Glycol modified polyethylene terephthalate (PET-G) is a polyester with good toughness and chemical resistance. 3D printed PET-G exhibits good layer adhesion and can be used to produce all kinds of products which include end use parts, prototypes, jigs, and fixtures. Clariant improves the heat stability and resistance to thermal processes using appropriately selected additives such as Hostanox® P-EPQ® and Hostavin® ARO 8.

  • Strong and tough engineering thermoplastic
  • Transparent
  • Good impact strength
  • Good chemical resistance
  • Reduced thermo-oxidative degradation
  • Minimized undesired yellowing due to ultraviolet light

  • Prototypes
  • Tools, jigs, fixtures
  • Containers / packaging
  • Mechanical and technical application parts
*Subject to detailed product specifications.

  • Print Temperature = 240-260°C
  • Print Speed = 30-60 mm/s
  • Bed Adhesion = a generous uniform layer of a PVP based glue, use of a commercial adhesion sheet or commercial bed adhesive
  • Bed Temperature = ideally heated up to 70-80°C
  • Fan Settings = medium to high

Note: parameters are dependent on printer used; Clariant tests were performed on an Ultimaker 3 extended and an Ultimaker S5.
