If the part doesn't have to last long or is subjected to smaller forces and the robot is kept in a controlled place PLA is fine. We used them it to make parts for robotics competitions in college.

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.

Sample size fallacy right here. Just because it's useless to you doesn't mean it's useless. Plenty are doing fine with PLA.
