Scientists create a way to make more breathable 3D-printed tissues
3D printing may be more commonly associated with things like rapid prototyping for industry and homemade “maker” projects, but it also opens up some exciting medical possibilities. Chief among these is the dream of 3D bioprinting, which could one day prove useful for everything from printingsmall-scale fabricated tissuesto the eventual goal of fully functional transplant organs. While the second of these ambitions is still a way off, researchers at Pennsylvania State University have made a big advance in the goal of creating lab-made tissues such as bone and cartilage....
