The Next-Gen TPU Alternative: PEBA 90A flexible filament is engineered as the premium replacement for TPU. Combining nylon-level toughness with elastomer flexibility, it achieves the perfect balance of strength and softness for advanced 3D printing projects. 

20% Lighter, Print Smarter, RoHS Compliant: With a density 20% lower than TPU, PEBA enables ultra-lightweight prints without compromising durability, ideal for drones, robotics, wearables, and performance parts where every gram matters

78% High Rebound Performance: Delivering up to 78% energy return, over 30% higher than TPU, PEBA ensures faster bounce-back, superior elasticity, and long-lasting resilience. Perfect for sports gear, cushioning parts, and functional prototypes

2X Faster Printing, Adjustable Flexibility: Engineered for efficiency, PEBA prints up to 2X faster than TPU with higher volume flow. Print settings allow you to fine-tune hardness and flexibility, adapting to applications from soft insoles to structural components

Support Multi-Color Multi-Material 3D Printer: Compatible with most Multi-color and multi-material FDM 3D printers using 1.75mm filament and dual-gear extruders. Widely applicable for sports equipment, medical devices, robotics joints, cushioning solutions, and creative prototyping

What PEBA Is & Its Performance

PEBA is a block copolymer combining rigid nylon (amide) blocks and flexible ether blocks, balancing strength with elasticity. In many metrics, PEBA can surpass standard TPU: rebound, lightweight, chemical resistance, low-temperature performance, and fatigue durability.

For example, Fillamentum’s Flexfill PEBA 90A lists a printing temperature of 225–245 °C, low density, and flexibility at –60 °C.

SainSmart’s Rebound PEBA 95A markets a rebound rate of 78% and being 15–20% lighter than TPU.

PEBA Filament Flexible High Rebound, 1.75mm 90A 1KG, Super TPU with 78% High Rebound, 20% Lighter & 2X Faster Printing, Nylon-Based Strength, Adjustable Flexibility

Step into the next generation of flexible 3D printing with PEBA 90A filament — a breakthrough material that combines nylon’s toughness with polyether’s flexibility. Compared to traditional TPU, PEBA offers 15–20% lower density, 2× faster print speed, and superior rebound elasticity (70–85%), giving professional makers the freedom to create lighter, stronger, and more efficient prints.

Whether you’re prototyping sports gear, engineering functional parts, or pushing the limits of soft robotics, PEBA ensures consistent strength, adjustable via infill, while maintaining unmatched softness and durability.

Compatible with most FDM 3D printing machines.

FAQs

PEBA vs TPU / TPE / ABS / PLA: Strengths & Trade-offs

  • Compared with TPU: TPU is mature, easy, cheaper; PEBA offers potential wins in rebound, low-temp behavior, weight, and chemical stability, but its printing difficulty is higher.
  • Compared with TPE: TPE is a broad genre of elastic materials; PEBA is in the higher-performance niche.
  • Compared with ABS / PLA: ABS and PLA are rigid / structural / prototyping materials; PEBA is for flexible / functional parts. In many designs, they complement rather than compete.

Use Cases & Application Areas

  • Cushioning / elastic parts / springs / mounts
  • Sporting goods / shoe soles / protective gear
  • Robotics / grippers / soft-robot structures
  • Automotive / drones / flexible components / seals
  • Low-temperature or extreme environment flexible parts
