This method is used for making cast parts with internal passages and flanges that can not be machined otherwise.
Yes I could use the traditional sand cores but then I would have to make molds for all the cores as well. With 3D printing I could print all of the "cores" in place in the first go round...

It would also be a good way to produce a mold for composite parts.
