Orthogonal programming of matrix stiffness and geometry via oxygen inhibition-assisted stereolithography.
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.
The findings could one day lead to better, more personalized treatments for those suffering from hypertension and other vascular diseases...
