PET-G HT100 filament Spectrum Filaments 1,75 mm / 1,0 kg

Heat resistant PETG HT100 for 3D printer

Heat resistant PETG HT100 for 3D printing FDM models where dimensional stability and resistance to high temperatures are important.

This material is based on copolyester, designed for advanced users who need excellent strength from printed parts that work in real conditions.

PETG HT100 does not contain styrene and is chemically resistant. Excellent dimensional stability allows you to print with accurate dimensions, which is especially important for projects consisting of many different elements. One of its biggest advantages is increased resistance to temperatures up to 100 °C.

The higher heat resistance of the Spectrum PETG HT100 ensures the use of printed elements without the risk of deformation. Combined with additional features such as dimensional stability, high rigidity and chemical resistance, the use of PET-G HT100 allows you to create fully functional parts.

Tip: It is recommended that you print with a heated camera.

Heat resistant PETG for 3D printing strength of printed parts


A 1.0 kg filament is wound on a transparent spool, which contains information about the type of material, diameter, color and recommended printing temperature. Each coil is packed in a vacuum with a dehumidifier. All in the original Spectrum Filaments foil cardboard.

Coil dimensions

  • Outer diameter - 200 mm.
  • Width - 67 mm.
  • Inner diameter - 52 mm.
  • Weight of empty coil - ± 250 g.

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.
