  • …I don’t understand your comment, I think. Is pointing out historical facts ad hominem? My (small) point was that I’m not certain that the sudden prosperity that some workers in the US enjoyed was entirely sustainable. That said, the development since the seventies or so has definitely gone hard in the other direction. I’m not competent to comment on the causes, but successful deunionization, destruction of the educational system, and overseas outsourcing of everything productive are probably in there somewhere.







  • 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.
