There's a lot of 3D printing of human figures going on, Alan, and it's getting better all the time. In my own industry, more and more manufacturers are changing to 3D design and print to produce master figures - I've been investigating it myself, though at present I'm sticking with my traditional hands-on sculptors; but I do have a sample here from a 3D print master that I have run some casting trials on, a WW2 German infantryman printed out about 28mm tall, with every crease and fold of the uniform perfectly reproduced.
It would be relatively straightforward for a good, experienced 3D artist to render figures like these, and then have them printed in any scale desired from Z to 7/8ths - all of which would be absolutely identical except for the size!
