PPA-CF vs PA6-CF? (forum.guncadindex.com)

PPA-CF vs PA6-CF?

Does anyone have experience printing PPA-CF and PA6-CF? I had read that "PPA-CF is 48% stronger" than PA6 if you get good layer adhesion, but I'm seeing conflicting info regarding impact resistance. Anyone have input who's printed and used both?

I have a Septree dehydrator that I got off Amazon. It's the smaller white one that's like 70 bucks and then I dry at 190F for 48hrs. Once it's dry I take it out of the dehydrator and put it in my Sunlu S4 and print from it at 70c. Or you can get a Lazy Susan for the dehydrator and drill a hole through the side and tap a Ptfe fitting in it so that you can run a Ptfe tube straight from the dehydrator. Cerakote works perfect for keeping moisture out of the print and also keeps the tiny CF/GF pieces from getting embedded into your hands.
