Thermoplastic Polyurethane Filament

About

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 Explore our specialized TPE filament collection for alternative elastomer options with unique properties. Smooth Printing Performance Without the Usual Headaches Advanced flexible materials shouldn't require advanced degrees to print. Our thermoplastic polyurethane filament is formulated to work reliably with proper setup. Reduced stringing and oozing for cleaner finished parts Compatible with both direct drive and optimized Bowden systems Good layer
