Researchers at the Hebrew University of Jerusalem’s Center for Nanoscience and Nanotechnology are using novel hybrid nanoparticles and water – which could benefit old and new industries including printing artificial organs. The new process involves using semiconductor-metal hybrid nanoparticles (HNPs) known as photoinitiators for 3D printing in water. 3D printing in water also offers an environmentally friendly approach to additive manufacturing, which could replace the current technology of printing in organic based inks. Printing in water opens exciting opportunities in the biomedical arena for tailored fabrication of medical devices and for printing scaffolds for tissue engineering, they said. For example, the researchers envision personalized fabrication of joint replacements, bone plates, heart valves, artificial tendons and ligaments and other artificial organ replacements.
