    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.

      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.

      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.

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

        It has all of the typical YT influencer bullshit. “Wait 'till then end”, slightly faster than normal speech, reaction memes, overly long descriptions of things in order to pad in more time for ads, flat out ads in the middle, etc.

        My old person trait is that I’d rather spend five minutes reading an article than 15 minutes watching a video.
