15 m Sample | 1.75 mm | Flexfill PEBA 90A "Natural"

This type of Flexfill is based on polyether-block-amide (PEBA), which was specially developed for processing by 3D printing. Although it is flexible with hardness 90 Shore A, it exhibits different thermal, mechanical, and chemical behavior from other Flexfill filaments (TPU, TPE)! 

  • Excellent mechanical properties
  • Flexible even at low temperatures
  • High reversible deformation
  • Rebound resilience preserved also at low temperature (down to -60°C)
  • Great chemical resistance, resistance to car fluids (gas, diesel, oil, ...)
  • Resistant to cyclic loading without obvious damage
  • High energy return, low hysteresis
  • Tear resistance
  • Low density, lightness
  • Recyclable, BPA free, low fumes released
Working temperature: 225–245 °C
Heated bed: 70–90 °C
Available diameters: 1.75 mm
Diameter tolerance: +/- 0.10 mm 
Weight: 500 g of filament (+ 230 g spool)
