# PET

## Material Info

### About
PET is a high-quality 3D printing filament known for its excellent strength, durability, and ability to produce watertight products. It offers outstanding print results with minimal warping, making it ideal for functional prototypes, packaging, and end-use parts. With its reliable performance and strong mechanical properties, PET is a versatile choice for a wide range of applications. A wide variety of colors is available and can be printed at request through [our Sales team.](/content/business/additive-manufacturing#contactsales/index.html)

Parts are oriented by our team to balance strength, surface finish, and minimal supports. Final orientation is chosen for the best overall result.
