It really depends on what you're building. For controlled environments that's fine, but unfortunately I'm not building for controlled environments, and tend to do quite extreme things with parts. I need them to be subjectable to force and reasonable amounts of heat. There is no way around it in my applications.

Point is PETG works, sometimes I need to go to CF-Nylon, I'm just looking for something that's as good mechanically and can be recyclable. I wonder if the plastics in the article would work.
