3DPrinting
3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices.
The r/functionalprint community is now located at: or !functionalprint@fedia.io
There are CAD communities available at: !cad@lemmy.world or !freecad@lemmy.ml

Just to add...avoid any carbon fiber doped filaments, they are proven weaker and those carbon fiber fragments are dangerous to breathe or touch. It's similar to asbestos.
Yes. If I absolutely must use a fiber filled material, I prefer glass fiber rather than carbon. A fiber fill in your filament reduces shrink and warping and increases rigidity, and makes some tough-to-use polymers more printable such as Nylon. However, the above is correct in that it reduces tensile strength and especially layer adhesion strength, i.e. tensile strength along your Z axis. (Plus, carbon fiber fills basically always limit your color selections to black, black, and black.)
If you need mechanical strength of some type or another, it's almost always a better idea to use a non-filled filament in a more suitable material and work on modifying your printer or getting a better printer that's capable of printing that material. I can do straight polycarbonate in my machine with a pretty high degree of success (other than very small parts, I'm finding) so in all honesty I don't have much use for fiber filled filaments anyway.
