Grok Bots that design, simulate, and 3D-print

MIT's Markus Buehler ran a team of Grok Bots from photos to a physics lab to a Bambu printer. The whole scientific loop, in one night.

Four reference photos in, a hierarchical beam-network simulator out, 47 experiments, a LaTeX report, then STLs sliced on a Bambu H2D. Extra hierarchy is not free toughness: at a fixed material budget, infill steals cross-section from the main veins. First-party, long, and the kind of thread people send to a group chat.
