Abstrakt:	306Three-dimensional (3D)-printed vascular models for cardiovascular surgery planning and endovascular procedure simulations often lack realistic biological tissues mimicking material properties, including flexibility or transparency, or both. Transparent silicone or silicone-like vascular models were not available for end-user 3D printers and had to be fabricated using complex and cost-intensive workarounds. This limitation has now been overcome by novel liquid resins with biological tissue properties. These new materials enable simple and low-cost fabrication of transparent and flexible vascular models using end-user stereolithography 3D printers and are promising technological advances toward more realistic patient-specific, radiation-free procedure simulations and planning in cardiovascular surgery and interventional radiology. This paper presents our patient-specific manufacturing process of fabricating transparent and flexible vascular models using freely available open-source software for segmentation and 3D post-processing, aiming to facilitate the integration of 3D printing into clinical care.
