3D Modeling for the Blind

There are some doctors out there that are helping the blind by printing out 3D models so that they can touch and see with there hands. Examples of this would be a blind soon to be mother visiting her doctor for an ultrasound but since she is blind she can only take her doctors word and descriptions of what the baby looks like, however the doctor took the picture and sent it out to have it 3D printed so when she came back for another ultrasound she then could see her child by touching it.
