Filament Spectrum S-Flex 98A

Flexibility with very good impact strength and thermal insulation

Spectrum S-Flex 98A is a filament based on a thermoplastic polyether polyurethane. In the area of additive manufacturing, S-Flex 98A is a material characterized by a relatively easy and failure-free 3D printing process. An additional advantage that allows obtaining a perfect printout is very good adhesion of the first layer of the printed part to the working space, regardless of whether it is made of glass, steel, plastic or other material.

Low processing shrinkage and high flexibility significantly reduce the risk of the so-called curling up of the edges of manufactured parts. The distinguishing feature in the filament name - 98A – relates to the hardness of the material on the Shore scale and classifies Spectrum S-Flex 98A in the category of hard elastomers. This property - from the point of view of the 3D printing process - reduces the risk of filament deformation in the insertion system leading the material to the printing head. This enables a slightly faster printing compared to other, more compliant elastomers.

Parts made of Spectrum S-Flex 98A are characterized by very high resistance to hydrolysis (a kind of degradation caused by the presence of water), good recyclability and very good resistance to dynamic forces. Thanks to these properties, it is possible to 3D print parts that protect surfaces exposed to impact (bumpers, sharp edge guards), sealing and protective elements with high chemical resistance, as well as thermal insulators.

Key features:

  • high resistance to hydrolysis
  • up to 510% elongation at break
  • Shore-A hardness of 98
  • high tensile and tear resistance
  • low shrinkage
  • resistance to many common industrial oils and chemicals
  • reduced stringing while the printer is running idle


  • manufacturing of seals with a high chemical resistance
  • production of items, which has to be used as energy adsorbents
  • functional parts
  • all kinds of bumpers, vibration dampers
  • guides
  • protective cases
  • snap-fit parts
  • sleeves
  • hinges
  • bumpers and flexible spacers,
  • sealing parts with increased stiffness,
  • spring-damping elements for use in machine production and modeling,
  • flexible bands with high strength,
  • covers and housings for various devices,


Filament is reeled on the neat, transparent spool. Each spool contains information on the type of material, diameter and recommended printing temperature. Filament is vacuum-packed with a moisture absorber. Whole product packed in the original, folied Spectrum Filaments packaging.
