high-performance flexible filament that combines strength, resilience and lightweight construction. It delivers reliable mechanical properties for demanding functional parts that experience continuous movement or repeated loading.

• Excellent energy return and rebound
• Lightweight engineering material
• Higher stiffness than softer PEBA grades
• Outstanding fatigue resistance
• Excellent abrasion resistance
• Fast elastic recovery after deformation
• Maintains flexibility at low temperatures
• Good resistance to oils, greases and many industrial chemicals

These properties make PEBA an excellent alternative to conventional TPU whenever higher performance, lower weight and greater durability are required.

Balanced flexibility and structural support

One of the key advantages of PEBA is its exceptional rebound performance. After compression or flexing, printed parts quickly recover to their original shape while efficiently returning stored energy. This creates components with a responsive, spring-like feel that is difficult to achieve with traditional TPU materials.

The 45D / 90A hardness provides additional structural support for applications requiring increased dimensional stability without sacrificing the flexibility needed for dynamic movement and impact absorption.

Designed for demanding functional applications

Thanks to its excellent balance between flexibility and stiffness, VARIOSHORE PEBA 45D/90A NATURAL is suitable for a wide range of engineering and end-use applications.

• Performance footwear and midsoles
• Orthotics and insoles
• Sports equipment
• Robot grippers and soft robotics
• Flexible machine components
• Industrial seals and gaskets
• Protective equipment
• Shock absorbers and vibration dampers
• Bicycle components
• Wearable products
• Functional prototypes

Reliable printing and long-term performance

Like other engineering-grade PEBA materials, VARIOSHORE PEBA performs best when printed dry. Proper filament storage and moisture control help maintain excellent surface quality, dimensional accuracy and mechanical performance.

• Dry filament before printing
• Store in a sealed container with desiccant
• Print from a dry box whenever possible
• Use moderate print speeds
• Reduce unnecessary retractions
• Direct-drive extruders are recommended for the best print quality

When printed under optimal conditions, VARIOSHORE PEBA 45D/90A NATURAL delivers lightweight, durable and highly resilient parts that are built to perform in demanding engineering, industrial and consumer applications.
