Printed organs made from cells and genetically engineered might be better than what we have. The body is a brilliantly complicated thing and it will be incredibly hard for us to make artifical organs as replacements because an organ is essentially a machine built of many tiny machines and the body has a lot of functions to clean and repair itself that a plastic organ simply wouldn't: macrophages that move withing the tissue, different types of nervous and sensory tissue that innervate different organs, the lymphatic system, etc. No artifical organs can top that right now.
