Well for one thing the spinal cord lies within the lamina of the vertebrae thus preventing an easy replacement of a damaged vertebrae. This alone makes it rather impractical to replace them. As someone who has had the lamina of L-3 - L-5 removed due to having numerous disk herniated I know a little about it. Now if you had suggested 3d printed disks I would think it very possible.
