Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models
Advanced Materials Technologies, EarlyView.Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.
