PET

PET (Polyethylene Terephthalate) is a durable thermoplastic widely used in FDM 3D printing for functional and semi-structural parts. It combines good mechanical strength with chemical resistance and low moisture absorption compared to many other common filaments. PET prints typically show strong layer bonding, reducing the risk of delamination under load. The material offers good impact resistance and maintains dimensional stability across moderate temperature ranges. Its surface finish is usually smooth with a slight sheen, depending on print settings. PET is less brittle than PLA and generally easier to print than more advanced engineering polymers, making it a practical option for brackets, housings, mechanical fixtures, and general-purpose functional components.

Available finishes

Each finish can be combined with the available colors at checkout.

Standard

9 colors

As-printed PET parts feature a smooth, slightly glossy surface with visible layer lines typical of the FDM process. The material provides strong layer adhesion, good toughness, and reliable dimensional stability without additional post-processing.

Sanded

9 colors

Sanded PET parts offer a smoother, more uniform surface finish compared to as-printed components.
