[blindkid] Tactile Graphics

[Richard Holloway]

Yes, and I think the term used for the application was "rapid prototyping". No matter which actual process is used, if it produces stable models and becomes affordable enough, I'd love to have one, or gain access to one for some pieces my daughter could explore and use from time to time.
