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?
It's all in the data sheets. PA6-CF has significantly better impact strength - especially when it's had a chance to absorb some moisture. That goes hand in hand with PPA being significantly stiffer.
PPA-CF has a little better tensile strength and layer adhesion, but they're both good enough (assuming you can print hot enough) that the difference doesn't matter much. Last but not least, PPA-CF has a little higher heat deflection temperature.
