Re: 2D pic -> 3D model
You need a program that exports as .stl
Besides that for posing you would need to weight the mesh to a skeleton that you would then pose. In 3ds Max you'd use Biped.
Besides that, you need to make sure that there aren't any holes in the mesh, and that everything is the proper size which includes making sure that there's correct thickness on each part. Besides that, you would need to make it smoother because any face would end up as a facet (like a diamond) once it's printed. If the polygons aren't small enough then they'll show up in the 3D print.
