Just because you can, doesn't mean you should (3D Printing) via @sparkfun | | #3Dprint…

It would be interesting if there was a way to 3-D Print sand castings. Then you could make your own castings of something and then actually pour metal into the casting. I am thinking something like making a actual working turbocharger or something like that. Yeah plastic is nice, but it does not always hold up to the heat for some projects. (Yeah, you would have to do some tooling on your project, but this would bring you one step closer to having a working project.) I am almost thinking something like what you make for ballast for model railroad track- a mixture of sand, dish soap, glue, and water. Problem would be how to get it to dry quickly, and be put through a small nozzle. Yeah you would have to have one of those box sand blasters to clear the sand castings, but that would still be a lot quicker.
