PET-G Carbon

Improved hardness and rigidity

Spectrum PET-G Carbon is a modified, PET-G-based filament blended with carbon fibres which contributes to a considerably higher rigidity, hardness and tensile resistance, while retaining low shrinkage and very good adhesion to build platforms typical for the pure PET-G. The 10% addition of carbon fibres enables to obtain matte surfaces of printed items, which greatly improves the aesthetic properties of printed items.

Tip: Due to the essential content of chopped carbon fire, it is recommended to use nozzles with diameters exceeding the standard value of 0.4mm. The presence of carbon fibre may also cause wear of standard nozzles; thus, it is recommended to use hardened steel or ruby nozzles for prolonged application of Spectrum Carbon PET-G.

Material characteristics

  • improved hardness and rigidity as compared to the pure PET-G
  • higher plasticisation temperaturÄ™ as compared to the pure PET-G
  • improved abrasion resistance
  • VICAT 80°C
  • much higher compression resistance as compared to the pure PET-G
  • good mechanical properties
  • high aesthetic, matte surface quality
  • no shrinkage after cooling

Applications

  • items which need to be very rigid and hard while maintaining dimensional accuracy
  • manufacturing of spacer components subject to static compressive loads
  • concept and demo prototyping of designed finished and semi-finished products
  • ornamental parts (aesthetic properties)
  • external structural components which emphasise the product
  • prototyping
