If it's just raised ridges, I was doing that 15 years ago with photo etch plates. The metal plates last a lot longer than the polymer from a printer, can do impressions into paper or leather with a press, can be used for rubbings as you wish to do, can be used for pseudo-litho prints with ink or paint... using 3D equipment for an essentially 2D output seems to be making things more complex and technical than they need to be, but then I probably have a different range of experiences, and correspondingly different comfort zones...
