Innovative approaches in bio-inspired engineering continue to push boundaries. A recent breakthrough involves transforming a mosquito’s proboscis into a highly precise nozzle for 3D printing. This development offers a new perspective on integrating natural microstructures into advanced manufacturing tools.

Led by Professor Changhong Cao at McGill University, the team explored various biological structures—such as insect stingers and snake fangs—to find the ideal natural tip for their “necroprinting” technique. After extensive analysis, they selected the female mosquito’s proboscis, renowned for its ability to pierce and deliver fluids efficiently. Remarkably, it proved effective as a steady-flow nozzle suitable for high-precision 3D printing.

Biological Inspiration Meets Modern Technology

According to Cao, most natural fluid delivery systems, like insect stingers or snake fangs, are optimized for rapid injections rather than continuous flow, which is essential for 3D printing. The mosquito’s proboscis, however, offers a unique combination of sharpness, flexibility, and controlled fluid release, making it an ideal candidate.

Experts highlight this innovation as a promising fusion of biology and engineering, opening new avenues for microfabrication and medical applications. This approach exemplifies how nature’s evolved mechanisms can revolutionize manufacturing processes, leading to more precise and sustainable technologies.
