Love the filament guide you recently published. Interesting to see direct comparisons in that way along with the relative differences between the top contenders. Tensile strength, creep and impact resistance, and layer adhesion are all important metrics.

As the title suggests, I'm very interested in similar analysis regarding resistance to heat; particularly with the PET-CF from Bambu. In your paper you mentioned one of the large downsides to PA612-CF was its annealing requirement. PET-CF without annealing obviously performed well mechanically, but I've read elsewhere that much of its heat tolerance comes after annealing. In its data sheet from Bambu for example, it's clear all of their specs were determined using annealed samples.

I imagine that annealing generally serves to improve the performance of most mechanical characteristics, but it seems important to know how much so in this specific aspect since it's one of the big selling points of PET-CF. Do you have any data for its heat resistance before annealing?
