When it comes to printing flexible, durable, and functional parts, standard TPU has long been the go-to choice. But what if your project requires something lighter, bouncier, and more resilient to extreme temperatures?

Enter the latest innovation from eSUN: the PEBA-85A Filament

Designed for makers, engineers, and designers who demand professional-grade performance, PEBA-85A is a high-performance flexible 3D printing filament that pushes the boundaries of what desktop 3D printers can achieve.

Let’s dive into what makes PEBA-85A the next must-have material for your 3D printing arsenal.

What Makes eSUN PEBA-85A Stand Out?

1.Maximum Rebound Rate Reaches 70%

If you are printing parts that require energy return—such as shoe midsoles, bouncy balls, or shock absorbers—resilience is key. Compared to traditional TPU filaments, parts printed with PEBA-85A feature significantly higher resilience. In standard drop tests, PEBA achieves a maximum rebound rate of up to 70%, crushing TPU's average of 52%.

2. Ultra-Lightweight (15~20% Lighter than TPU)

Weight reduction is critical in industries like sports, aerospace, and wearable tech. PEBA-85A boasts a density as low as 1.05g/cm³. This means it is 15% to 20% lighter than standard TPU (which typically sits around 1.2g/cm³). You can significantly reduce the weight of your printed parts while maintaining excellent structural strength, enabling true lightweight design.

3. Resists Low-Temperature Embrittlement

Many flexible materials become stiff and brittle when exposed to freezing temperatures. PEBA-85A defies this limitation. It maintains its outstanding flexibility, rebound, and impact resistance across a wide temperature adaptation range from -40°C to 90°C. Whether used in winter sports gear or high-heat environments, PEBA stays reliable.

4. Unmatched Resistance to Repeated Bending

Durability is non-negotiable for wearable parts. PEBA-85A offers excellent fatigue resistance. It can withstand intense pressure and repeated bending without permanent deformation or performance degradation, making it perfect for functional prototypes and end-use products.

5. Smoother Printing, More Reliable Performance

Flexible filaments can sometimes be tricky to print, but eSUN has optimized PEBA-85A for a stable printing process. It features low shrinkage, effectively resisting warping. Furthermore, it supports a maximum volumetric flow rate of up to 9mm³/s, enabling higher printing speeds and smoother extrusion, significantly reducing print failure rates.

Wide Range of Applications: Unlocking Infinite Possibilities

Thanks to its unique physical properties, eSUN PEBA-85A is opening doors to applications that were previously difficult to achieve with standard FDM printing:

• 👟 High-End Footwear Materials: Provides a comfortable rebound and lightweight feel, making it the ideal choice for professional midsoles and insoles in sports shoes.
• 🚴 Sports Equipment: Perfect for protective gear and cushioning components. It's strong, durable, and ready for professional performance.
• 🏥 Medical Equipment: Offers soft support that is safe and eco-friendly. Highly suitable for custom orthopedic braces and rehabilitation accessories.
• ⌚ Smart Wearables: Skin-friendly and fatigue-resistant, adaptable to various wearable structures for both daily and extreme use.
• ⚙️ Industrial Components: Ideal for shock absorption, cushioning, and flexible connection structures in complex operating conditions.

(Note: For the transparent color products in the PEBA series, trace black specks on some extruded lines are a normal occurrence. They do not affect the final usage or structural integrity, so you can purchase and print with absolute confidence.)
