Lawrence Livermore National Laboratory – Researchers 3D Print ‘Living’ Blood Vessels

By Lawrence Livermore National Laboratory The cardiovascular system is a complex web of tens of thousands of miles of arteries, capillaries and veins, branching throughout the body like tributaries of a great river. And now, researchers at Lawrence Livermore National Laboratory are recapitulating this intricate Read More »
