With the right 3d printer, you can print out servo-driven anthropomorphic robot hands: http://www.youtube.com/watch?v=BAs2F4sFVdA Whether that's useful or just an interesting-but-expensive model making hobby is a matter of opinion!

I think the designer may have a higher-end 3D printer than we're discussing here - he mentions a 3D touch, and they start at $3500ish.
