BOULDER — University of Colorado Boulder engineers have developed a 3D printing technique that allows for localized control of an object’s firmness, opening up new biomedical avenues that could one day include artificial arteries and organ tissue. The study, which was recently published in the journal Nature Communications , outlines a layer-by-layer printing method that features fine-grain, programmable control over rigidity, allowing researchers to mimic the complex geometry of blood vessels that are highly structured and yet must remain pliable. CU said the findings could one day lead to better, more personalized treatments for those suffering from hypertension and other vascular diseases. “The idea was to add independent mechanical properties to 3D structures that can mimic the body’s natural tissue,” said Xiaobo Yin, an associate professor in CU Boulder’s Department of Mechanical Engineering and senior author of the study. “This technology allows us to create microstructures that can be […]
