I heard it will eat a brass nozzle if it has some age to it. Eh, I could care less except that it does produce some cool looking objects that normal PLA cant replicate.
Comment on 3D Printing’s Biggest Scam Is Even Worse Than We Thought! (PLA-CF)
unpossum@sh.itjust.works 2 weeks ago
Summary:
This video critically examines the popular perception of PLA carbon fiber (PLA CF) reinforced 3D printing filament, arguing that it is an even bigger scam than previously thought. By conducting bending tests, microstructural analysis, and CT imaging, the creator demonstrates that PLA CF does not improve mechanical strength, stiffness, or impact resistance compared to regular PLA. Instead, carbon fibers disrupt layer bonding, create voids, and lead to stress concentration, ultimately weakening printed parts.

Hence why most printers don’t come with brass nozzles anymore. The majority come standard with hardened steel.

It’s more that stainless steel is cheaper than brass these days.

Honestly whether it’s PLA or not it seems incredibly foolish to print with filament impregnated with carbon fibers. Like, “hey this lead tastes sweet” level of foolish.

Fiber impregnated filament is actually really great if the material is prone to warping. It stabilizes the filament and reduces warping cause by shrinkage as the filament cools.
That’s really the only thing it’s good for. So unless you’re printing PLA crazy fast, it’s useless.
