Researchers introduced 3D necroprinting, a biohybrid manufacturing method that repurposes female mosquito proboscises as ultra high resolution 3D printing nozzles. The natural geometry of the proboscis enables line widths down to 20 microns, beating standard industrial dispense tips while withstanding real extrusion pressures. Why it matters. Nature engineered microstructures long before humans did. By using biological components as functional tools, researchers unlock new paths for sustainable
