Thermoplastic polyurethane filament brings rubber-like flexibility to your 3D printer, letting you create parts that bend, stretch, and bounce back without breaking. At Siraya Tech, our TPU collection is engineered for makers who need more than rigid plastics can offer—phone cases that actually protect, gaskets that seal properly, and wearables that move with you. With improved flow characteristics and consistent quality, these materials deliver the flexibility you need without the printing frustrations.
Thermoplastic Polyurethane Filament Engineered for Reliable Flexibility
When your project needs to bend without breaking, thermoplastic polyurethane filament provides the perfect balance of elasticity and printability that actually works.
- Shore hardness options from 85A to 95A for varying flexibility levels
- Excellent elasticity returns to original shape after stretching
- Superior tear resistance prevents splitting during use
- Consistent diameter tolerance eliminates feed problems
- Optimized flow properties reduce jamming and under-extrusion
Outstanding Durability for Real-World Applications
TPU filament isn't just flexible—it's built to handle repeated stress and daily use without losing its properties or breaking down over time.
- High abrasion resistance for long-lasting performance
- Chemical resistance to oils, solvents, and cleaning products
- Temperature stability from -40°C to 80°C for indoor and outdoor use
- UV-resistant formulations prevent degradation from sunlight
- Maintains flexibility through thousands of flex cycles

FAQs About Thermoplastic Polyurethane Filament
What is TPU filament good for?
TPU filament excels at creating flexible, rubber-like parts including phone cases, gaskets, toys, and wearables. It's perfect for applications requiring shock absorption, sealing properties, or repeated flexing. The material combines durability with elasticity, making it ideal for functional parts that need to bend without breaking.
What is Thermoplastic Polyurethane used for?
Thermoplastic polyurethane is used across many industries for flexible components like automotive seals, medical devices, footwear soles, and protective cases. In 3D printing, it enables creation of gaskets, phone accessories, prosthetics, toys, and any application requiring rubber-like properties with the convenience of thermoplastic processing.
Is TPU hard or flexible?
TPU is flexible, ranging from semi-rigid to very soft depending on its shore hardness rating. Most 3D printing TPU falls between 85A-95A shore hardness, providing rubber-like flexibility while maintaining enough structure for reliable printing. Lower numbers indicate greater flexibility and softer feel.
Is TPU better than PLA?
TPU and PLA serve different purposes—TPU is flexible while PLA is rigid. TPU is better for applications requiring elasticity, impact absorption, or repeated flexing. PLA is easier to print and better for decorative items or rigid functional parts. Choose based on whether you need flexibility or structural rigidity.
