A polyester engineering material for stable functional parts where processing is selected to suit the job.
PET
What it’s for
Functional prototypes, Brackets and mounts, Replacement parts, Jigs and fixtures, Test fixtures, Bench tooling, Short-run production, Chemical exposure. We choose the final route against the geometry and service environment, not from the material name alone.
Key characteristics
- 01Its semi-crystalline polyester structure can balance stiffness and chemical resistance.
- 02That supports durable utility components.
- 03Its crystallisation behaviour needs a material-specific print plan.
- 04Use it for functional housings, guides, and production-oriented parts.
In our shop
We source PET for a defined job rather than treating it as interchangeable with PETG.
Once the service requirement is clear, we can decide whether its processing trade-offs are worthwhile.

Design notes
- Bring the expected chemical and temperature exposure to review.
- Use ribs instead of solid sections where stiffness is the objective.
Technical values appear only after we approve a datasheet for the exact spool in use. If a specific property determines the job, tell us and we will discuss the material route.
