Been learning about Nylon strengths and weaknesses. I know moisture isn’t as big of a deal as people make it out to be but was hoping for some advice/understanding on which type of nylon cf might be best for me.
So pa6 is strong as hell…but once it’s saturated it loses a ton of its initial strength.
To my understanding PA612CF15 retains way more strength when saturated.
This is with and without annealing. Either way you’re losing strength. So my question is. If you lived in a relatively humid environment… are you going PA6CF20? PA612CF15? PA612CF10 or PA12Cf?


It has better elongation at break when wet than dry. Gonna have to define “stronger” a bit more rigidly (heh) if you wanna make clear comparisons.
It sounds like aluminum when you flick it right off the print bed, but it shouldn’t if you intend to build a Glock out of it.
