FDM material
PCTG (Glycol-modified Polycyclohexylenedimethylene Terephthalate) 3D Printing
A copolyester like PETG but tougher: several times the impact strength, better clarity, and similar chemical resistance. Prints as easily as PETG. Pick PCTG over PETG for parts that will be dropped, struck, or flexed.

PCTG: common questions
What is PCTG good for?
PCTG is a common choice for impact-resistant housings, clear covers & guards, functional prototypes, containers. A copolyester like PETG but tougher: several times the impact strength, better clarity, and similar chemical resistance. Prints as easily as PETG. Pick PCTG over PETG for parts that will be dropped, struck, or flexed.
How strong and heat-resistant is PCTG?
Printed PCTG parts have a typical tensile strength of 45–55 MPa and heat resistance of ~75 °C. These are typical values for printed parts in the XY direction; strength between layers is lower, so orientation matters for loaded parts.
How big a part can you print in PCTG, and how fast?
Up to 350 × 320 × 325 mm in one piece; larger parts are printed in sections and joined, after a review. Production takes 2-5 business days, and rush service is available.
