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?
You may want to look into Middleton's GAP: https://guncadindex.com/detail/Grandmas-Apple-Pie-GAP-v15:6
You buy the metal buffer tower from a parts vendor and print the lower. Comes with an ambi bolt catch and dovetails, as Middleton is wont to do. It's not one-piece, but it slims the lower significantly since it takes force from a more manageable angle.
