FDM material
Polyethylene Terephthalate Glycol 3D Printing
Strong, durable and chemically resistant, for functional parts that need toughness without ABS warping. Some PETG resins meet FDA food-contact rules as raw material, but a printed part is not food-safe: its layer lines trap bacteria.

PETG: common questions
What is PETG good for?
PETG is a common choice for food packaging prototypes, medical device prototypes, outdoor parts, chemical-resistant parts. Strong, durable and chemically resistant, for functional parts that need toughness without ABS warping. Some PETG resins meet FDA food-contact rules as raw material, but a printed part is not food-safe: its layer lines trap bacteria.
How strong and heat-resistant is PETG?
Printed PETG parts have a typical tensile strength of 50–55 MPa and heat resistance of ~80 °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 PETG, 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.
