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?
Maybe more in the “less mainstream” category rather than exotic, but I love ColorFabb varioshore TPU. I really like the texture and slight squishiness it gets at 220°, also floats. I also use it in lots of places where I don’t really need a semi flexible, it’s surprisingly handy.
For exotics, as in “need to scour the internet to find”, eSun ePC is a personal favorite. Prints very cleanly at 270°, looks great, very little warp, super durable. Nasty fumes, though.
Edit: a lot easier to get hold of now, must have been a production hiccup last time I needed some.
