Here is a link to an interview on CNN demonstrating a 3-D printer for home use. Cost $1,300.
This printer created a wearable shoe and full-color mini-bust of the host.
Discussion of the 1″ tall mini-bust:
Host: “And then you painted it?”
Guest: “No, this one was printed in full color.”
Cost factors are beyond what I’d be interested in, but quite reasonable if you are a garage inventor or tinkerer. Remember what’s happened with costs of color laser printers.
