PEBA Filament

PEBA filament from Siraya Tech is where flexibility meets performance. These advanced elastic materials combine the strength of nylon with the bounce and energy return of elastomers—perfect for creators who want their 3D prints to move, flex, and perform like real-world parts. 

Siraya Tech PEBA filaments bring your ideas to life with unmatched rebound, durability, and lightweight precision.

Feel the Power of True Flexibility in Every Print

PEBA filament gives you control over softness, weight, and rebound—so your prints feel alive, not rigid. It’s flexible, strong, and easy to print.

Tunable Elasticity You Can Feel

• Adjust print temperature to fine-tune hardness from soft 70A to firm 95A.
• Create parts that move naturally—ideal for wearables, grips, and cushioning.
• Enjoy consistent elasticity that keeps its shape, even under stress.

Lightweight Strength That Performs

• Up to 50% lighter than standard TPU filaments.
• Perfect for drones, sports gear, and robotics where every gram counts.
• Reduces print weight without losing toughness.

Prints That Snap Back, Again and Again

PEBA filament doesn’t just flex—it rebounds. Every part you print with Siraya Tech PEBA returns to form instantly, ready for action.

High Rebound for Dynamic Designs

• Delivers up to 78% energy return for parts that move with precision.
• Absorbs impact and instantly springs back into shape.
• Great for performance-driven prints like soles, joints, and flexible hinges.

Built for Real-World Durability

• Resistant to oils, greases, and industrial solvents.
• Withstands repeated bending and stress without cracking.
• Keeps performance consistent over time, indoors or outdoors.

Smooth Printing, Stunning Results

PEBA filament is designed for creators who want professional results without the hassle. It prints cleanly and resists jams, even at high speeds.

Easy Printability for Every Maker

• Stiff enough to feed smoothly through direct-drive systems.
• Compatible with most FDM printers (non-AMS recommended for soft grades).
• Produces a soft matte texture that feels premium to the touch.

FAQs on PEBA Filaments

What is PEBA filament?

PEBA filament is a flexible 3D printing material made from a nylon-elastomer copolymer. It combines the strength and chemical resistance of nylon with the elasticity and rebound of rubber-like elastomers.

This makes it ideal for printing functional parts that need to flex, absorb impact, or return to shape under stress.

Is PEBA filament better than TPU?

PEBA filament often outperforms TPU in energy return, weight, and durability. It’s up to 50% lighter and offers higher rebound, meaning parts feel more responsive and dynamic.

PEBA also has better chemical resistance and fatigue performance, making it more reliable for long-term use in demanding applications.

What filament is used to make an airless basketball?

An airless basketball typically uses advanced flexible materials like PEBA filament. Its high rebound and elasticity allow it to mimic the bounce of a traditional inflated ball while maintaining its shape and structure without air.

When printed at 100% infill, PEBA delivers the perfect balance of firmness and flexibility for this type of application.

Is PEBA a polymer?

Yes, PEBA (Polyether Block Amide) is a type of block copolymer made from nylon and elastomer segments.

This unique structure gives it both rigidity and flexibility, allowing it to perform well in applications that require strength, elasticity, and lightweight properties. It’s commonly used in sports gear, robotics, and 3D printing.

Can PEBA filament be used in any printer?

PEBA filament works best in direct-drive FDM printers. It’s not recommended for AMS or Bowden setups due to its softness. With proper temperature and speed settings, it prints smoothly and produces professional-quality flexible parts with a soft matte finish.
