McGill University scientists turned a mosquito's proboscis into one of the smallest 3D printing tools ever created. By integrating the mosquito’s microscopic needle coated with photopolymer resin into a 3D printer, they achieved a printing resolution of 18 to 28 microns—twice as precise as some advanced printers. This innovation offers groundbreaking potential for medical applications, including the precise printing of microblood vessels, biosensors, and complex living tissues. Leveraging a natural biological mechanism refined over millions of years, this approach could drastically reduce costs and improve 3D printing accuracy in biotechnology. The advancement showcases how biomimicry can accelerate technological progress by using nature’s existing solutions to solve engineering challenges. From Ivan Geoffrey-Youtube
