BigRep’s PETG is an environmentally friendly high-performance 3D printing material. Similar to familiar recyclable PET materials, PETG is made to be compatible with the thermal extrusion process. The material offers high durability and impact resistance with stunning transparency and a high-gloss finish.

PETG prints well in open environments and is an excellent, affordable alternative to engineering-grade materials for many high-stress or impact applications. It’s an excellent choice for aesthetic features. It’s weather and UV resistant, making it an excellent choice for outdoor applications.

The material is easy to print, making it the choice for additive novices.


  • High strength
  • High gloss finish
  • Translucent
  • Weather and UV resistant
  • Minimal warping


BigRep’s PETG is a high-quality offering of the versatile material. Even though it prints at a higher temperature, it’s quite easy to print with. I experienced no warping or peeling on printed parts and every object came out looking good, though some had slight stringing that was wiped off with minimal effort; adjusting retraction a bit would likely resolve the issue completely. When it comes to overhangs, this is as good as it gets. Being able to print steep overhangs allows users to print more complex geometries and forego the use of support material, saving time and resources. The high heat deflection temperature opens the door to many functional applications, and the strong layer adhesion extends its functionality even further. And it makes a fantastic lightsaber. What else do you need?
