Bioinspired Heart Valve Prosthesis and Cellular Scaffolds by Silicone 3D Printing – Presented by Fergal Coulter, ETH Zurich – Complex Materials, at the 3D Medical Conference, which takes place on January 30-31, 2019, at MECC Maastricht, The Netherlands.
Artificial heart valves are highly demanded medical devices, but suffer from inferior performance compared to their biological counterparts. To tackle the poor longevity and hemodynamic behavior of many synthetic valves, an additive manufacturing platform was developed that enables the fabrication of polymer heart valves that are customizable to the patient and feature unique biologically-inspired leaflet designs.
Exploiting the shaping freedom of additive manufacturing, the synthetic valves are customized using geometries tailored to fit the anatomy of the patient. The architecture of the leaflet is designed to mimic the fiber reinforcement found in a natural valve.

Researchers at the federal technology institute ETH Zurich have developed a way of producing body parts containing cartilage, with the help of a 3D printer. Continue reading “Swiss researchers have harnessed 3D printing to produce cellular material”
Bioprinting is an emerging technology for the fabrication of patient-specific, anatomically-complex cartilage organs. Bioinks based on regulatory-compliant polysaccharides are being developed which undergoes cell friendly gelation and yield a strong, ductile material. To make bioinks more tissue-specific and bioactive, micronized extracellular matrix particles can be added. As examples, 3D auricular, nasal, meniscal and vertebral disc grafts based on computer tomography (CT) data or generic 3D models are shown. The bioink supports proliferation and deposition of matrix proteins. This versatile bioprinting method can produce patient-specific cartilage grafts with good mechanical and biological properties.
