• [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] 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
• [Universal Compatibility, Wide Applications] Compatible with most 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

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.
