Researchers have transformed female mosquito feeding tubes into ultra-high-resolution 3D-printing nozzles.
The approach allows printers to lay down material with line widths as small as 20 microns — slightly smaller than a white blood cell.
The result pushes current 3D-printing limits. The team named the technique “3D necroprinting.”
The process uses a non-living biological structure directly as a functional manufacturing tool. Unlike conventional nozzles, the mosquito proboscis evolved for efficient penetration and fluid transport.
Its natural geometry reduces clogging and pressure buildup, making it well-suited for controlled material deposition.
