I have some Fiberology PA12+CF15 blend (link) from a long time ago and recently got around to using it. I am amazed to say the least! It prints easier than PETG, even without an enclosure. Only downside is that it is much more expensive per kg, although it is lower density so I don’t seem to be going through it as quickly as other filaments.
I recently purchased some PC Blend with CF from Prusa as well. I haven’t gotten to print it yet, but I’ve heard very good things about it, too.
What less common filaments do you fine folks like using?
Yup, I like that stuff, too. I just printed some shelf brackets in Hatchbox wood PLA. Lots of stringing but they look pretty sweet after post processing.
What size nozzle do you use with it? I’ve seen lots of suggestions for 0.6mm and up, but I’ve been able to print with a 0.4mm without clogs.
I use 0.4mm too as I am usually too lazy to change the nozzle. Only printed a bunch of keyboard cases up to now but they came out great.
