Flexfill TPU 98A "Signal Red"
Thermoplastic polyurethane with hardness 98 Shore A. A technical semi-flexible filament that offers great mechanical properties such as high tear and tensile strength.
It is characterized by highly reversible deformation, resistance to ozone, oils, greases, and aliphatic alcohols. Wear resistance guarantees the durability of 3D printed products. Great for the printing of continually sliding parts or sealings.
✅ Excellent abrasion resistance and high tensile strength
✅ High elasticity with highly reversible deformation
✅ Great interlayer adhesion for tear strength in all directions
✅ Improved UV stability for long-lasting performance

Daikin's Use of Flexfill TPU
Daikin Device Czech Republic implemented Flexfill TPU from Fillamentum to produce flexible, durable damping tools that reduce noise during marking on assembly lines. This 3D-printed solution lowered noise levels by up to 5.9 dB, enhancing workplace conditions while proving to be a long-term, cost-effective alternative to traditional methods.
Web camera caseby David Řehoř
David Řehoř designed a minimalist and robust case for the Arducam B0205 using Flexfill TPU, ensuring superior protection for the camera. The material’s flexibility and durability make it ideal for electronics casings, absorbing impacts without breaking—a clear advantage over traditional materials like PLA or ABS.
