How Everything Is Made on Instagram: "Engineers turned one of nature’s most precise biological tools into a microscopic 3D-printing system. 🦟🔬 They studied the structure of a mosquito’s proboscis — the ultra-thin feeding needle it uses to pierce skin with incredible accuracy. This biological design is strong, flexible, and able to channel fluids through openings far smaller than a human hair. By replicating that architecture, researchers built a microscopic 3D-printing nozzle capable of creati
