New 3D-Printing Technique: A Game Changer for Medical Testing Devices

Microfluidic devices are compact testing tools made up of tiny channels carved on a chip, which allow biomedical researchers to test the properties of liquids, particles, and cells at a microscale. They are crucial to drug development, diagnostic testing, and medical research in areas such as cancer, diabetes and now COVID-19. However, the production of these devices is very labor intensive, with minute channels and wells that often need to be manually etched or molded into a transparent resin chip for testing. While 3D printing has offered many advantages for biomedical device manufacturing, its techniques were previously not sensitive enough to build layers with the minute detail required for microfluidic devices. Until now.
