Fabrication Speed Optimization for High-resolution 3D-printing of Bioresorbable Vascular Scaffolds

Year: 2017

Type: article

Abstract: The recent development of Continuous Liquid Interface Production, also known as CLIP, has successfully alleviated the main obstacles surrounding 3D printing technologies: production speed and part quality. Based on this technology, we developed the μCLIP process to allow for 3D printing of biomedical devices with micron-scale precision. In this study, we report the process development in manufacturing high-resolution bioresorbable scaffolds using our own μCLIP system and a bioresorbable photopolymerizable biomaterial (B-Ink). Through optimization of our μCLIP process and concentration of B-Ink components, we have reduced the fabrication time of a customizable BVSs from several hours to 11.25 minutes. Optimized ink was shown to possess mechanical stiffness comparable to a nitinol control stent.
