Looking for good suggestions for suppressor materials. Currently I've just been using PLA+ which has worked, just didn't know if PA6-CF or something infused would work better.

Ditto to everything @kopsis said except the part about annealing. Yes annealing will help. But I’ve had more noticeable strength improvements from moisture treatment over annealing -particularly layer adhesion. The wet sponge in bag method for a few days works quite well.

If you have the time and equipment to do both annealing and moisture treatment, do it.

Annealing isn't for strength, it's for heat tolerance. PET-CF, for example, increases its HDT from 80 °C to around 180 °C after annealing. Nylons see a less dramatic but still significant improvement. For frames and receivers that may be a don't care, but for suppressors it's a big deal.

Oh wow I was not aware. Thanks for sharing. Might have to start annealing my cans.

Different brands have different specs. Siraya Tech documents theirs here: https://siraya.tech/blogs/news/guide-to-annealing-siraya-tech-pet-cf-enhancing-performance-through-heat-treatment

Polymaker has instructions in the "notes" at the end of the Technical Data Sheet.
