PET-G BCN3D Filaments

Heat resistant, Stiff, High strength



PET-G (Polyethylene terephthalate glycol-modified) is a globally used co-polyester, from plastic water bottles to cloth fibers and it is 100% recyclable.

As a technical material, PET-G provides good mechanical properties and improved chemical and thermal behaviours than PLA but with similar ease of use.


  • Parts in contact with salts, acids and alkalis
  • Models requiring high geometrical and dimensional accuracy
  • Functional prototypes and mechanical parts


  • Outstanding chemical resistance
  • Great dimensional stability and toughness
  • Good glossy surface quality
  • Good abrasion resistance
  • High humidity resistance
  • Withstand operating temperatures up to 70°C
  • Low rate of ultrafine particles (UFP) and volatile organic compounds (VOC)
  • Compatible with PVA supports

Bed adhesion:

To ensure good bed adhesion use Magigoo.


Plastics absorb moisture from the air. For long periods of time without printing, it is recommended to keep the PET-G spools in a box or airtight container with desiccant to keep them dry.
PET-G emits low levels of gasses and particles when printed. We recommend printing it in a well-ventilated area to ensure a healthy environment.
For a better print quality use an enclosure.
