Collaborators from Virginia Tech and some universities have developed a 3D Prined Guide that can actually help regrow the nerves. Although nerve damage is permanent, and it is impossible for them to regenerate, while 3D Printing comes just at time to make things possible.

Liqun Ning, a post-doctoral fellow in the Tissue Engineering Research Group at the University of Saskatchewan, is working on 3D Printing Scaffolds of Schwann Cells, the supporting cells in the nervous system that can force nerve cells to grow properly, which were created using the Canadian Light Source center at the University of Saskatchewan. The scaffolds are expected to stimulate new, healthy nerve cells to grow. The results of the study show that the 3D printed scaffolds can promote the alignment of the Schwann cells and provide cues to direct the extension of dorsal root ganglion along the printed strands.
