I'd think that if the typical students dream is be a jeweler or metal artist that it's better to stick with a more basic vacuum and spring operated centrifugal casting set up. That's what most makers use, one or the other, or both. Only when they begin volume manufacturing would they look at the more expensive systems in their future working lives. They'd likely start out with vacuum and spinning.
Better to spend that money on cad software and an inexpensive growing machine. They will need to be exposed to and understand that if they are hoping to make a living in the field.
