TPU S-Flex 98A filament Spectrum Filaments 1,75 mm / 0,25 kg

S-Flex 98A filament Spectrum 0.25 kg

TPU S-Flex 98A is a filament based on thermoplastic polyester polyurethane. The 3D printing process with the S-Flex 98A is relatively easy and trouble-free. In addition, the excellent adhesion of the first layer of the printed model to the work surface allows you to get perfect 3D printing, regardless of the material from which this surface is made: glass, steel, plastic or other material.

Low shrinkage during processing and high flexibility significantly reduce the risk of so-called folding of the edges of manufactured parts. Shore 98A hardness classifies the Spectrum S-Flex 98A as a solid elastomer. This feature in terms of the 3D printing process reduces the risk of thread deformation in the thread feed system to the print head. This allows you to print at slightly higher speeds than other elastomers.

Parts made of Spectrum S-Flex 98A are characterized by very high resistance to hydrolysis (a kind of destruction 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 impact surfaces (bumpers, sharp edges), sealing and protective elements with high chemical resistance, as well as thermal insulators.

S-Flex 98A features

  • High resistance to hydrolysis.
  • Up to 510% elongation at break.
  • Shore hardness - 98A.
  • High tensile strength and tear resistance.
  • Low shrinkage.
  • Resistance to many common industrial oils and chemicals.
  • Reduced the number of lines when the printer is not working.

TPU S-Flex 98A application

  • Manufacturing of seals with high chemical resistance.
  • Manufacturing of products to be used as energy adsorbents.
  • Functional parts.
  • All kinds of bumpers, vibration dampers, guides, protective cases, clamping parts.
  • Sleeves, hinges, bumpers and flexible gaskets.
  • Sealing parts with increased rigidity.
  • Spring-cushioning elements for use in mechanical engineering and modeling.
  • Flexible tapes with high strength.
  • Covers and housings for various devices.

Verify quality of 3D plastic thread 

Spectrum Filaments is the only company in Poland and one of the few in the world that has a tool for testing purchased filaments. VERIFY YOUR SPOOL is the most accurate quality control system on the market, ensuring that Spectrum Filaments products meet his stringent requirements.

Filament for 3D printers is produced by free extrusion, which is one of the most difficult extrusion processing technologies, due to the particularly significant influence of process parameters on product dimensions and material homogenization. During the manufacturing process, each 1mm of Spectrum Filaments is continuously measured in 2 axes with an accuracy of ±0.8 µm, resulting in a quality end product. To prove this, Spectrum Filaments, as one of the few manufacturers in the world, has introduced the possibility of an online presentation, individually for each coil produced:

  • diameter travel along the entire length of the coil;
  • average diameter;
  • ovality;
  • standard deviation.
