I did this 6in scale body a while ago in ABS, pretty posable. Been since working on acetone smoothing, sanding and painting to get a good finish, but honestly as
>>6245815said, 3D printing will only save you the major physical sculpting troubles. you have to know how to finish or recast them.
Even the figures I painted up after a lot of smoothing have sculpt and detail issues because of the way things print. Be prepared to sculpt things back in if you want a 'perfect' figure.
