15 m Sample | 1.75 mm | Flexfill TPU 98A

15 m Sample of Flexfill TPU 98A in a sachet.

Thermoplastic polyurethane with hardness 98 Shore A. A technical semi-flexible filament that offers great mechanical properties such as high tear and tensile strength.

Highly reversible deformation, resistance to ozone, oils, and greases. Wear performance guarantees the durability of 3D printed products. Great for the printing of continually sliding parts or sealings.


  • Can be used for the final surface treatment
  • Great interlayer adhesion ensuring tear strength in all the directions
  • Excellent abrasion resistance
  • High tensile strength
  • Printing with 100% infill ensures a tough object
  • Improved UV stability
  • Good rebound resilience
  • High elasticity with highly reversible deformation
  • Safe to use in electrical and electronic equipment
  • Semi-flexible
  • Low warping and stringing
  • BPA-free and styrene-free
  • Recyclable
