Question: What is the hardest part of the body to replicate using a 3D printer?

Honestly I wouldn’t know, I have currently only really been working on trying repair bone and cartilage. There are other people investigating using 3D printing for skin regeneration also. In my opinion though the brain is the most complex organ in the body I don’t thing we will ever be able to 3D print the brain.
