BCN3D PET-G
PET-G
PET-G (Polyethylene terephthalate glycol-modified) is a globally used copolyester, 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.Â
Recomendations
Plastics absorb moisture from the air, it is recommended to keep the PET-G spools in a box or airtight container with desiccant to keep them dry. For a better print quality use an enclosure. PET-G emits low levels of gasses and particles when printed. We recommend printing it in a well-ventilated area.
