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?
I wouldn’t exactly call it exotic, but I print most things in ABS. It’s just super strong and light weight. I really like Paramount 3D filament. They have really cool colors too. I would like to try something with carbon fiber in it.
I like Paramount 3D for their colors, too. Lots of places have the “basic” colors, but Paramount has a lot of interesting mixes (and names!)
Never printed ABS, but that’s just because I don’t have an enclosure.
ABS is really good if you can manage the warping reasonably well (enclosure, PEI sheet, >90°C bed temps, suitable part geometry).
But the strength and stability at higher temperatures makes it worth the effort, especially for automotive applications. ASA is even UV stable, making it the perfect outdoor material.
