3D-Printing Strong High-Resolution Antioxidant Bioresorbable Vascular Stents

3D-printed stents are fabricated with high speed and resolution by micro-continuous liquid interface production (microCLIP) of a bioresorbable, antioxidant, photopolymerizable polydiolcitrate biomaterial. Printed stents can match the mechanical properties of bare metal stents and strengthen porcine arteries after deployment. This technology is a big step forward toward on-the-spot and on-demand printing of patient-specific stents.
