Really enjoy how PAHT-CF prints
(forum.guncadindex.com)
I know everyone has their "go-to" filament(s) for various parts. For me with 2A, it is usually PLA+, PAHT-CF, and PPA-CF. What I have really enjoyed about this filament is how easy the supports were to dial in. They pop right off and leave a pretty good looking contact point.
My Urutau's bolt and upper receiver, both in PLA+, developed a crack recently and figured I might as well reprint the handgaurd while I was at it.
Ive been telling people about elegoo's paht-cf for a few months now. Another redditor put me on to it and I absolutely loved the way it printed using bambu's paht-cf profile. Its a bargain too for a pa612 blend. That being said I like trying all different types of brands and types of filaments period. Im printing with some sun-lu pa6-cf right now in my Centauri Carbon and the print looks amazing so far. I plan to anneal so Im curious how it will do there. I have my k2 plus printing some Creality ppa-cf at the moment as well. Also printing gorgeously. I had some issues with ppa-cf and creep but I didnt anneal it either so Im palnning on annealing the ppa-cf as well.
I tried a roll of Creality PPA-CF and had issues with it breaking during the last 200g or so. Three times it snapped coming off the spool in the dryer. It did print super good, though for the first 800g. I chalked it up to maybe needing to dry it more, but at its price I just stick with Siraya's core black.
