Filament Spectrum PET-G HT100

Dimensional stability and high temperature resistance

Spectrum PET-G HT100 is a co-polyester based filament designed for 3D printing in FFF / FDM technology. The material is intended for advanced users, who require excellent durability from printouts working in real conditions.

PET-G HT100 does not contain styrene and is chemical resistant. Excellent dimension stability allows printing with accurate dimensions, which is particularly important for projects consisting of many different elements. One of the biggest advantages of PET-G HT100 is the increased temperature resistance of 100°C.

The higher temperature resistance of Spectrum PET-G HT100 ensures the use of printed elements without fear of deformation. In combination with the additional features such as: dimensional stability, high stiffness and chemical resistance, using PET-G HT100 allows to create fully functional parts.

Tip: It is recommended to print using a heated chamber.

Key features:

  • high temperature resistance (100°C)
  • high dimensional stability
  • high mechanical strenght
  • excellent toughness
  • chemical resistance
  • styrene-free
  • FDA compliance
  • clarity and gloss
  • low odor


  • visual and functional prototyping
  • tooling
  • end-use parts
  • product testing
  • manufacturing aids


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.


– the most precise quality control system on the market

Filament for 3D printers is manufactured by the method of free extrusion, which is one of the most difficult processing techniques by extrusion, due to the particularly large impact of process parameters on product dimensions and material homogenization.

During the production each 1mm of Spectrum Filament is being continuously measured in 2 axis with ±0.8µm accuracy, what allows to obtain a high-quality final product. As a proof of this, Spectrum Filaments has introduced, as one of the few manufacturers in the world, the possibility of presenting online, individually for each manufactured spool:

  • the course of diameter on the entire length of the spool,
  • mean diameter,
  • ovality,
  • standard deviation.

Precise survey guarantees that Spectrum Filaments products meet rigorous market requirements.
