A Nozzle to Improve 3D Printing

A team of Johns Hopkins civil and systems engineers has developed a new 3D printing technique that uses a nozzle that can change its size and shape during the printing process, overcoming the speed-resolution tradeoff inherent to traditional 3D printers with fixed-nozzle diameters. Watch this video to learn more about the new nozzle: AN3DP.

“Traditional 3D printers use fixed nozzles, which limit either resolution or speed. Smaller nozzles improve resolution but slow down printing, while larger nozzles increase speed but reduce detail. AN3DP’s design overcomes this by adjusting to the specific requirements of each feature being printed, allowing for both high resolution and faster printing,” said corresponding author Jochen Mueller .
