Today started as a straightforward round of my standard material testing on 3D-Fuel PET-CF, but that did not last long.
Once I got into the HDT testing, this turned into a full rabbit hole of different temperatures, annealed samples, unannealed samples, and a result that was interesting enough that I had to stop and dig deeper.
This video covers the standard PET-CF testing, the heat testing, the annealing curve, the failures, and the part of the data that made me start asking more questions.
No marketing fluff. Just testing, results, and what actually happened.

About This Test
This testing includes my normal material comparison workflow along with additional HDT-style heat testing using different thermal conditions.
The PET-CF samples were tested in both annealed and unannealed states to look at how the material behaves under heat, and whether annealing meaningfully changes the outcome.
As always, my testing is meant to be practical, comparative, and repeatable inside my own test workflow. It is not a replacement for manufacturer data sheets or certified lab testing, but it does show how these materials behave under the same TLAR-style conditions I use across my material database.
