About PET-G

Polyethylene terephthalate glycol (you see why we call it PET-G now) is a high performance material, best used only when your application demands better UV and heat resistance than our Recycled PLA and Tough PLA options can provide. PET-G has good interlayer bonding, and as well as classic white and black colours, comes in a fluorescent yellow option that is sure to catch the eye.

The main downside of PET-G is its tendency towards 'stringing' which leaves some small, wispy 'hairs' on the surface of some parts. These can easily be removed by sanding, but other materials still have a better surface finish.
